   DI 34125.009 Digestive Listings from 12/18/07 to 1/16/17
   
   
   
   5.00 DIGESTIVE SYSTEM (Effective Date: 12/18/07)
   
   A. What kinds of disorders do we consider in the digestive system? 
   
   Disorders of the digestive system include gastrointestinal hemorrhage, hepatic (liver)
      dysfunction, inflammatory bowel disease, short bowel syndrome, and malnutrition. They
      may also lead to complications, such as obstruction, or be accompanied by manifestations
      in other body systems.
   
   
   B. What documentation do we need? 
   
   We need a record of your medical evidence, including clinical and laboratory findings.
      The documentation should include appropriate medically acceptable imaging studies
      and reports of endoscopy, operations, and pathology, as appropriate to each listing,
      to document the severity and duration of your digestive disorder. Medically acceptable
      imaging includes, but is not limited to, x-ray imaging, sonography, computerized axial
      tomography (CAT scan), magnetic resonance imaging (MRI), and radionuclide scans. Appropriate means that the technique used is the proper one to support the evaluation and diagnosis
      of the disorder. The findings required by these listings must occur within the period
      we are considering in connection with your application or continuing disability review.
   
   
   C. How do we consider the effects of treatment? 
   
   1. Digestive disorders frequently respond to medical or surgical treatment; therefore,
      we generally consider the severity and duration of these disorders within the context
      of prescribed treatment.
   
   
   2. We assess the effects of treatment, including medication, therapy, surgery, or
      any other form of treatment you receive, by determining if there are improvements
      in the symptoms, signs, and laboratory findings of your digestive disorder. We also
      assess any side effects of your treatment that may further limit your functioning.
   
   
   3. To assess the effects of your treatment, we may need information about:
   
   a. The treatment you have been prescribed (for example, the type of medication or
      therapy, or your use of parenteral (intravenous) nutrition or supplemental enteral
      nutrition via a gastrostomy);
   
   
   b. The dosage, method, and frequency of administration;
   
   c. Your response to the treatment;
   
   d. Any adverse effects of such treatment; and
   
   e. The expected duration of the treatment.
   
   4. Because the effects of treatment may be temporary or long-term, in most cases we
      need information about the impact of your treatment, including its expected duration
      and side effects, over a sufficient period of time to help us assess its outcome.
      When adverse effects of treatment contribute to the severity of your impairment(s),
      we will consider the duration or expected duration of the treatment when we assess
      the duration of your impairment(s).
   
   
   5. If you need parenteral (intravenous) nutrition or supplemental enteral nutrition
      via a gastrostomy to avoid debilitating complications of a digestive disorder, this
      treatment will not, in itself, indicate that you are unable to do any gainful activity,
      except under 5.07, short bowel syndrome (see 5.00F).
   
   
   6. If you have not received ongoing treatment or have not had an ongoing relationship
      with the medical community despite the existence of a severe impairment(s), we will
      evaluate the severity and duration of your digestive impairment on the basis of the
      current medical and other evidence in your case record. If you have not received treatment,
      you may not be able to show an impairment that meets the criteria of one of the digestive
      system listings, but your digestive impairment may medically equal a listing or be
      disabling based on consideration of your residual functional capacity, age, education,
      and work experience.
   
   
   D. How do we evaluate chronic liver disease? 
   
   1. General. Chronic liver disease is characterized by liver cell necrosis, inflammation, or scarring (fibrosis or cirrhosis),
      due to any cause, that persists for more than 6 months. Chronic liver disease may
      result in portal hypertension, cholestasis (suppression of bile flow), extrahepatic
      manifestations, or liver cancer. (We evaluate liver cancer under 13.19.) Significant
      loss of liver function may be manifested by hemorrhage from varices or portal hypertensive
      gastropathy, ascites (accumulation of fluid in the abdominal cavity), hydrothorax
      (ascitic fluid in the chest cavity), or encephalopathy. There can also be progressive
      deterioration of laboratory findings that are indicative of liver dysfunction. Liver
      transplantation is the only definitive cure for end stage liver disease (ESLD).
   
   
   2. Examples of chronic liver disease include, but are not limited to, chronic hepatitis, alcoholic liver disease, non-alcoholic
      steatohepatitis (NASH), primary biliary cirrhosis (PBC), primary sclerosing cholangitis
      (PSC), autoimmune hepatitis, hemochromatosis, drug-induced liver disease, Wilson’s
      disease, and serum alpha-1 antitrypsin deficiency. Acute hepatic injury is frequently
      reversible, as in viral, drug-induced, toxin-induced, alcoholic, and ischemic hepatitis.
      In the absence of evidence of a chronic impairment, episodes of acute liver disease
      do not meet 5.05.
   
   
   3. Manifestations of chronic liver disease.
   
   a. Symptoms may include, but are not limited to, pruritis (itching), fatigue, nausea, loss of
      appetite, or sleep disturbances. Symptoms of chronic liver disease may have a poor
      correlation with the severity of liver disease and functional ability.
   
   
   b. Signs may include, but are not limited to, jaundice, enlargement of the liver and spleen,
      ascites, peripheral edema, and altered mental status.
   
   
   c. Laboratory findings may include, but are not limited to, increased liver enzymes, increased serum total
      bilirubin, increased ammonia levels, decreased serum albumin, and abnormal coagulation
      studies, such as increased International Normalized Ratio (INR) or decreased platelet
      counts. Abnormally low serum albumin or elevated INR levels indicate loss of synthetic
      liver function, with increased likelihood of cirrhosis and associated complications.
      However, other abnormal lab tests, such as liver enzymes, serum total bilirubin, or
      ammonia levels, may have a poor correlation with the severity of liver disease and
      functional ability. A liver biopsy may demonstrate the degree of liver cell necrosis,
      inflammation, fibrosis, and cirrhosis. If you have had a liver biopsy, we will make
      every reasonable effort to obtain the results; however, we will not purchase a liver
      biopsy. Imaging studies (CAT scan, ultrasound, MRI) may show the size and consistency
      (fatty liver, scarring) of the liver and document ascites (see 5.00D6).
   
   
   4. Chronic viral hepatitis infections.
   
   a. General.
   
   (i) Chronic viral hepatitis infections are commonly caused by hepatitis C virus (HCV), and to a lesser extent,
      hepatitis B virus (HBV). Usually, these are slowly progressive disorders that persist
      over many years during which the symptoms and signs are typically nonspecific, intermittent,
      and mild (for example, fatigue, difficulty with concentration, or right upper quadrant
      pain). Laboratory findings (liver enzymes, imaging studies, liver biopsy pathology)
      and complications are generally similar in HCV and HBV. The spectrum of these chronic
      viral hepatitis infections ranges widely and includes an asymptomatic state; insidious
      disease with mild to moderate symptoms associated with fluctuating liver tests; extrahepatic
      manifestations; cirrhosis, both compensated and decompensated; ESLD with the need
      for liver transplantation; and liver cancer. Treatment for chronic viral hepatitis
      infections varies considerably based on medication tolerance, treatment response,
      adverse effects of treatment, and duration of the treatment. Comorbid disorders, such
      as HIV infection, may affect the clinical course of viral hepatitis infection(s) or
      may alter the response to medical treatment.
   
   
   (ii) We evaluate all types of chronic viral hepatitis infections under 5.05 or any
      listing in an affected body system(s). If your impairment(s) does not meet or medically
      equal a listing, we will consider the effects of your hepatitis when we assess your
      residual functional capacity.
   
   
   b. Chronic hepatitis B virus (HBV) infection.
   
   (i) Chronic HBV infection is diagnosed by the detection of hepatitis B surface antigen (HBsAg) in
      the blood for at least 6 months. In addition, detection of the hepatitis B envelope
      antigen (HBeAg) suggests an increased likelihood of progression to cirrhosis and ESLD.
   
   
   (ii) The therapeutic goal of treatment is to suppress HBV replication and thereby
      prevent progression to cirrhosis and ESLD. Treatment usually includes a combination
      of interferon injections and oral antiviral agents. Common adverse effects of treatment
      are the same as noted in 5.00D4c(ii) for HCV, and generally end within a few days
      after treatment is discontinued.
   
   
   c. Chronic hepatitis C virus (HCV) infection.
   
   (i) Chronic HCV infection is diagnosed by the detection of hepatitis C viral RNA in the blood for at least
      6 months. Documentation of the therapeutic response to treatment is also monitored
      by the quantitative assay of serum HCV RNA (“HCV viral load”). Treatment usually includes
      a combination of interferon injections and oral ribavirin; whether a therapeutic response
      has occurred is usually assessed after 12 weeks of treatment by checking the HCV viral
      load. If there has been a substantial reduction in HCV viral load (also known as early
      viral response, or EVR), this reduction is predictive of a sustained viral response
      with completion of treatment. Combined therapy is commonly discontinued after 12 weeks
      when there is no early viral response, since in that circumstance there is little
      chance of obtaining a sustained viral response (SVR). Otherwise, treatment is usually
      continued for a total of 48 weeks.
   
   
   (ii) Combined interferon and ribavirin treatment may have significant adverse effects
      that may require dosing reduction, planned interruption of treatment, or discontinuation
      of treatment. Adverse effects may include: Anemia (ribavirin-induced hemolysis), neutropenia,
      thrombocytopenia, fever, cough, fatigue, myalgia, arthralgia, nausea, loss of appetite,
      pruritis, and insomnia. Behavioral side effects may also occur. Influenza-like symptoms
      are generally worse in the first 4 to 6 hours after each interferon injection and
      during the first weeks of treatment. Adverse effects generally end within a few days
      after treatment is discontinued.
   
   
   d. Extrahepatic manifestations of HBV and HCV. In addition to their hepatic manifestations, both HBV and HCV may have significant
      extrahepatic manifestations in a variety of body systems. These include, but are not
      limited to: Keratoconjunctivitis (sicca syndrome), glomerulonephritis, skin disorders
      (for example, lichen planus, porphyria cutanea tarda), neuropathy, and immune dysfunction
      (for example, cryoglobulinemia, Sjögren’s syndrome, and vasculitis). The extrahepatic
      manifestations of HBV and HCV may not correlate with the severity of your hepatic
      impairment. If your impairment(s) does not meet or medically equal a listing in an
      affected body system(s), we will consider the effects of your extrahepatic manifestations
      when we assess your residual functional capacity.
   
   
   5. Gastrointestinal hemorrhage (5.02 and 5.05A). Gastrointestinal hemorrhaging can result in hematemesis (vomiting
      of blood), melena (tarry stools), or hematochezia (bloody stools). Under 5.02, the
      required transfusions of at least 2 units of blood must be at least 30 days apart
      and occur at least three times during a consecutive 6-month period. Under 5.05A, hemodynamic instability is diagnosed with signs such as pallor (pale skin), diaphoresis (profuse perspiration),
      rapid pulse, low blood pressure, postural hypotension (pronounced fall in blood pressure
      when arising to an upright position from lying down) or syncope (fainting). Hemorrhaging
      that results in hemodynamic instability is potentially life-threatening and therefore
      requires hospitalization for transfusion and supportive care. Under 5.05A, we require
      only one hospitalization for transfusion of at least 2 units of blood.
   
   
   6. Ascites or hydrothorax (5.05B) indicates significant loss of liver function due to chronic liver disease.
      We evaluate ascites or hydrothorax that is not attributable to other causes under
      5.05B. The required findings must be present on at least two evaluations at least
      60 days apart within a consecutive 6-month period and despite continuing treatment
      as prescribed.
   
   
   7. Spontaneous bacterial peritonitis (5.05C) is an infectious complication of chronic liver disease. It is diagnosed by
      ascitic peritoneal fluid that is documented to contain an absolute neutrophil count
      of at least 250 cells/mm3. The required finding in 5.05C is satisfied with one evaluation documenting peritoneal
      fluid infection. We do not evaluate other causes of peritonitis that are unrelated
      to chronic liver disease, such as tuberculosis, malignancy, and perforated bowel,
      under this listing. We evaluate these other causes of peritonitis under the appropriate
      body system listings.
   
   
   8. Hepatorenal syndrome (5.05D) is defined as functional renal failure associated with chronic liver disease
      in the absence of underlying kidney pathology. Hepatorenal syndrome is documented
      by elevation of serum creatinine, marked sodium retention, and oliguria (reduced urine
      output). The requirements of 5.05D are satisfied with documentation of any one of
      the three laboratory findings on one evaluation. We do not evaluate known causes of
      renal dysfunction, such as glomerulonephritis, tubular necrosis, drug-induced renal
      disease, and renal infections, under this listing. We evaluate these other renal impairments
      under 6.00.
   
   
   9. Hepatopulmonary syndrome (5.05E) is defined as arterial deoxygenation (hypoxemia) that is associated with
      chronic liver disease due to intrapulmonary arteriovenous shunting and vasodilatation
      in the absence of other causes of arterial deoxygenation. Clinical manifestations
      usually include dyspnea, orthodeoxia (increasing hypoxemia with erect position), platypnea
      (improvement of dyspnea with flat position), cyanosis, and clubbing. The requirements
      of 5.05E are satisfied with documentation of any one of the findings on one evaluation.
      In 5.05E1, we require documentation of the altitude of the testing facility because
      altitude affects the measurement of arterial oxygenation. We will not purchase the
      specialized studies described in 5.05E2; however, if you have had these studies at
      a time relevant to your claim, we will make every reasonable effort to obtain the
      reports for the purpose of establishing whether your impairment meets 5.05E2.
   
   
   10. Hepatic encephalopathy (5.05F).
   
   
   a. General. Hepatic encephalopathy usually indicates severe loss of hepatocellular function.
      We define hepatic encephalopathy under 5.05F as a recurrent or chronic neuropsychiatric
      disorder, characterized by abnormal behavior, cognitive dysfunction, altered state
      of consciousness, and ultimately coma and death. The diagnosis is established by changes
      in mental status associated with fleeting neurological signs, including “flapping
      tremor” (asterixis), characteristic electroencephalographic (EEG) abnormalities, or
      abnormal laboratory values that indicate loss of synthetic liver function. We will
      not purchase the EEG testing described in 5.05F3b; however, if you have had this test
      at a time relevant to your claim, we will make every reasonable effort to obtain the
      report for the purpose of establishing whether your impairment meets 5.05F.
   
   
   b. Acute encephalopathy. We will not evaluate your acute encephalopathy under 5.05F if it results from conditions
      other than chronic liver disease, such as vascular events and neoplastic diseases.
      We will evaluate these other causes of acute encephalopathy under the appropriate
      body system listings.
   
   
   11. End stage liver disease (ESLD) documented by scores from the SSA Chronic Liver Disease
         (SSA CLD) calculation (5.05G).
   
   
   a. We will use the SSA CLD score to evaluate your ESLD under 5.05G. We explain how
      we calculate the SSA CLD score in b. through g. of this section.
   
   
   b. To calculate the SSA CLD score, we use a formula that includes three laboratory
      values: Serum total bilirubin (mg/dL), serum creatinine (mg/dL), and International
      Normalized Ratio (INR). The formula for the SSA CLD score calculation is:
   
   
   9.57 x [Loge(serum creatinine mg/dL)]
   
   
   +3.78 x [Loge(serum total bilirubin mg/dL)]
   
   
   +11.2 x [Loge(INR)]
   
   
   +6.43
   
   c. When we indicate “Loge” in the formula for the SSA CLD score calculation, we mean the “base e logarithm” or “natural logarithm” (ln) of a numerical laboratory value, not the “base
      10 logarithm” or “common logarithm” (log) of the laboratory value, and not the actual
      laboratory value. For example, if an individual has laboratory values of serum creatinine
      1.2 mg/dL, serum total bilirubin 2.2 mg/dL, and INR 1.0, we would compute the SSA
      CLD score as follows:
   
   
   9.57 x [Loge(serum creatinine 1.2 mg/dL) = 0.182]
   
   
   +3.78 x [Loge(serum total bilirubin 2.2 mg/dL) = 0.788]
   
   
   +11.2 x [Loge(INR 1.0) = 0]
   
   
   +6.43
   
   _____
   
   = 1.74 + 2.98 + 0 + 6.43
   
   = 11.15, which is then rounded to an SSA CLD score of 11.
   
   d. For any SSA CLD score calculation, all of the required laboratory values must have
      been obtained within 30 days of each other. If there are multiple laboratory values
      within the 30-day interval for any given laboratory test (serum total bilirubin, serum
      creatinine, or INR), we will use the highest value for the SSA CLD score calculation.
      We will round all laboratory values less than 1.0 up to 1.0.
   
   
   e. Listing 5.05G requires two SSA CLD scores. The laboratory values for the second
      SSA CLD score calculation must have been obtained at least 60 days after the latest
      laboratory value for the first SSA CLD score and within the required 6-month period.
      We will consider the date of each SSA CLD score to be the date of the first laboratory
      value used for its calculation.
   
   
   f. If you are in renal failure or on dialysis within a week of any serum creatinine
      test in the period used for the SSA CLD calculation, we will use a serum creatinine
      of 4, which is the maximum serum creatinine level allowed in the calculation, to calculate
      your SSA CLD score.
   
   
   g. If you have the two SSA CLD scores required by 5.05G, we will find that your impairment
      meets the criteria of the listing from at least the date of the first SSA CLD score.
   
   
   12. Liver transplantation (5.09) may be performed for metabolic liver disease, progressive liver failure, life-threatening
      complications of liver disease, hepatic malignancy, and acute fulminant hepatitis
      (viral, drug-induced, or toxin-induced). We will consider you to be disabled for 1
      year from the date of the transplantation. Thereafter, we will evaluate your residual
      impairment(s) by considering the adequacy of post-transplant liver function, the requirement
      for post-transplant antiviral therapy, the frequency and severity of rejection episodes,
      comorbid complications, and all adverse treatment effects.
   
   
   E. How do we evaluate inflammatory bowel disease (IBD)? 
   
   1. Inflammatory bowel disease (5.06) includes, but is not limited to, Crohn's disease and ulcerative colitis. These
      disorders, while distinct entities, share many clinical, laboratory, and imaging findings,
      as well as similar treatment regimens. Remissions and exacerbations of variable duration
      are the hallmark of IBD. Crohn’s disease may involve the entire alimentary tract from
      the mouth to the anus in a segmental, asymmetric fashion. Obstruction, stenosis, fistulization,
      perineal involvement, and extraintestinal manifestations are common. Crohn's disease
      is rarely curable and recurrence may be a lifelong problem, even after surgical resection.
      In contrast, ulcerative colitis only affects the colon. The inflammatory process may
      be limited to the rectum, extend proximally to include any contiguous segment, or
      involve the entire colon. Ulcerative colitis may be cured by total colectomy.
   
   
   2. Symptoms and signs of IBD include diarrhea, fecal incontinence, rectal bleeding,
      abdominal pain, fatigue, fever, nausea, vomiting, arthralgia, abdominal tenderness,
      palpable abdominal mass (usually inflamed loops of bowel) and perineal disease. You
      may also have signs or laboratory findings indicating malnutrition, such as weight
      loss, edema, anemia, hypoalbuminemia, hypokalemia, hypocalcemia, or hypomagnesemia.
   
   
   3. IBD may be associated with significant extraintestinal manifestations in a variety
      of body systems. These include, but are not limited to, involvement of the eye (for
      example, uveitis, episcleritis, iritis); hepatobiliary disease (for example, gallstones,
      primary sclerosing cholangitis); urologic disease (for example, kidney stones, obstructive
      hydronephrosis); skin involvement (for example, erythema nodosum, pyoderma gangrenosum);
      or non-destructive inflammatory arthritis. You may also have associated thromboembolic
      disorders or vascular disease. These manifestations may not correlate with the severity
      of your IBD. If your impairment does not meet any of the criteria of 5.06, we will
      consider the effects of your extraintestinal manifestations in determining whether
      you have an impairment(s) that meets or medically equals another listing, and we will
      also consider the effects of your extraintestinal manifestations when we assess your
      residual functional capacity.
   
   
   4. Surgical diversion of the intestinal tract, including ileostomy and colostomy,
      does not preclude any gainful activity if you are able to maintain adequate nutrition
      and function of the stoma. However, if you are not able to maintain adequate nutrition,
      we will evaluate your impairment under 5.08.
   
   
   F. How do we evaluate short bowel syndrome (SBS)? 
   
   1. Short bowel syndrome (5.07) is a disorder that occurs when ischemic vascular insults (for example, volvulus),
      trauma, or IBD complications require surgical resection of more than one-half of the
      small intestine, resulting in the loss of intestinal absorptive surface and a state
      of chronic malnutrition. The management of SBS requires long-term parenteral nutrition
      via an indwelling central venous catheter (central line); the process is often referred
      to as hyperalimentation or total parenteral nutrition (TPN). Individuals with SBS can also feed orally, with variable amounts of nutrients
      being absorbed through their remaining intestine. Over time, some of these individuals
      can develop additional intestinal absorptive surface, and may ultimately be able to
      be weaned off their parenteral nutrition.
   
   
   2. Your impairment will continue to meet 5.07 as long as you remain dependent on daily
      parenteral nutrition via a central venous catheter for most of your nutritional requirements.
      Long-term complications of SBS and parenteral nutrition include central line infections
      (with or without septicemia), thrombosis, hepatotoxicity, gallstones, and loss of
      venous access sites. Intestinal transplantation is the only definitive treatment for
      individuals with SBS who remain chronically dependent on parenteral nutrition.
   
   
   3. To document SBS, we need a copy of the operative report of intestinal resection,
      the summary of the hospitalization(s) including: Details of the surgical findings,
      medically appropriate postoperative imaging studies that reflect the amount of your
      residual small intestine, or if we cannot get one of these reports, other medical
      reports that include details of the surgical findings. We also need medical documentation
      that you are dependent on daily parenteral nutrition to provide most of your nutritional
      requirements.
   
   
   G. How do we evaluate weight loss due to any digestive disorder? 
   
   1. In addition to the impairments specifically mentioned in these listings, other
      digestive disorders, such as esophageal stricture, pancreatic insufficiency, and malabsorption,
      may result in significant weight loss. We evaluate weight loss due to any digestive
      disorder under 5.08 by using the Body Mass Index (BMI). We also provide a criterion
      in 5.06B for lesser weight loss resulting from IBD.
   
   
   2. BMI is the ratio of your weight to the square of your height. Calculation and interpretation
      of the BMI are independent of gender in adults.
   
   
   a. We calculate BMI using inches and pounds, meters and kilograms, or centimeters
      and kilograms. We must have measurements of your weight and height without shoes for
      these calculations.
   
   
   b. We calculate BMI using one of the following formulas:
   
   English Formula
   
   
      
         
         
            
            
               
               | BMI = ( |             Weight in Pounds             (Height in Inches) x (Height in Inches)
 | ) x 703 |   | 
         
      
    
   Metric Formula
   
   
      
         
         
            
            
               
               | BMI = |             Weight in Kilograms             (Height in Meters) x (Height in Meters)
 |   |   | 
            
               
               |   | Or |   |   | 
            
               
               | BMI = ( |             Weight in Kilograms             (Height in Centimeters) x (Height in Centimeters)
 | ) x 10,000 |   | 
         
      
    
   H. What do we mean by the phrase “consider under a disability for 1 year”? 
   
   We use the phrase “consider under a disability for 1 year” following a specific event
      in 5.02, 5.05A, and 5.09 to explain how long your impairment can meet the requirements
      of those particular listings. This phrase does not refer to the date on which your
      disability began, only to the date on which we must reevaluate whether your impairment
      continues to meet a listing or is otherwise disabling. For example, if you have received
      a liver transplant, you may have become disabled before the transplant because of
      chronic liver disease. Therefore, we do not restrict our determination of the onset
      of disability to the date of the specified event. We will establish an onset date
      earlier than the date of the specified event if the evidence in your case record supports
      such a finding.
   
   
   I. How do we evaluate impairments that do not meet one of the digestive disorder listings?
         
   
   1. These listings are only examples of common digestive disorders that we consider
      severe enough to prevent you from doing any gainful activity. If your impairment(s)
      does not meet the criteria of any of these listings, we must also consider whether
      you have an impairment(s) that satisfies the criteria of a listing in another body
      system. For example, if you have hepatitis B or C and you are depressed, we will evaluate
      your impairment under 12.04.
   
   
   2. If you have a severe medically determinable impairment(s) that does not meet a
      listing, we will determine whether your impairment(s) medically equals a listing.
      (See §§404.1526 and 416.926.) If your impairment(s) does not meet or medically equal
      a listing, you may or may not have the residual functional capacity to engage in substantial
      gainful activity. In this situation, we will proceed to the fourth, and if necessary,
      the fifth steps of the sequential evaluation process in §§404.1520 and 416.920. When
      we decide whether you continue to be disabled, we use the rules in §§404.1594, 416.994,
      and 416.994a as appropriate.
