  • Medical-Legal
  • Physician Dispensed DME
  • Physician Dispensed Pharmaceuticals (look up using CPT 99070)
  • California Specific Reporting Codes

Step 2. Enter ‘DOS’

An accurate OMFS reimbursement amount requires the Date of Service. OMFS reimbursement amounts are calculated using the fee schedule(s) in effect on the date the services were rendered. The Calculator stores historical reimbursement data for dates of service 2005 to present.
