Denial Management
Timely Filing Limits by Payer Type: What Teams Should Track
Track timely filing by Medicare, Medicaid, and commercial payer type so denial teams protect recoverable balances.
Timely-filing denials are uniquely painful because the clinical work is done and the appeal path may already be closed. Limits differ by Medicare, Medicaid fee-for-service, Medicaid managed care, and commercial contracts. Denial teams need a payer-type reference—not a single tribal-knowledge number—before prioritizing aging work.
Treat timely filing as a calendar control, not a rumor
Every denial and A/R queue should expose remaining filing or appeal days where known. Staff should not rely on memory of “ninety days for everyone.” Maintain a living reference by payer type and major contract, and require written confirmation when a payer cites a different limit during a call.
Medicare filing windows and documentation habits
Medicare claims generally follow CMS filing rules with limited exceptions. Teams should know the baseline window and the documentation needed if an exception is asserted. Waiting for perfect coding on a Medicare claim that is approaching the filing limit is a common self-inflicted write-off.
Medicaid fee-for-service versus managed-care differences
State Medicaid fee-for-service systems and managed-care plans often publish different operational timelines. North Carolina’s NCTracks guidance, for example, is not automatically the same as a Standard or Tailored Plan’s portal rules. Verify the member’s program on the date of service before assuming one statewide clock.
Commercial contracts can be stricter than government baselines
Commercial timely-filing terms are contractual. A plan may allow less time than Medicare even for similar services. When onboarding a new payer contract, extract the filing and appeal language into the denial team’s reference file. Missing that step creates avoidable timely-filing concentration later.
Corrected claims and appeals use different clocks
A corrected claim deadline and a formal appeal deadline are not always identical. Review remittance language and payer policy before choosing the path. Spending the appeal window on an unchanged resubmission can exhaust rights without addressing the root cause.
Prioritize queues by remaining days and recoverability
A smaller balance with seven days left can outrank a larger balance with months remaining. Combine deadline risk with documentation availability and denial category. Timely-filing prevention also includes clean-claim focus areas that stop claims from sitting unbilled while calendars run.
Report timely-filing denials as their own category
If timely filing is buried inside a generic denial bucket, leadership cannot see whether the issue is slow charge capture, stalled enrollment, or weak follow-up. Separate the category, assign an owner, and measure whether process changes reduce new timely-filing losses.
