Medicare Administrative Contractors, Recovery Audit Contractors, and Unified Program Integrity Contractors are reviewing home health claims against four specific documentation points: homebound status, the physician face-to-face encounter, the certified plan of care, and the Outcome and Assessment Information Set (OASIS) assessment. A denial rarely turns on the quality of care delivered. It turns on whether the medical record, not only the home health agency's own notes, supports each element the way 42 CFR 424.22 requires. Physicians who certify home health eligibility carry documentation exposure that follows the claim long after the visit is complete.
The Two-Part Homebound Status Test
A patient qualifies as confined to the home only by meeting two criteria under CMS's Medicare Benefit Policy Manual, Chapter 7, Section 30.1.1. Criterion one requires that, because of illness or injury, the patient needs a supportive device, special transportation, or the assistance of another person to leave the residence, or has a condition that makes leaving home medically contraindicated. Criterion two requires both a normal inability to leave home and that leaving home takes a considerable and taxing effort. CMS has been explicit that repeating stock phrases such as "taxing effort to leave the home" does not, by itself, satisfy criterion two. Auditors expect longitudinal clinical evidence, tied to the specific patient's diagnosis, functional limitations, and clinical course, not boilerplate language reused across a caseload.
The Face-to-Face Encounter Requirement
The face-to-face encounter must occur no more than 90 days before the home health start of care date or within 30 days after it, and must be performed by the certifying physician, an allowed non-physician practitioner working with that physician, or a physician or practitioner who treated the patient in an acute or post-acute facility from which the patient was directly admitted. CMS requires that documentation of the encounter, and of homebound status and skilled need, live in the certifying physician's own medical record or the discharging facility's record, not only the home health agency's chart. Home health agency documentation can support certification only when the certifying physician incorporates it by signing and dating it, and only when it is corroborated by other entries in the physician's own record.
Plan of Care Certification and Recertification
Home health services are covered only under an individualized plan of care that a physician or allowed practitioner establishes, signs, and periodically reviews under 42 CFR 484.60(a). Recertification is required at least every 60 days for continuous care, and the Medicare Conditions of Participation at 42 CFR 484.55(d)(1) generally require the recertification assessment during the last five days of the prior certification period, days 56 through 60 of an initial 60-day certification. A signature obtained after an audit notice has already arrived corrects nothing. Repeated certification and recertification deficiencies can also feed into a broader Medicare billing privilege revocation review, extending the exposure well beyond the flagged claims.
OASIS Consistency and the Denials That Recur
Contractors, including Recovery Audit Contractors (RACs), compare the OASIS assessment against the plan of care and the clinical visit notes for internal consistency. An OASIS item scoring a patient as independent in a functional area while a nursing note describes moderate assistance is a recurring trigger for review, and generic homebound language repeated unchanged across multiple certification periods draws the same scrutiny. Once a contractor identifies this kind of pattern across a sample of claims, extrapolation applies the sample's error rate to the full lookback period, converting a handful of flagged episodes into a six-figure recoupment demand. Physicians facing that kind of finding should review our companion piece on when to engage a Medicare audit attorney, since the appeal window narrows quickly once the letter arrives.
A homebound certification that rests on the home health agency's notes alone, without corroboration in the physician's own chart, collapses on audit review.
Why Early Legal Counsel Is Critical
It is critical that physicians promptly retain experienced healthcare defense counsel upon receiving a home health audit notice, additional documentation request, or other government inquiry. Early legal intervention can protect the physician's rights, ensure the response addresses homebound status, the face-to-face encounter, and OASIS consistency together, avoid inadvertent admissions, and preserve defenses that may otherwise be lost. Delaying legal representation can significantly affect the outcome of the matter.
How Health Law Alliance Can Help
Health Law Alliance defends physicians and home health agencies against Medicare audits built on homebound status, face-to-face encounter, and OASIS documentation findings. Our bench includes a former federal prosecutor and a former senior healthcare compliance executive, background that shapes how we evaluate which flagged claims are defensible.
