HI 01001.011 Examples of Premium Increases for Late Enrollment


John Brown, age 65 and first eligible for Part B in 1/87, first enrolled on 2/15/89 (in the GEP beginning 1/1/89). The months considered in determining Mr. Brown's premium increase begin with 5/87 (the first month after the close of his IEP) and extend through 3/89 (see HI 01001.010 B.1.) for a total of 23 months. Since there is only one full 12-month period in 23 months, Mr. Brown's premium (beginning 7/89, the first month of SMI coverage) was 10 percent greater than if he had enrolled in his IEP.


Hetty Blue was born in 1899 and was therefore eligible to enroll in SMI during the initial general enrollment period (IGEP) ending 5/31/66. She first enrolled during the 1969 GEP,with coverage effective 7/69; her SMI was subsequently terminated effective 1/31/70 for nonpayment of premiums. Mrs. Blue next enrolled during the 1990 GEP with coverage effective 7/90. The following months are counted against her for purposes of the premium increase: 34 months for 6/66 - 3/69 inclusive, plus 242 for 2/70 -3/90 inclusive. The total number of countable months is 276 and Mrs. Blue must therefore pay a 230 percent increase in her premiums.


Irving Howard, who was born in 1899,and was eligible to enroll during the IGEP ending 5/31/66, first enrolled in 3/68 during the extended GEP. SSA terminated his coverage for nonpayment of premiums effective 9/30/68, and he reenrolled in 2/71. Under HI 01001.010 B.1. and B.2.b., Mr. Howard had 49 months chargeable against him (19 months for the period 6/66 -12/67, inclusive, plus 30 months for 10/68 - 3/71, inclusive) and had to pay a 40 percent increase in his premiums.


Oscar Hicks, who was born in 1900,and first eligible to enroll during the IGEP ending 5/31/66, first enrolled in the 1969 GEP (the last GEP in which he could have initially enrolled under the law then in effect). Shortly after coverage became effective (7/69), he terminated his SMI effective 12/31/ 69. Although eligible to reenroll in the next three GEP's, Mr. Hicks did not enroll until the 1973 GEP. The 1972 GEP was the last period in which he could enroll under the law in effect prior to the 1972 Amendments. Therefore, pursuant to HI 01001.010 B.2.e, no months between 4/72 and 12/72, inclusive,were counted against Mr. Hicks for purposes of the premium increase. Mr. Hicks had 64 months chargeable against him (34 months for 6/66 - 3/69, inclusive, plus 27 months for 1/70 - 3/72, inclusive, plus 3 months for 1 /73 - 3/73, inclusive) and he paid a 50 percent increase in the premiums.


1. Initial Enrollment and Reenrollment

Lou Brook enrolled in SMI effective with 5/1/75, the month he attained age 65. His enrollment terminated 12/31/75. He reenrolled during the 1977 GEP. His premium increased by 10 percent because 15 months had elapsed from the end of his first coverage period through 3/77 (the end of the 1977 GEP). This period of coverage terminated effective with 12/31/77.

2. Two - Enrollment Limit, 1981 Open Enrollment

He was then barred from reenrollment under the law in effect prior to 4/1/ 81.

With the repeal of the 2-enrollment limitation as of 4/1/81 and the institution of the open enrollment period (which concept only lasted from 4/1 /81 through 9/30/81, when it was repealed), Mr. Brook reenrolled in 7/ 81.

The only months charged against him for premium increase purposes were the 15 months between his first period of coverage and the end of the 1977 GEP plus the 4 months from 4/81 (the first month in which the law permitted a third enrollment) through 7/81, a total of 19 months. His premium was, therefore, still only increased by 10 percent.

3. If Enrollment Had Occurred In 1982

Had he not enrolled during the 4/81 through 9/81 open enrollment period but waited until the 1982 GEP to reenroll, his premium would have been increased by 20 percent because the 12 months 4/81 through 3/82 would be added to the 15 months that elapsed between his first 2 periods of coverage, a total of 27 months.

4. If Premium-HI Were Involved

If Mr. Brook had been uninsured and decided to enroll in Premium-HI also during 7/81,the months elapsing after the end of his original IEP (8/31/ 75) through the month of termination of his second period of SMI coverage (12 /77) plus the months 4/81 through 7/81 would be counted (a total of 32 months). The months after the termination of his second SMI enrollment and before 4/81 would not count since he was barred from Premium-HI enrollment because he could not have SMI entitlement during those months.

F. Example - Employer Group Health Plan (EGHP) Coverage and Special Enrollment Period (SEP)

Kirk Ford was born 11/11/21. He worked and was covered under an EGHP each month beginning prior to attainment of age 65 and continuing until his retirement in 8/88. In 8/88, he filed for HI, monthly benefits, and for SMI under SEP rules, submitting evidence that he was covered under an EGHP from age 65 onward. The months during which he was covered under an EGHP based on current employment were excludable for surcharge purposes. Therefore, since all months beginning with age 65 were months of coverage under an EGHP, he had no months chargeable against him for premium surcharge purposes.

G. Example - EGHP Coverage, No SEP Possible

Jerry Pendleton enrolled for HI in 9/82, the month he attained age 65. He did not enroll in SMI. During the 1988 GEP, he requested SMI enrollment. He had been covered under an EGHP from age 65 through 4/87, when he retired. Although he did not meet the requirements for a special enrollment period because more than 7 months had elapsed since his last coverage under an EGHP, the 63 months which would have been considered in determining the surcharge for late enrollment (1/83 through 3/88) were reduced by the 52 months when he had EGHP coverage (1/83 through 4/87), and Mr. Pendleton did not have to pay a surcharge for late enrollment.
