COMPASSIONATE ALLOWANCES INFORMATION
|
CONGENITAL ZIKA SYNDROME
|
ALTERNATE NAMES
|
Zika virus disease; ZVD; CZS
|
DESCRIPTION
|
Congenital Zika syndrome (CZS) is a pattern of birth defects caused by in utero infection of the fetal brain with
theZika virus.
|
DIAGNOSTIC TESTING, PHYSICAL FINDINGS, AND ICD-9-CM/ICD-10-CM
CODING
|
Diagnostic testing:
-
•
Positive Zika virus NAAT (Nucleic Acid Amplification Test) and IgM in the blood and
CSF of the infant within a few days after birth; and
-
•
Positive plaque reduction neutralization testing (PRNT) at birth.
Physical findings: The physical findings below are usually seen in Zika syndrome but may also be seen
in other congenital infections of the fetal brain.
-
•
Severe microcephaly (abnormally small head);
-
•
Decreased brain tissue with a specific pattern of brain damage, including subcortical
calcifications;
-
•
Damage to the back of the eye, including macular scarring and focal retinal pigmentary
mottling;
-
•
Congenital contractures, such as clubfoot or arthrogryposis; and
-
•
Hypertonia restricting body movement soon after birth.
Other findings for CZS may include:
-
-
•
Progressive, irreversible intellectual disability;
-
•
Brain atrophy and asymmetry;
-
•
Abnormally formed or absent brain structures;
-
•
Hydrocephalus (accumulation of cerebrospinal fluid within the brain);
-
•
Neuronal migration disorders;
-
•
Excessive and redundant scalp skin;
-
•
Hyperreflexia (overactive or overresponsive reflexes);
-
-
-
-
-
•
Dyspagia (difficulty swallowing);
-
•
Chorioretinal atrophy in the macula;
-
•
Optic nerve hypoplasia, cupping, and atrophy;
-
-
•
Iris colobomas (holes in the iris);
-
-
•
Microphthalmia (abnormally small eyes);
-
-
-
•
Intraocular calcifications.
ICD-9: 066.3
ICD-10: A92.5
|
PROGRESSION
|
A small percentage of children born with microcephaly have normal intelligence. Most
children have issues with walking, communicating, coordination, and speech issues;
and need constant attention and care.
|
TREATMENT
|
There is no current treatment available for CZS. Some of the intervention programs
like occupational therapy, speech assistance, and special needs help can provide some
help.
|
SUGGESTED PROGRAMMATIC ASSESSMENT*
|
Suggested MER for Evaluation:
-
•
Clinical history and examination that describes the diagnostic features of the impairment;
-
•
Positive CZS-specific immunological testing;
-
•
Neuroimaging (cranial ultrasound, computed tomography, or magnetic resonance imaging)
any time after birth showing microcephaly; and
-
•
Brainstem auditory evoked response (BAER) to document hearing impairment.
