Medicare Advantage Is Not Medicare

The card says Medicare. The patient says Medicare. The claim is not billed like Medicare, and treating it as though it were is one of the most reliable sources of avoidable denials.

What an Advantage plan actually is

A private insurer contracts with the government to administer benefits. The beneficiary gets Medicare coverage, but through a commercial plan operating under its own rules.

Practically, that means a network you may or may not be in, authorization requirements traditional Medicare does not impose, a different filing window, a different appeal path, and its own coverage policies.

The specific failures

• Authorization not obtained. The most expensive one. Advantage plans require it for services traditional Medicare pays without question.
• Out of network. Participation in Medicare does not mean participation in every Advantage plan.
• Wrong appeal path. Advantage appeals follow the plan's process, not the Medicare redetermination path, and using the wrong one wastes the window.
• Filing window. Frequently shorter than Medicare's twelve months, and set by contract.
• Billed to the wrong payer entirely. Claims sent to the Medicare contractor for an Advantage enrollee deny — and the time spent discovering that came out of the plan's filing window.

The front-desk fix

Eligibility verification must identify whether coverage is traditional Medicare or an Advantage plan, and if the latter, which one. That is a different question from "is Medicare active", and it is the question that prevents most of these.

Growth in Advantage enrollment means a practice's Medicare book is steadily becoming a commercial book with a Medicare label. Processes built when most Medicare was traditional need revisiting on that basis alone.
