Providers must follow specific billing and coding rules when submitting claims for vaccines and preventive services. Ensure correct HCPCS/CPT and diagnosis code pairing, place of service, and documentation to support medical necessity or preventive benefit. Failure to follow these rules may result in claim denials or recoupments.

Verify appropriate HCPCS/CPT code and matching ICD-10 diagnosis code on each claim
Use correct place-of-service and modifier codes when required
Document indication (preventive vs. medically necessary) in the medical record and on the claim when applicable
Follow payer-specific crosswalks and billing requirement references listed in internal billing guidance
