CPT® Code 3210F

CPT® Code 3210F is a Category II CPT code used to indicate that a Group A Streptococcus (GAS) test was performed. Category II codes are generally used for performance measurement and quality reporting rather than for reimbursement of a clinical service.

Group A Streptococcus testing is commonly performed when evaluating patients with symptoms of possible streptococcal pharyngitis. Documenting that the appropriate test was performed can support quality measurement and tracking of clinical care.

Key Facts About CPT® 3210F

  • Service type: Category II performance measurement code
  • Clinical measure: Group A Streptococcus test performed
  • Purpose: Report that appropriate GAS testing was performed
  • Common setting: Evaluation of suspected streptococcal pharyngitis
  • Code category: Category II CPT code

Common clinical circumstances:

  • Sore throat evaluation
  • Suspected streptococcal pharyngitis
  • Fever with pharyngeal symptoms
  • Tonsillar inflammation or exudate
  • Evaluation of patients meeting clinical criteria for GAS testing

When to Use CPT® 3210F

CPT 3210F may be reported when the documented clinical encounter meets the applicable performance-measure criteria and a Group A Streptococcus test was performed.

Examples:

  • Performing a rapid Group A Streptococcus antigen test during evaluation of a sore throat
  • Performing GAS testing as part of an appropriate clinical assessment for suspected streptococcal pharyngitis
  • Documenting completion of GAS testing for quality measurement purposes

The actual laboratory test should be reported using the appropriate laboratory CPT code when applicable. For example, CPT 87430 may be used for Group A Streptococcus antigen detection by immunoassay when the service meets the code requirements.

Documentation Requirements

Documentation should clearly establish that Group A Streptococcus testing was performed and may include:

  • Patient identifiers and date of service
  • Relevant symptoms and clinical findings
  • Clinical indication for GAS testing
  • Type of strep test performed
  • Test date
  • Test result, when available
  • Assessment and diagnosis
  • Treatment or follow-up plan based on clinical findings and results

Accurate documentation supports both patient care and applicable quality reporting requirements.

Reimbursement and Coding Considerations

  • CPT 3210F is a Category II code used primarily for performance measurement and quality reporting
  • Category II codes are generally not used as substitutes for the CPT code describing the actual laboratory service
  • The applicable laboratory CPT code should be reported separately when appropriate
  • Documentation should support the quality measure represented by the code
  • Payer and reporting requirements may vary depending on the applicable quality program

Always verify current quality-measure specifications and coding requirements before reporting Category II codes.
