Medicare Secondary Payer Manual (Pub. 100-05), Ch. 2 § 80.3.1
Paying Benefits Secondary to Medicare
80.3.1- Paying Benefits Secondary to Medicare
(Rev. 11755, Issued:12-21-2022, Effective: 01-23-2023, Implementation: 01-23-23)
The nondifferentiation provision does not prohibit a plan from paying benefits
secondary to Medicare after the coordination period. However, a plan may not
otherwise differentiate, as described in §70.2 and §70.3, in the benefits it provides.
EXAMPLE 1:
Mr. Smith works for employer A and he and his wife are covered through employer A's
GHP (Plan A). Neither is eligible for Medicare nor has ESRD. Mrs. Smith works for
employer B and is also covered by employer B's plan (Plan B). Plan A is more
comprehensive than Plan B and covers certain items and services, such as prescription
drugs, which Plan B does not cover. If Mrs. Smith obtains a medical service, Plan B pays
primary and Plan A pays secondary. That is, Plan A covers Plan B copayment amounts
and items and services that Plan A covers but that Plan B does not.
Mr. Jones also works for employer A and he and his wife are covered by Plan A. Mrs.
Jones does not have other GHP coverage. Mrs. Jones develops ESRD and becomes
entitled to Medicare on that basis. Plan A pays primary to Medicare during the first 30
months of Medicare entitlement based on ESRD. When Medicare becomes the primary
payer, the plan converts Mrs. Jones' coverage to a Medicare supplemental policy. That
policy pays Medicare's deductible and coinsurance amounts but does not pay for items
and services not covered by Medicare which Plan A would have covered. That
conversion is impermissible because the plan is providing a lower level of coverage for
Mrs. Jones who has ESRD than it provides for Mrs. Smith who does not. In other words,
if Plan A pays secondary to primary payers other than Medicare, it must provide the same
level of secondary benefits when Medicare is primary in order to comply with the
nondifferentiation provision.
