CPT code 90736 denotes subcutaneous administration of a live vaccine to protect against varicella zoster infection. This code documents the clinical act of delivering a varicella vaccine and is central to immunization delivery, public health prevention efforts, and routine outpatient care. Accurate use of this code ensures that providers record vaccine administration separate from vaccine product reporting and supports surveillance and reimbursement processes nationwide.

Key payers in national analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Coverage and payment policies for vaccine administration can affect provider billing workflows, patient access to immunization services, and public health vaccine uptake.

Readers will find clinical context for the service, an overview of typical sites of service and operational considerations, and a concise look at payer coverage landscape. Content addresses benchmarking and policy-relevant issues at a national level where available. Data not available in the input will be noted where applicable.
