Medicare Secondary Payer Manual (Pub. 100-05), Ch. 1 § 20.3
Disabled Beneficiaries Covered Under a Large Group Health
20.3 - Disabled Beneficiaries Covered Under a Large Group Health
Plan (LGHP)
(Rev. 11755, Issued:12-21-22, Effective: 01-23-23, Implementation: 01-23-23)
Medicare is secondary to LGHPs for individuals under age 65 entitled to Medicare Part A
on the basis of disability and whose LGHP coverage is based on the individual’s current
employment status or the current employment status of a family member, pursuant to 42
CFR § 411.204. Under the law, a LGHP may not "take into account" that such an
individual is eligible for, or receives, Medicare benefits based on disability. The
instructions in §10.1 and throughout this manual that are applicable to GHPs are also
applicable to LGHPs in processing claims where Medicare is secondary payer for disabled
individuals. Where those sections refer to a GHP with 20 or more employees, substitute the
term "large group health plan" as defined in Pub. 100-05, Chapter 1, §40, to apply them to
disabled individuals.
Medicare is secondary to benefits payable under a LGHP for individuals under age 65
entitled to Medicare on the basis of disability who are covered under a LGHP as a result of
the:
i.
Individual's current employment status with an employer that has 100
employees or more (see Pub. 100-05, Chapter 2, §30.3 ); or
ii.
Current employment status of a family member with such employer (42 CFR
411.200).
Special rules apply in the case of multiple employers and multi-employer plans. (See Pub.
100-05, Chapter 2, §30.3.) Medicare is secondary for these Medicare beneficiaries even
though the employer policy or plan contains a provision stating that its benefits are
secondary to Medicare benefits or otherwise excludes or limits its payments to Medicare
beneficiaries.
Medicare is secondary payer to LGHP coverage based on an individual’s or family
members current employment status.
