ADR, in one sentence

An Additional Documentation Request (ADR) is a written notice from a Medicare Administrative Contractor (MAC) asking a hospice provider to submit medical-record documentation supporting a specific claim [1]. It’s not an accusation of wrongdoing — but it is a hard deadline, and the response quality determines whether the claim is paid, denied, or opens a Targeted Probe and Educate (TPE) round.

What triggers an ADR

ADRs are typically pulled from one of three lanes:

  • Statistical sampling — a MAC selects claims based on statistical thresholds (e.g. long lengths of stay, high-dollar claims, atypical patterns).
  • Targeted edits — a MAC flags a specific diagnosis, level of care, or documentation pattern for review.
  • Direct probe as part of TPE — the MAC opens a TPE round on your hospice and pulls 20–40 claims for review.

The 45-day clock

The provider has 45 calendar days from the date on the ADR letter to submit the requested documentation. Miss the deadline and the claim is denied automatically for “failure to respond” — no clinical review, no appeal at that stage, just a denial [2].

Most experienced hospice compliance officers treat the internal deadline as day 30, leaving 15 days of buffer for medical-director review, quality-control passes, and mailing/upload issues.

What a strong ADR response contains

Every ADR asks for specific documentation for a specific claim, but a strong response reliably contains:

  1. Certification of Terminal Illness for the applicable benefit period.
  2. Face-to-face encounter documentation (if applicable to the benefit period being reviewed).
  3. Plan of care with all IDG updates.
  4. Complete IDG meeting notes for the review period.
  5. All visit notes (RN, aide, SW, chaplain, therapies) for the review period.
  6. Medications list and any related orders.
  7. Physician orders for services and level-of-care changes.
  8. Election statement and any addenda.
  9. Documentation supporting the terminal prognosis — the narrative decline, comorbidities, functional/nutritional/cognitive indicators.

Cover letters that explicitly index the request against your submission (“requested item #4: pages 12–28”) speed up MAC reviewer decisions and reduce the chance of a denial for “insufficient documentation.”

How to prevent ADRs from becoming denials

  • Weekly ADR-readiness audit — pick 3 charts and pretend you got the letter.
  • Narrative decline in every visit note. If a MAC reviewer reads six weeks of visits and can’t see decline, the claim is at risk regardless of eligibility.
  • F2F narrative fully composed by the physician / NP — the top ADR-denial trigger.
  • IDG meeting notes that show plan revisions, not just attendance.
  • Chart-close hygiene at discharge — scrambled charts at review time are what actually cause denials.

Frequently asked questions

How long do I have to respond to a Medicare ADR?
45 calendar days from the date on the ADR letter. Miss the deadline and the claim is denied for failure to respond.
Does receiving an ADR mean my hospice did something wrong?
No. ADRs are a routine documentation-review mechanism. They can be part of routine sampling or a targeted edit; only the response outcome (paid or denied) reflects on the claim.
Can I appeal an ADR denial?
Yes. Standard Medicare appeal levels apply: redetermination, reconsideration, ALJ hearing, Medicare Appeals Council, and federal court. Deadlines are strict — start the redetermination process within 120 days of the initial denial.
What is the difference between ADR and TPE?
An ADR is a request for documentation on a single claim. TPE (Targeted Probe and Educate) is a structured MAC review that opens a probe of 20–40 claims across three rounds with education after each round.
How much documentation should I send?
Send everything the ADR explicitly requests, plus the anchor documents (certification, F2F, plan of care, IDG notes, visit notes, orders, and election statement). Do not send unrelated PHI.
