Medicare hospice audits increasingly turn on one clinical judgment: whether a patient's prognosis genuinely supports a life expectancy of six months or less. The Centers for Medicare & Medicaid Services (CMS) and the Department of Health and Human Services Office of Inspector General (OIG) have identified long lengths of stay and live discharges as the clearest signals of hospice eligibility abuse, and Medicare's audit contractors build review programs around those signals. A hospice that cannot show an individualized clinical basis for its prognosis certifications faces extrapolated overpayment demands on the audited claims and, separately, faces repayment exposure under the hospice aggregate cap regardless of whether any single claim is ever challenged.

Certifying a Six-Month Prognosis

Under 42 CFR 418.22, a hospice election requires written certification that the individual's prognosis is for a life expectancy of six months or less if the terminal illness runs its normal course. For the initial 90-day benefit period, both the hospice medical director, or physician designee, and the patient's attending physician, if one exists, must certify; later periods require only the hospice physician. Starting with the third benefit period and every recertification after it, a hospice physician or nurse practitioner must also complete a face-to-face encounter with the patient, no more than 30 days before the recertification, to gather the clinical findings supporting continued eligibility. The certifying physician must attach a brief narrative explaining the clinical findings behind the prognosis, and CMS requires that narrative to reflect the patient's individual circumstances rather than a checkbox or standard language used for every patient. Some Medicare Administrative Contractors publish Local Coverage Determinations describing the measurable indicators of decline they expect documented for common terminal diagnoses; a narrative that recites the diagnosis without those indicators is the most common basis for a hospice eligibility denial.

Long Length of Stay and Live Discharge as Audit Triggers

OIG's hospice program vulnerabilities portfolio identified documentation errors, live discharges, and lengths of stay beyond six months as recurring red flags in hospice program integrity reviews. CMS compares a hospice's long-stay caseload and live-discharge rate against its peers, and an outlier result is typically what triggers an additional documentation request (ADR) from the hospice's Medicare Administrative Contractor. From there, a poor sample response can escalate into a Targeted Probe and Educate review, a Recovery Audit Contractor (RAC) review, or a full medical review, and, if the findings are poor enough, into a statistical extrapolation across the hospice's full claims universe; our breakdown of the Medicare audit process covers those stages in more detail. A heavier long-stay population is not automatically noncompliant, but it carries a heavier documentation burden at every recertification, since the record has to keep showing continued decline, not just the original diagnosis.

A hospice can survive every individual claim review and still owe Medicare a refund under the aggregate cap, because the cap measures total per-beneficiary payments against a fixed dollar ceiling, not the merits of any single terminal-illness certification.

The Hospice Aggregate Cap Under 42 CFR 418.309

Separate from any claim-level eligibility dispute, 42 CFR 418.309 caps the total Medicare payments a hospice can receive in a cap year. The aggregate cap is a fixed per-beneficiary dollar amount multiplied by the number of Medicare beneficiaries the hospice served that year; CMS set the cap at $35,361.44 for the cap year running October 1, 2025 through September 30, 2026, up from $34,465.34 the year before. Under 42 CFR 418.308, payments above the cap are overpayments the hospice must refund, and it must file its self-determined cap calculation within five months of the cap year's close or risk having its payments suspended. Because the cap runs on total per-beneficiary payments rather than any individual claim, a hospice with many long-stay patients can owe a refund even when every certification in the file is defensible on its own terms.

Why Early Legal Counsel Is Critical

It is critical that hospices retain experienced healthcare defense counsel promptly upon receiving an additional documentation request, a Unified Program Integrity Contractor audit notice, or a cap liability determination. Early legal intervention can protect the hospice's rights, ensure the certification narratives and face-to-face attestations already in the record are presented accurately, avoid inadvertent admissions in a written response, and preserve the hospice's appeal rights at every level. Delaying legal representation can significantly affect the outcome of a matter and expose the hospice to unnecessary financial risk.
