Medical Services Account

Medical Services Account (MSA) activities involve billing and collecting funds for medical and dental services, including elective cosmetic procedures, provided in the Defense Health Program (DHP) fixed facilities from the following entities:

  • DoD beneficiaries;
  • Other government agencies;
  • DoD civilians and contractors;
  • Non-Appropriated Fund (NAF) employees;
  • Secretarial Designees;
  • Authorized foreign military members;
  • DoD dependent school employees; 
  • Army and Air Force Exchange Services (AAFES) employees;
  • Civilian emergency (CE) patients; and
  • Other non-DoD beneficiary patients authorized to receive treatments in MTFs.

The rates used for MSA billing are included in the Inpatient Adjusted Standardized Amounts (ASA) and Outpatient rate packages approved annually by the Assistant Secretary of Defense for Health Affairs. The billed amount is based on patient category and eligibility (PATCAT) at the time the care is rendered. The Defense Enrollment Eligibility Reporting System (DEERS) is the official site for determining eligibility for most patients. 

Funds collected through MSA are used to enhance health care delivery at the MTF providing the care.
