Billing/Precertification criteria
Billing and administrative criteria
Codes and Code Groups
| The document references a separate published list of medical procedure codes for services that require precertification (available on the Medical Policy Portal for Medicare Advantage members). |
Provider Precertification Responsibilities
Prior Authorization Required
Precertification applies to elective, non-emergency services. Because a service or item is subject to precertification, it does not guarantee coverage — the member's benefit plan terms and exclusions must be reviewed to determine actual coverage.
- Applies to services performed on an elective, non-emergency basis.
- Precertification does not assure payment or coverage; confirm benefits and exclusions in the member's plan.
Carelon Precertification Review
Carelon performs precertification reviews for certain services listed by AmeriHealth. Providers should submit precertification requests to Carelon for the applicable services and confirm whether the member's employer group decision affects review benefits.
- Carelon is an independent company handling precertification for listed services.
- Precertification review benefit may vary based on the member's employer group decision.
ABA Precertification by Magellan
Precertification review for Applied Behavioral Analysis (ABA) for autism spectrum disorders is handled by Magellan Healthcare, Inc., an independent company. Providers should direct ABA precertification requests to Magellan as indicated.
- Applies to Applied Behavioral Analysis for autism spectrum disorders.
- Magellan Healthcare, Inc. conducts the precertification review for ABA services.
Precertification for Nonspecific / Unlisted Genetic Tests
Any genetic test billed with a non-specific or unlisted procedure code requires precertification. Examples include broad genetic CPT ranges and common unlisted genetic procedure codes.

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.
