Coverage and Medical Necessity Criteria
Medical Necessity determination
Covered when ALL of the following are met
Generally accepted standards are based on peer-reviewed literature, specialty society recommendations, and views of practicing physicians.
BCBSNC does not cover investigational, cosmetic, or other services that do not meet the insurer's definition of Medical Necessity. Member benefits should be confirmed via the Member's Benefit Booklet because benefit availability may vary by plan.
Services that do not meet the policy's Medical Necessity definition will not be covered or reimbursed by BCBSNC. The fact that a provider prescribes or recommends a service alone does not establish Medical Necessity.

Provider Responsibilities and Impact
Verify member benefits and eligibility before applying Medical Necessity
Benefits and reimbursement depend on the Member's benefit design and eligibility; confirm coverage under the Member's Benefit Booklet before applying Medical Necessity criteria.
- Review the Member's Benefit Booklet for availability of benefits.
- Confirm member eligibility and benefit design prior to submitting claims or determinations.
Operational note: apply policy terms consistent with member benefit language
Follow any operational or administrative notes in the policy and the member's benefit documents when submitting services for review.
- Apply the policy terms only to services described in the medical policy and consistent with the member's benefit language.
Provide full medical records on request; letters alone are insufficient
BCBSNC may request medical records to determine Medical Necessity; letters of support or explanation can be helpful but are not sufficient unless they contain all specific information needed for the determination.
- Provide complete medical records when requested.
- Do not rely solely on letters of support — include the clinical details required to establish Medical Necessity.
Denial risk: services not meeting Medical Necessity will not be covered
If BCBSNC determines a service does not meet the policy definition of Medical Necessity, the service will not be covered or reimbursed.
- Coverage requires that all Medical Necessity criteria in the policy are met.
- Services that are investigational, cosmetic, or otherwise not meeting Medical Necessity are excluded from coverage.
Policy Background
This policy defines BCBSNC's operational definition of Medical Necessity and is used to adjudicate coverage for diagnostic services, procedures, tests, treatments, facilities, equipment, drugs, and devices. Determinations require that all specified criteria are met (see Coverage Criteria) and are applied consistently across product lines; benefit language in the Member's Benefit Booklet must be reviewed prior to applying the Medical Necessity criteria.
Key Definitions
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.
