A home health therapy visit can draw the same scrutiny as any Medicare audit defense matter: can the record prove a qualified therapist's skill, not a therapist's presence, was required. A Recovery Audit Contractor (RAC), a Unified Program Integrity Contractor (UPIC), or a Medicare Administrative Contractor (MAC) can pull a sample of physical therapy, occupational therapy, or speech-language pathology visits from a home health episode and extrapolate any finding across the lookback period. The line a reviewer tests is narrow: skilled therapy versus a maintenance program, and whether a therapist, not an assistant, reassessed the patient on schedule.
Skilled Therapy Versus a Maintenance Program
Medicare's home health benefit covers skilled therapy when a service's complexity requires a physical therapist, occupational therapist, or speech-language pathologist to perform it safely and effectively, not because the patient's diagnosis sounds severe. The Medicare Benefit Policy Manual, chapter 7, section 40.2.1, sets three paths to coverage: a therapist's skill is needed to restore function, with material improvement expected within a reasonable and predictable period; a therapist's skill is needed to design a maintenance program, ordinarily during the last restorative visits; or a therapist's skill is needed to safely carry out that maintenance program because the patient's own medical complications make an otherwise unskilled service too risky for unskilled hands. General exercise for overall fitness, or visits that provide only motivation, satisfy none of the three paths and are not billable as skilled therapy.
The 30-Day Reassessment a Therapist Must Perform
For each therapy discipline billing under the plan of care, a qualified therapist, not an assistant, must personally perform an initial functional assessment using an objective measurement of activities such as walking, bathing, dressing, or using assistive devices, and document the result. At least once every 30 days after that first visit, that discipline's qualified therapist must personally furnish the ordered visit, functionally reassess the patient, compare the new measurement to the prior one, and document the comparison and a conclusion on whether the therapy is working. The 30-day clock starts with the discipline's first treatment visit and resets each time its therapist completes a reassessment visit. A claim where only an assistant performed the visit due for reassessment is missing the service Medicare paid for.
What a Reviewer Flags in the Visit Notes
CMS has told contractors what does not count as documentation of skilled care. A note stating only that the patient tolerated treatment well, that a caregiver was instructed in medication management, or to continue with the plan of care describes nothing a reviewer can measure. A compliant note carries the objective measurement taken that day, the patient's response to the service furnished, and the plan for the next visit based on that response. When the service maintains function rather than restores it, the note also needs a rationale explaining why the patient's own medical complications, not the service alone, required a therapist's skill to perform it safely.
From a Documentation Gap to an Extrapolated Recoupment
Extrapolation applies the sample's error rate to every home health claim in the lookback period, turning a pattern of assistant-led reassessments or boilerplate notes into a recoupment many times the size of the sample itself, sometimes measured against a local coverage determination's own required elements. The overpayment demand is only the first procedural step. An agency that disputes the finding can pursue Medicare Redetermination: Winning at Level One. A pattern serious enough to threaten billing privileges can also carry the exposure covered in Medicare Reenrollment Bars: How Long You Are Out, and getting the paperwork right afterward is the subject of Medicare Revalidation: Getting It Right the First Time.
Coverage of home health therapy turns on the patient's need for a therapist's skill, not on whether the patient's condition can still improve.
Why Early Legal Counsel Is Critical
It is critical that home health providers promptly retain experienced healthcare defense counsel upon receiving a RAC, UPIC, or MAC additional documentation request (ADR), or any other government inquiry. Early legal intervention can protect the provider's rights, help shape appropriate responses to government requests, avoid inadvertent admissions, preserve relevant defenses, and allow counsel to communicate with investigators on the provider's behalf. Delaying legal representation can significantly affect the outcome of a matter and expose the provider to unnecessary risk.
