Quick Explanation
Denial code ON30 indicates that a medical claim for genetic counseling services was rejected because the provider failed to obtain the required prior authorization from the patient's insurance payer before the session took place. Payers mandate this pre-service approval to verify medical necessity and ensure the counseling is performed by a qualified, credentialed genetics professional.
Common Causes for ON30
Denials with code ON30 typically happen for the following specific reasons:
- The provider failed to verify the payer's pre-authorization list for CPT code 96040 or S0265 prior to scheduling the patient's visit.
- A prior authorization was secured for the genetic test itself, but the separate professional genetic counseling session was omitted from the authorization request.
- The counseling session occurred outside of the active date range approved in the original authorization letter.
- The service was rendered by a genetic counselor whose taxonomy or credentialing did not match the specific provider listed on the approved authorization.
How to Prevent ON30 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Establish a mandatory insurance verification step to screen all genetic services for prior authorization requirements during the scheduling workflow.
- Develop standard templates for submitting clinical notes, family pedigrees, and medical history to accelerate the pre-authorization approval process.
- Confirm that the approved authorization letter matches the exact CPT codes, dates of service, and rendering provider credentials before the service is provided.
- Maintain a centralized, frequently updated insurance rules engine to flag genetic counseling codes that require pre-service clearance.

Denial Code: ON30 - Genetic counseling not pre-authorized
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code ON30: "Genetic counseling not pre-authorized".
We are writing to appeal the denial of genetic counseling services (billed under CPT code 96040) under denial code ON30. Although prior authorization was not obtained prospectively, the enclosed medical records demonstrate that the patient met all clinical criteria and medical necessity requirements for genetic risk assessment based on their personal and family history. According to AMA and ACMG guidelines, pre-test and post-test genetic counseling is a critical component of evidence-based genetic evaluation. Since the service was clinically indicated, medically necessary, and delivered by a qualified genetics professional, we respectfully request a retrospective authorization and approval of this claim for payment.
Attached please find:
1. A copy of the original claim.
2. The relevant medical records supporting the service.
3. [Any other supporting documents].
We respectfully request that you reprocess this claim for payment.
Sincerely,
[Your Name]
