Medicare Bad Debt Recovery 101

What Is Medicare Bad Debt?

Medicare bad debt refers to the unpaid deductible and coinsurance amounts owed by Medicare beneficiaries that hospitals and other providers have been unable to collect despite reasonable collection efforts. Under CMS regulations (42 CFR §413.89), hospitals can claim these uncollectible amounts on their Medicare cost report for partial reimbursement — typically at 65% of the allowable bad debt amount for most hospitals.

CMS Requirements for Medicare Bad Debt Claims

To qualify for Medicare bad debt reimbursement, hospitals must meet specific CMS criteria:

• The debt must be related to covered services — only Medicare-covered services with applicable deductibles and coinsurance qualify
• Reasonable collection efforts must be documented — CMS requires evidence of genuine, consistent collection attempts before declaring bad debt
• The debt must be actually uncollectible — hospitals must demonstrate they've exhausted reasonable collection methods
• Sound business judgment must be applied — the provider must have determined the debt is worthless and uncollectible
• The amount must be charged off the books — the bad debt must be written off to the organization's bad debt expense account

What Constitutes "Reasonable Collection Efforts"?

CMS defines reasonable collection efforts as those similar to efforts a provider would make for non-Medicare patients. Key requirements include:

• Multiple contact attempts — at least three patient contact attempts via phone, mail, or other channels
• Statement issuance — regular patient statements showing the balance due, typically at 30-day intervals
• 120-day minimum effort — collection efforts must span at least 120 days from the first billing statement
• Documentation retention — detailed records of every collection attempt, patient response, and outcome
• Indigence determination — for dual-eligible (Medicare/Medicaid) patients, Medicaid eligibility documentation substitutes for collection efforts

Common Medicare Bad Debt Mistakes

Even well-intentioned hospitals make errors that reduce their Medicare bad debt reimbursement. These mistakes often stem from disconnects between clinical operations, billing departments, and external collection partners. A single documentation gap on a sample account during a MAC audit can result in extrapolated denials across your entire bad debt portfolio — turning a minor oversight into a six- or seven-figure financial impact. The most frequent errors include:

• Insufficient documentation — MAC auditors frequently deny claims due to incomplete collection effort records
• Premature write-off — declaring bad debt before completing the required 120-day collection period
• Missing indigence documentation — failing to properly document Medicaid eligibility for dual-eligible patients
• Including non-covered services — claiming bad debt for services that don't qualify under Medicare coverage
• Inconsistent processes — applying different collection standards to Medicare vs. non-Medicare patients raises audit flags
