ADR (Additional Documentation Request)
An Additional Documentation Request (ADR) is a formal request from a Medicare review contractor, most often the Medicare Administrative Contractor (MAC), asking a provider to submit medical records that support a claim selected for review. For home health agencies, an ADR typically requires the plan of care, face-to-face documentation, OASIS, visit notes, and orders. Missing the response deadline, generally 45 days for MAC reviews, results in an automatic denial.
Why ADRs matter for home health agencies
An ADR is the mechanism behind most Medicare medical review: Targeted Probe and Educate (TPE) rounds, Review Choice Demonstration (RCD) postpayment options, Supplemental Medical Review Contractor audits, and Unified Program Integrity Contractor (UPIC) investigations all arrive as document requests. The claim's fate rests entirely on what the agency sends back. Payment is suspended while a prepayment ADR is pending, so slow responses directly stretch cash flow. And because reviewers judge only the paper in front of them, care that was delivered but poorly documented is treated the same as care that never happened. High ADR denial rates also feed provider risk scores, inviting more review.
How the ADR process works
For a prepayment ADR from the MAC, the claim moves to a hold status and the request is issued. In home health, billers typically catch ADRs by monitoring claim status in the Direct Data Entry (DDE) system, since mailed notices can lag. The agency generally has 45 days to submit records; if nothing is received, the claim denies automatically for non-response. Once records arrive, the reviewer typically has about 30 days (for prepayment review) to decide. Denials can be appealed through the standard five-level Medicare appeals process, starting with redetermination by the MAC within 120 days.
What a complete home health ADR response includes
Reviewers deny most home health claims for eligibility documentation gaps, not visit quality. A complete packet usually includes:
- Signed and dated plan of care and certification or recertification
- Face-to-face encounter documentation tied to the primary reason for home health
- OASIS assessment matching the billed HIPPS code
- All visit notes for the billing period, supporting skilled need and homebound status
- Signed physician orders, including verbal orders, covering all billed services
- Therapy evaluations and reassessments where applicable
Send everything the claim depends on, organized and legible, the first time. Appeals take months; a complete first response avoids them.
Common pitfalls
The classic failure is not knowing the ADR exists until day 30 because no one was checking DDE weekly. Others: sending records for the wrong billing period, omitting the face-to-face document or sending one that does not address the primary diagnosis, submitting unsigned orders, and treating the deadline as day 45 when mailing and processing time eat several days. Agencies with strong ADR outcomes assign clear ownership, track every request and due date on a log, run a QA review of the packet before it goes out, and study denial reasons to fix upstream documentation habits.
Frequently asked questions
How many days do I have to respond to a Medicare ADR?
For MAC prepayment reviews, including TPE, the standard is 45 calendar days from the date of the request. If no documentation is received, the claim is denied for non-response. Build in a buffer of at least a week for assembly, QA, and delivery.
What happens if my claim is denied after an ADR?
You can appeal. The first level is redetermination by the MAC, requested within 120 days of the denial. Many documentation denials are overturned when the missing piece is supplied, but appeals add months to payment, so a complete initial response is far cheaper.
Do ADRs only come from my MAC?
No. MACs issue the most ADRs, but the Supplemental Medical Review Contractor, Recovery Audit Contractors, and UPICs also request records. The source matters: a UPIC request signals a program integrity investigation and deserves immediate leadership attention, often with compliance counsel involved.
