Maryland Medicaid Billing
(including Medicaid Managed Care Providers in Maryland)

The following documents are required to bill Maryland Medicaid.  We are not able to bill any Medicaid program outside of Maryland.  

All required items must be received prior to test initiation.

 Copy of patient's insurance or Medicaid card, front and back

 Letter of medical necessity from referring physician

 If 18 or older, copy of driver's license or photo ID

 Physician referral or prescription for testing
 Billing Consent Form

A note about the new CPT codes for 2013:
As many of our tests for rare diseases will be using the unlisted code (81479), we anticipate an increase in denials of coverage.  Verification of coverage of the test codes is required, and patients should be informed of the possibility of Medicaid denials.
