Medication-Assisted Treatment (MAT) Billing: Coding and Reimbursement

Medication-Assisted Treatment (MAT) Billing: Coding and Reimbursement

Medication Assisted Treatment (also known as medications for Opioid Use Disorder or MOUD) is the use of medications to treat Opioid Use Disorders (OUDs), such as Buprenorphine or Suboxone. There has never been a reimbursement model for MAT in the emergency department (ED). In response to ACEP advocacy, CMS finalized its proposal to pay for MAT provided in the emergency department beginning in 2021.

Patients may obtain MAT in various settings, such as outpatient physician offices or clinics; opioid treatment programs (OTPs), residential facilities, and hospitals. The proper billing and coding for MAT services are determined by the treatment setting, the services given, and the diagnosis.

Let’s have a look at the coding guidelines related to Medication Assisted Treatment (MAT):

HCPCS Codes

Undoubtedly, accurate coding is critical for claims submitted to third-party payers since incorrect codes can misrepresent the patient care, obstruct research to improve patient care, and result in revenue loss for the hospital. Thereby, HCPCS codes (Healthcare Common Procedure Coding System) are used by Medicaid, Medicare, and other health insurance systems to ensure that insurance claims are processed in an organized and consistent manner. Also, the HCPCS Coding System is required for:
  • Hospital payments
  • Physician reimbursement
  • Quality review
  • Measuring benchmarks
The following are the HCPCS codes used for Medication Assisted Treatment (MAT) billing:

Outsource MAT Billing & Coding:

You can also use weekly billing cycles that vary according to the patient. The first day of service will be determined by the day of the week the patient is admitted to the program or when Medicare begins billing. When a patient starts treatment or resumes treatment after a break in treatment, the date of service is the first day you see the patient.
