Medicare Part A vs Part D Billing Risks – How to Protect Your Claims
Pharmacies continue to receive PBM audit notices for claim recoupments where the [allegedly] improper Medicare coverage was billed. Medicare Part A helps cover hospital, skilled nursing facility (SNF), and hospice care stays. Medicare coverage status is typically linked to the patient’s admission and discharge dates from a Part A stay.
When a patient is covered under a Part A stay, the facility providing the stay is typically paid a per diem for the medications, supplies, and services needed during the coverage period. This means that Medicare Part D cannot (and will not) be responsible for claims billed during that time. Unfortunately, PBMs typically do not have the information at the point of sale to stop these claims from being billed inappropriately, leaving pharmacies scrambling upon retrospective review/audit.
PAAS Tips:
- Work with your contracted facilities to have a process in place for them to notify you of a patient’s Medicare status change
- Have an agreement in place, with the facilities you service, on how payments can be settled if claims were incorrectly billed to Medicare Part D and subsequently recouped
- Medications billed to Part D but delivered to facilities when a patient is “in-patient” (under a Part A stay) should be returned to the pharmacy (or rebilled accordingly)
- Per the Medicare Benefit Policy Manual claims can be billed once again to Part D on the day of discharge (see also SCC = 57 below)
- Any sooner and the claim would face full recoupment – even if there is only one day of overlap
- Stay informed for delays of patient discharge – if the patient has not left the hospital or SNF prior to their checkout time, the Part A facility may charge the beneficiary for another day of stay
- Questions asked during medication pick up may assist pharmacies on knowing if, or when, the patient will be discharged
- LTC patients’ medications may need to be split-billed when the patient is moved from a Medicare Part A to Part D stay
- Using submission clarification code 19 (Split-Billing) indicates the remainder of the claim being billed is no longer eligible under Medicare Part A stay. This code should only be used in an LTC setting.
- Using submission clarification code 57 (discharge medication) indicates the dispensed medication is for a patient’s discharge from a facility.
- If you receive a notice from Medicare D for incorrect billing due to a Medicare Part A stay, send it to PAAS National® for guidance
