Medicare program; Medicare secondary payer for disabled active individuals--HCFA. Proposed rule.

This proposal sets forth the rules that limit Medicare payment for services furnished to disabled "active individuals" who are covered under a large group health plan (LGHP), and prohibit discrimination by an LGHP against such individuals. These rules are necessary to implement section 1862(b)(1)(B) of the Social Security Act (the Act), and related provisions, which make Medicare benefits secondary to LGHP benefits.
