CPT® Code 86706 is used to report hepatitis B surface antibody (HBsAb) testing, which detects antibodies against the hepatitis B surface antigen. The test is commonly used to determine whether a patient has developed immunity to hepatitis B, either from previous vaccination or from a past hepatitis B infection.
HBsAb testing can be useful when assessing immunity after vaccination, evaluating a patient's hepatitis B status, or determining whether additional vaccination or follow-up testing may be appropriate based on the clinical context.
This code represents the laboratory antibody test, not specimen collection or separate evaluation and management services.
Key Facts About CPT® 86706
- Service type: Laboratory immunology test
- Test: Hepatitis B surface antibody (HBsAb)
- Specimen type: Typically serum or plasma
- Test purpose: Assess immunity to hepatitis B
- Provider type: Physicians, laboratories, and qualified healthcare professionals
Common clinical indications:
- Assessment of hepatitis B vaccine immunity
- Post-vaccination antibody testing when clinically indicated
- Evaluation of hepatitis B immune status
- Healthcare worker or occupational exposure assessment
- Hepatitis B serologic evaluation
When to Use CPT® 86706
CPT 86706 is appropriate when:
- A provider orders hepatitis B surface antibody testing
- Determining whether a patient has developed hepatitis B immunity
- Evaluating immune status following vaccination
- Assessing hepatitis B serology as part of an infectious disease workup
- Testing is clinically indicated following potential exposure
Examples:
- Checking hepatitis B immunity in a healthcare worker when indicated
- Evaluating antibody response following a hepatitis B vaccination series
- Assessing hepatitis B immune status as part of a broader hepatitis panel
- Evaluating serologic status following a potential exposure
Documentation Requirements
To support CPT 86706 billing, documentation should include:
- Patient identifiers and date of service
- Clinical indication for hepatitis B antibody testing
- Relevant vaccination, exposure, or medical history when applicable
- Specimen information
- HBsAb test performed
- Test result and date reported
- Ordering provider information
Complete documentation supports medical necessity and accurate laboratory billing.
Reimbursement and Coding Considerations
- CPT 86706 reports hepatitis B surface antibody testing
- HBsAb testing should be distinguished from hepatitis B surface antigen (HBsAg) and other hepatitis B serologic tests
- Diagnosis coding should support screening, immunity assessment, exposure evaluation, or another medically necessary indication
- Coverage and testing requirements vary based on payer policies and clinical circumstances
- Specimen collection may be separately reportable when permitted by payer guidelines
Always verify payer-specific hepatitis B testing and preventive screening requirements before submitting claims.
