CMS clarifies Medicare priority relative to FEHBP for federal annuitants receiving OWCP benefits

What happened

The October 2 transmittal takes effect and is implemented November 2. CMS responds to an OPM benefits-booklet position that treated Medicare as secondary to FEHBP for federal annuitants receiving OWCP benefits. The updated manual says Medicare is primary to FEHBP when the beneficiary maintains that coverage, receives federal workers' compensation, and is deemed unable to return to work after six months. The explanation turns on compensationer/annuitant status and absence of coverage by reason of current employment, rather than merely the receipt of an OWCP payment.

The same manual retains the general workers' compensation rule: Medicare may not pay to the extent payment has been made or can reasonably be expected under a workers' compensation law or plan. A Medicare payment for services payable under that system can constitute an overpayment, and the beneficiary must take necessary timely steps to obtain those benefits. The FEHBP comparison therefore does not erase the need to identify a liable workers' compensation payer for a particular item or service. Payer-order scripts should distinguish the employer-plan comparison from compensability and other MSP questions.

Why it matters

Registration and coordination-of-benefits logic can incorrectly equate OWCP benefit receipt with current employment or FEHBP primacy.

Implementation playbook

1. Review federal-annuitant payer-order scripts and refer unusual workers compensation claims for separate MSP analysis. Patient Access · Due 2026-11-02
2. Record the applicability assessment and validate the affected workflow with its operational owner. This is an internal review target, not an additional statutory deadline. Compliance · Due 2026-10-12
