Medicare Skilled Nursing Facilities Bad Debt Compliance Update

Medicare SNF bad debt remains one of the last dependable cost‑report reimbursement opportunities, but CMS and the MACs continue to tighten oversight. Audit outcomes are increasingly binary: documentation either meets CMS standards, or the claim is fully disallowed. In this newsletter we will summarize the rules, risks, and internal controls every SNF should have in place.

Allowability of Medicare Part A bad debt

A Medicare Part A bad debt is allowable only when all four of the following criteria are met:

• Balance relates solely to deductible and coinsurance amounts for Medicare covered services
• Reasonable collection efforts are fully documented
• No likelihood of future recovery based on sound business judgment
• The debt was not reimbursable by another payer

A standardized checklist that verifies each of the four Medicare bad debt criteria is met serves as a critical tool for effective audit defense.

Timeliness: First Bill Within 120 Days

CMS requires the beneficiary be billed within 120 days of the latest triggering event (i.e., Medicare RA, secondary RA/denial, or a notice indicating secondary coverage does not apply). Late first billing remains one of the most common MAC recoupment triggers.

Suggested Revenue Cycle Control Measures:

• Automate billing on RA posting
• Timestamp all billing events
• Prevent bad‑debt write-offs until 120‑days after first bill date

Reasonable Collection Effort

PRM‑I §310 requires Medicare beneficiaries to be pursued at least as aggressively as non‑Medicare patients with equivalent debt. Audit‑safe documentation includes:

• Timely initial bill
• Follow‑up statements
• Collection letters or agency referral

Outstanding amounts cannot be written off while still in active collections.

Dual‑Eligible Crossover Requirements

For dual‑eligible residents (individuals who qualify for both Medicare and Medicaid), Medicare bad debt can only be claimed after Medicaid has adjudicated the crossover claim and issued a remittance confirming either (1) payment of Medicare cost‑sharing or (2) that state‑specific limits prevent payment. This requirement is explicitly reinforced in CMS and MAC guidance.

Timely billing matters:

• VA Medicaid FFS: must be billed within 6 months of receiving the Medicare RA
• VA Medicaid MCOs: must be billed within 12 months of receiving the Medicare RA

Medicaid FFS claims expire faster and should be prioritized.

Write‑Off Accounting Precision

Medicare bad debt must be recorded as a true bad debt expense rather than a contractual allowance. This distinction shows that the unpaid deductible or coinsurance is an uncollectible patient responsibility, not a negotiated payer adjustment. Clear separation in the general ledger helps maintain accurate cost reporting and prevents confusion during audits.

• Misclassification is a common MAC audit recoupment trigger.
• Auditors review GL accounts, write‑off codes, and mapping to ensure bad debt is segregated and consistently applied.
• Incorrect categorization is a key CMS focus area key CMS focus area during desk reviews and field audits.

Accounting Period: Claim in the Year the Write-Off Occurs

A Medicare bad debt must be claimed on the cost report for the period in which it was actually written off the provider’s books as worthless — not the period the service was rendered or the period collection efforts began. If an account isn’t written off until after a facility’s fiscal year end has already closed, it cannot be claimed retroactively on that closed cost report; it rolls forward and must be claimed on the next cost report instead.

• Align write-off timing with fiscal year end during quarterly bad debt reviews, so accounts nearing the 120-day mark late in the fiscal year aren’t left stranded in the wrong cost reporting period.
• Confirm the Write-Off Date on the CMS bad debt listing matches the GL posting date, not the date the account was first flagged as delinquent.
• Facilities with a cost report year end that doesn’t align with the calendar year should build in extra lead time to finalize write-offs before close, rather than defaulting to a calendar year-end cutoff.

Mandatory CMS SNF Bad Debt Listing

All claimed accounts must appear on the CMS template, with the following information:

The bad debt amounts and supporting details on the log must fully reconcile to both the general ledger and the A/R aging. The listing should tie out to the exact write‑off amounts recorded in the GL, and every account included must appear in the aging with dates, balances, and statuses that match the documentation.

Internal Controls That Survive Audits

High‑performing SNFs maintain:

• Written policy mapped to CFR and PRM
• Quarterly bad‑debt reviews by an internal audit team to validate documentation, timeliness, and compliance
• Revenue cycle and reimbursement teams sign‑off on all write-offs after verifying supporting documentation

Common recoupment triggers that must be avoided.

• First bill issued after 120 days
• Accounts still in active collections
• Missing Medicaid RA for dual‑eligibles
• Bad debt booked as contractual allowance
• Unequal collection effort
• Incomplete CMS bad‑debt listing

Bottom Line

When executed correctly, Medicare SNF bad debt is fully compliant, audit‑defensible, and reimbursable at 65% of Part A deductible and coinsurance. Strong controls and precise documentation remain the key to protecting this valuable reimbursement stream.nd precise documentation remain the key to protecting this valuable reimbursement stream.
