Laboratory Developed Tests (LDT)
TRICARE approves coverage for LDTs to inform and support clinical decision making in the care of our beneficiaries.
Prior authorization requirements
Prior authorization is required for all LDTs except for Cystic Fibrosis (CF) carrier screening and Noninvasive Prenatal Screening for Trisomies, 13, 18, 21, X & Y (NIPT) testing. Note: Expanded NIPT is not covered.
Providers must submit a completed LDT request and attestation for prior authorization and claims payment consideration. CF and NIPT testing, when part of the newborn screening panel, is handled under the global maternity authorization. For the quickest processing to approval for prior authorization, submit the request via provider self-service and attach the required documentation.
Please note that a completed attestation form will be accepted in lieu of supporting clinical documentation for prior authorization requests and claim payment; however, the authorizations are subject to a routine audit that will include a request to provide supporting medical documentation.
For all requests:
- Include the coverage criteria from the approved LDT list found on Health.mil to support your request
- Include complete beneficiary information, diagnoses, CPT codes for the requested tests and the purpose for the testing when requesting prior authorization
- Providers requesting one of the covered LDTs must use a CLIA-certified laboratory
- We suggest using Quest or LabCorp to ensure availability of an appropriately licensed lab
Given the complexity of risk assessment and test interpretation, as well as the importance of adequate medical management, genetic counseling is very valuable to any individual receiving a LDT. Genetic counseling may only be provided by TRICARE-authorized providers and must precede the actual LDT.
Beneficiaries are responsible for the appropriate copay/cost-share on lab claims processed with the approved authorization on file according to their benefit plan. Claims for genetic testing submitted without an approved authorization or LDT request and attestation form will be denied. Other Health Insurance (OHI) rules apply.
