Question: We had a problem with a claim and didn't get it filed with Medicare until over a year after the procedure date. Will this get paid? Codify Subscriber Answer: No. Medicare gives you only 12 months to file a claim, and exceeding this limit will cause instant denials. The time period for filing Medicare fee-for-service claims was amended as part of the Patient Protection and Affordable Care Act. Under this law, the claims for services furnished on or after Jan. 1, 2010, must be filed within one calendar year after the date of service. Medicare requires all providers, both participating or non-participating, to submit the claim to Medicare on behalf of the beneficiary. This includes submitting those claims on a timely basis. Lose pay: Medicare considers claims not submitted on time as 'provider liable,' meaning you cannot charge the beneficiary for those services. There are some limited exceptions to the one-year filing rule, which include administrative error and retroactive Medicare entitlement.
