Billing for Services when Medicare is a Secondary Payer

Medicare Secondary Payer

Background

Medicare law and regulations require all entities that bill Medicare for services or items given to Medicare beneficiaries to decide whether Medicare is the primary payer for those services or items before submitting a claim to Medicare. (See Section 1862(b)(2) of the Social Security Act and regulations at 42 CFR 489.20g.)
When you find another insurer as the primary payer, bill that insurer first. (Page 16 of Chapter 3 of the Medicare Secondary Payer Manual provides guidance on finding other primary payers.) After receiving the primary payer remittance advice, bill Medicare as the secondary payer, if appropriate.

If you see a beneficiary for multiple services, bill each service to the proper primary payer. Recently, there have been situations where we have inappropriately denied L, NF, or WC MSP claims when you provided services that are not related to the accident or injury identified on the beneficiary’s Medicare record.

If you believe Medicare inappropriately denied a claim, do the following

  • Check your claim to make sure you submitted a correctly completed claim to the proper payer(s).
  • Contact your MAC.
  • File an appeal if necessary. (An appeal and a phone call to the MAC is the most efficient method for resolving an inappropriately denied claim.)
  • Give information to your MAC that shows the inappropriate denial.
  • Tell your MAC that the service performed isn’t related to the accident or injury on record, the reason why it’s unrelated to the accident or injury, and request that Medicare adjust and pay the claim if it’s a Medicare covered and payable service.
  • Don’t instruct Medicare beneficiaries to contact the Benefits Coordination and Recovery Center (BCRC) to delete the open MSP record. In many situations, the
    open record may be an active record that shouldn’t be deleted.
  • Don’t bill the Medicare beneficiary for the inappropriately denied claims or refer the claims to a collection agency. Resolve the claims issue with your MAC.

Key Reminders

  • Collect full beneficiary health insurance information upon each office visit, outpatient visit, and hospital admission.
  • Find the primary payer before submission of a claim, and bill the proper responsible payer(s) for related services.
  • Check Medicare Eligibility to identify accident or injury diagnosis codes for L, NF, or WC MSP periods.
  • For multiple services, bill each responsible payer(s) separately.
  • If you give treatment to a beneficiary for accident-related services and non-accident-related services, don’t submit both sets of services on the same claim to Medicare. Send separate claims to Medicare: one claim for services related to the accident and another claim for services not related to the accident.
  • You should always use specific diagnosis codes related to the accident or injury. Doing so will promote correct and prompt payments.
