Timely Filing
Providers have one year from the date of service to submit a claim to Medicare. To be considered timely, the claim must make it to the payment floor. Claims submitted can either be accepted or rejected by the payer.
If accepted, the claim may either pay or deny. An accepted claim will appear on the remittance advice where additional messaging will indicate if the claim paid, applied to deductible, or denied. Denied and unprocessable claims do not make it to the payment floor.
- If the claim denied, submit a reopening request to adjust a minor clerical error or submit an appeal with documentation to dispute the original decision.
- If the claim is unprocessable, correct the errors and resubmit within the one-year timeframe.
If rejected, the claim does not enter the claims processing system due to missing or invalid data and does not make it to the payment floor. The claim must be resubmitted with the corrected information within the one-year timeframe.
The Code of Federal Regulations (CFR), Title 42, Chapter IV, subsection 424.44, requires all claims for Medicare services furnished on or after January 1, 2010, to be filed with the Medicare Administrative Contractor (MAC) no later than one calendar year (12 months) from the date of service (DOS), or Medicare will deny the claim.
- In general, start date for determining one-year timely filing period is DOS or "From" date on claim
- Claims with a February 29 DOS must be filed by February 28 of following year to meet timely filing requirements
- For institutional claims that include span DOS (i.e., a "From" and "Through" date on claim), "Through" date on claim is used for determining DOS for claims filing timeliness
- For claims submitted by physicians and suppliers that include date spans, the "From" date is used to determine date of service for timeliness
A claim denied due to timely filing does not have appeal rights. See the CMS Internet Only Manual (IOM), Publication 100-04, Medicare Claims Processing Manual, Chapter 1, Section 70.
Medicare regulations, 42 CFR 424.44, allow that where a Medicare program error causes the failure of a provider to file a claim for payment within the time limit in section 70.1, the time limit will be extended through the last day of the sixth calendar month following the month in which the error is rectified by notification to the provider or beneficiary.
If a claim is denied for timely filing as the result of an administrative error due to a government agency, such as a Medicaid agency recouping money due to Medicare entitlement by the patient at the time of the service or an error with the patient's Social Security Administration (SSA) entitlement, the claim(s) may be resubmitted with a comment in Item 19 of the CMS-1500 claim form (or electronic equivalent) that indicates there was an administrative error. The comment in Item 19 for Medicaid recoupments should state "Medicare Buy Back" and for SSA retroactive entitlements, the comment should state "SSA Error-Retroactive Entitlement."
Paper claims should include a copy of the letter that indicates the date range for the claims involved or the effective date of the Medicare entitlement. Claims must be submitted by the last day of the sixth calendar month following notification that the error has been corrected by the government agency. The timely filing limit cannot be extended beyond December 31 of the third calendar year after the year in which the services were furnished. (For services furnished during October - December of a year, the time limit may be extended no later than the end of the fourth year after that year.)
