Monitor payer policy activity
Governs prior authorization, medical necessity review, and genetic counseling requirements for germline and somatic genetic testing for CareSource members in the Arkansas PASSE program.
No material clinical or coverage changes in this revision.
Coverage and Medical Necessity Criteria
Coverage criteria
Covered when reviewed and approved per medical necessity determinations and MCG criteria as applicable:
Proprietary panels require evidence-based documentation; individual tests may be requested separately if panels do not meet medical necessity.
Somatic testing does not require this genetic counseling.
HLA typing is explicitly excluded from this genetic testing policy and does not require preauthorization under the CareSource genetic testing policy.
Proprietary multi-gene panels that do not meet medical necessity requirements per the Medical Necessity Determinations administrative policy may not be approved for coverage; in those cases, CareSource allows individual genetic tests to be requested and reviewed separately according to the Medical Necessity Determinations policy.

Provider Requirements and Prior Authorization
Prior Authorization Required
Prior authorization may be required for genetic testing (both somatic and germline). Lack of required prior authorization when prior authorization is required for genetic testing may result in claim denial. Providers should verify prior authorization requirements before ordering tests.
- Applies to somatic and germline genetic testing
- Denial risk if required prior authorization not obtained
Medical Necessity Review
CareSource will review genetic testing requests for medical necessity using published MCG criteria when available and the Medical Necessity Determinations administrative policy. Proprietary panel testing requires evidence-based documentation per the Medical Necessity Determinations administrative policy; individual genetic tests may be requested separately for panels that do not meet medical necessity.
- MCG criteria and Medical Necessity Determinations policy guide reviews
- Proprietary panels need evidence-based justification
Genetic Counseling Requirement
Genetic counseling is required for all germline genetic testing and must be provided by a healthcare professional with relevant education and training in genetic issues relevant to the tests under consideration. Counseling must enable informed decision-making by the member (purpose of testing, potential management implications, heritable nature with a 3‑generation family history, range of possible results, and potential benefits/risks such as psychological, social, and economic). Somatic genetic testing does not require the genetic counseling described above.
- Required for all germline genetic testing
- May be provided by appropriately trained healthcare professionals
- Somatic testing exempt from this counseling requirement
Provider Actions — Not Otherwise Specified
Providers: The document does not specify additional provider action details beyond prior authorization and documentation requirements. Verify prior authorization and include evidence-based documentation and genetic counseling (for germline tests) where applicable to avoid denial.
- Provider-specific actions beyond prior authorization are not specified in this policy
- Obtain prior authorization when required and supply documentation to support medical necessity
- Ensure genetic counseling is documented for germline testing
Proprietary Panel Testing
Proprietary panels: Evidence-based documentation per the Medical Necessity Determinations policy is required. If a panel does not meet medical necessity criteria, CareSource may request individual test justification or deny coverage.
- Proprietary panel testing requires evidence-based support
- Individual tests may be requested separately if panel fails medical necessity
Scope and Repeat Testing
HLA typing is outside the scope of this genetic testing policy and does not require prior authorization under this policy. Most inherited germline testing is typically performed once in a lifetime; repeat germline testing may be considered only in extraordinary circumstances with appropriate medical necessity documentation.
- HLA typing not covered by this policy — no preauthorization required
- Repeat germline testing allowed only with documented extraordinary justification
Definitions
Background and Rationale
Advances in genetic technology have expanded the identification of genetic variants. Genetic testing can provide diagnostic information or actionable therapeutic guidance, and results may affect clinical management. Because of these implications, CareSource requires medical necessity review (using published MCG criteria when available) for somatic and germline testing and emphasizes appropriate genetic counseling where specified.
Eligibility and Counseling Requirements
Genetic counseling for germline testing must include collection and interpretation of a three-generation family history to inform whether a condition is heritable and to support individualized risk assessment, in addition to explaining the purpose of testing, possible results, and benefits/risks to enable informed decision making.
Eligibility specifics for prior testing, ordering pathways, or additional documentation requirements are not specified in this policy.
Tests Not Covered
Proprietary panels that fail to meet medical necessity requirements per the Medical Necessity Determinations administrative policy are not covered; coverage may be provided for individual tests from the panel only if those tests independently meet medical necessity criteria and are supported by appropriate documentation.
OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
