What Is a Medicare ADR Letter? A Complete Guide for Hospice Agencies
Table of Contents
Receiving an Additional Documentation Request (ADR) from a Medicare Administrative Contractor (MAC) can be a stressful moment for hospice administrators. An ADR indicates that Medicare has selected a claim for review and requires additional clinical documentation before confirming payment.
In today's regulatory environment, managing ADRs effectively is no longer just a billing responsibility. It is a critical part of hospice compliance management, revenue protection, and audit readiness.
Understanding how the Medicare ADR process works can help hospice agencies respond efficiently, avoid denials, and maintain compliance with Medicare requirements.
What Does ADR Stand for in Medicare?
In Medicare billing and auditing, ADR stands for Additional Documentation Request.
It is a formal request issued by a Medicare Administrative Contractor (MAC) asking healthcare providers to submit medical records supporting a specific claim.
These records are used to verify that the services billed meet Medicare's medical necessity, documentation, and coverage requirements.
ADR requests are commonly issued during pre-payment and post-payment claim reviews.

Before evaluating clinical eligibility, Medicare reviewers verify technical compliance.
Important documents include:

Level 2 – Clinical Eligibility Review
If technical requirements are satisfied, reviewers assess whether the documentation supports hospice eligibility.
They evaluate indicators such as:
The documentation must clearly support a prognosis of six months or less.
