What Medicare reviewers actually check in therapy documentation

When a Medicare Administrative Contractor, RAC auditor, or state surveyor opens a therapy chart, they are not reading it the way a clinician does. They are running a checklist, and in documentation reviews, denied claims and recoupment demands trace back to checklist items the record failed.

Skilled Nursing Facility (SNF) therapy documentation is evaluated against a surprisingly stable set of questions. Here is the practical map: what each question asks, and what “failing it” looks like in a real chart.

Where most money is lost

Medical necessity. Does the record support that skilled care was necessary for this resident, this week? “Resident tolerated treatment well” is the classic failure: it describes attendance, not necessity. The standard, rooted in 42 CFR §409.32 and reinforced by Jimmo v. Sebelius, is that skilled care can be justified by the need to maintain function, not only to improve it, but the documentation must actually make that case.

The same record has to answer the closely related question of why the intervention required a therapist rather than a caregiver or restorative aide. Notes that describe what was done without why it took a licensed clinician fail on that ground.

Plan of care compliance. The plan says three visits per week for 4 weeks; the record shows 5 visits one week and 2 the next, with no order change. Frequency, duration, and intensity in the documentation must match the certified plan, and the certification dates must cover every visit billed.

Timeliness. Evaluations completed within the required window, Medicare Part B progress reports on their treatment-day clock, recertifications signed before the period lapses (delayed certifications are allowed only with a documented, acceptable reason per the Benefit Policy Manual). Documentation that misses its window with no compliant cure is treated as missing.

Quality of the clinical record

Goal quality. Goals must be measurable, functional, and time-bound. “Improve transfers” fails; “resident will complete bed-to-wheelchair transfer with contact-guard assist within 2 weeks” passes.

Reporting on progress toward those goals runs on a clock that depends on the payer. Under Medicare Part B, the required progress report is written by the therapist (not the assistant) on its treatment-day interval. Medicare Part A SNF stays run on a different clock — the MDS assessment schedule plus physician certification and recertification under 42 CFR §424.20 — and non-Medicare payers set their own.

Beyond those, reviewers weigh the quality of the record itself — whether measurements are objective, whether the disciplines agree with each other and with the MDS, whether the chart can stand alone without verbal explanation — and the payment-system consistency behind it.

Payment-system consistency

Under the Patient Driven Payment Model, the clinical record has to support the case-mix classification that was submitted, with diagnoses, function scores, and the therapy actually delivered all telling the same story. The billed minutes and visit pattern have to be clinically coherent with the documented condition, too: a flat, identical minutes pattern every week for every resident is a pattern reviewers notice.

Authentication carries the same weight as content. Notes need the right credential, in the right order, at the right time, and reviewers treat unsigned notes and missing co-signatures as findings. Backdated signatures are prohibited outright (Program Integrity Manual), though properly labeled late entries, addenda, and corrections that meet the applicable requirements remain permitted. Assistants, in turn, may document and perform only what their license and state practice act allow, with evaluations always by the therapist.

The rest of the chart

Reviewers also read for the things a chart reveals about the care around it: whether the resident’s engagement and refusals were documented and followed up, whether precautions were observed as well as recorded, and whether therapy reads consistently alongside nursing and physician documentation. The record has to account for the end of the episode as well as the middle, with status against goals, disposition, and recommendations at discharge.

Fraud, waste and abuse safeguards. The integrity checks look for cloned notes, inflated minutes, and fabricated entries. The through-line is simple: every claim in the note has to be supported, and every date has to hold.

Why manual audit programs miss these

Not because auditors don’t know the rules. Because arithmetic is against them. A conscientious internal auditor covers a handful of charts per day. A 100-bed facility generates thousands of pages of documentation a month. Sampling is the only coping strategy, which means most documentation is never reviewed by anyone before a payer reviews it.

The failure modes follow directly: findings depend on who audited, feedback reaches therapists weeks after the note was written (if ever), and the same issues recur because nothing connects audit results to training.

What good looks like now

Facilities are increasingly moving to 100% audit coverage: every document checked automatically as documentation is created, with findings that carry their evidence (document, page, section) and their regulatory citation, assigned to a person, and tracked to resolution. The role of the human compliance professional shifts from sampling charts to managing a program: reviewing findings, prioritizing them, and closing the loop through targeted training.

That last step matters most. An audit that finds the same “goal lacks baseline” finding every month is measuring a training problem. The programs that work treat every recurring finding as a curriculum item, which is exactly how the audit-plus-coaching loop in CareDocs.ai Compliance Agent is designed.
