Coverage Determination
Not covered — investigational
Covered when ALL of the following are met:
BCBSNC does not provide coverage for investigational services or procedures.
There are no circumstances under which electronic brachytherapy for nonmelanoma skin cancer is listed as covered by BCBSNC; the policy section for covered indications is explicitly labeled Not applicable.
Because the policy provides no coverage scenarios for this procedure, providers should not expect approval or payment for electronic brachytherapy for NMSC based on this policy.
BCBSNC policy states that electronic brachytherapy for nonmelanoma skin cancer is investigational for all applications. As an investigational service, it is not eligible for coverage under this policy.
Claims for electronic brachytherapy to treat basal cell or squamous cell carcinoma of the skin are subject to denial on the basis that the treatment is investigational.
Billing and Coding
Provider Actions and Billing Notes
Electronic brachytherapy classified as investigational — no coverage
Providers must follow BCBSNC policy requirements for investigational services: electronic brachytherapy for nonmelanoma skin cancer is considered investigational and is not covered, so do not expect payment authorization for this indication.
Provide medical records on request; letters alone usually insufficient
BCBSNC may request medical records to determine medical necessity; letters of support or explanation are not sufficient unless they contain all specific information needed to make the medical necessity determination.
- When records are requested, include complete medical documentation rather than only letters of support.
- Be prepared to supply requested charts, notes, and imaging/treatment details to substantiate necessity.
Claims will be denied — investigational service
Claims for electronic brachytherapy for nonmelanoma skin cancer will be denied as investigational and are not eligible for coverage.
Background and Clinical Context
Nonmelanoma skin cancers, primarily basal cell carcinoma and squamous cell carcinoma, are common cutaneous malignancies most often managed with surgical excision. When surgery is not feasible or is undesirable for cosmetic or functional reasons, radiotherapy is an accepted alternative.
Electronic brachytherapy is a localized form of radiotherapy that uses a miniaturized electronic x‑ray source delivered via a surface applicator or mold to treat well‑circumscribed superficial skin tumors; it can shorten treatment schedules and avoids the use of radionuclides.
Despite these characteristics, BCBSNC has determined that the evidence is insufficient to support the routine use of electronic brachytherapy for NMSC, and thus considers the technique investigational for all indications.
