Billing Codes and Reimbursement

How genetic counseling gets paid for shapes where genetic counselors can work and whether a service line survives. The coding landscape has changed recently and remains uneven across payers and states, so the practical knowledge is which code applies, who may bill it, and what the alternatives are when direct billing is unavailable.

• CPT 96041 is the current code for genetic counseling by a genetic counselor, effective January 2025. It replaced the long-standing 96040 and removed the face-to-face-only restriction, so associated work such as chart preparation, test coordination, documentation, and care communication is now within the code's description rather than uncompensated.
• CPT 96040, the predecessor code, was billed per 30 minutes of face-to-face time and was deleted at the end of 2024. It appears throughout older material, which is why the transition is worth knowing rather than just the current code.
• S0265 is a temporary HCPCS code some payers use for genetic counseling, and 99401 to 99404 are preventive medicine counseling codes sometimes used where no better option exists.
• Incident-to billing allows services to be billed under a supervising physician's provider number when the counselor cannot bill independently. It carries specific supervision requirements, and the payment goes to the physician's number rather than establishing the counselor as a recognized provider.
• Medicare does not recognize genetic counselors as independent providers. This is the central structural problem in the field: a counselor cannot enroll and bill Medicare directly, which limits practice models and makes many services invisible in payment data. The Access to Genetic Counselor Services Act has been introduced repeatedly to change this.
• State licensure is the lever that most affects commercial billing. In licensed states, counselors are more likely to be credentialed by commercial payers and to bill under their own provider number. Licensure status varies by state and continues to expand.
• Facility versus professional billing determines who captures revenue. A hospital-employed counselor's work may be billed as a facility service, which can obscure the counselor's individual contribution in institutional accounting and complicate the case for expanding a service.
• Telehealth billing rules evolved substantially and remain payer-specific, including whether the patient's location and the provider's location affect eligibility.
• Value beyond the encounter code. Because direct reimbursement is constrained, the economic case for genetic counseling frequently rests on downstream effects: avoided inappropriate testing, correct test selection, reduced duplicate ordering, and improved authorization success. Counselors making a staffing case should be prepared to quantify these.

• A counselor in a licensed state is credentialed with the major commercial payers and bills 96041 under her own number. A colleague in a neighboring state without licensure performs identical work billed incident-to the supervising physician, and her productivity is invisible in the department's provider-level reporting.
• A Medicare patient is seen for hereditary cancer counseling. The visit cannot be billed to Medicare under the counselor's own number. The practice bills the physician's evaluation and management service for the physician's portion, and the counseling time is absorbed.
• A department proposes cutting a counselor position on the grounds that the position does not generate enough professional revenue. The counselor assembles data on tests redirected or cancelled after counseling and on prior authorization approvals obtained, and the avoided cost exceeds the salary. The position is retained.
• A practice continues submitting 96040 into 2025 and the claims reject. The fix is the code change rather than the documentation, and the rejections resolve once billing is updated to 96041.
