CPT® Code 84207 is used to report laboratory testing for pyridoxal phosphate, the active coenzyme form of vitamin B6. Measuring pyridoxal phosphate can help evaluate vitamin B6 status when deficiency or abnormal vitamin metabolism is suspected.
The test may be ordered as part of an evaluation of nutritional status, neurologic symptoms, or other conditions associated with vitamin B6 abnormalities.

The test should be ordered based on the patient's clinical circumstances and documented medical necessity.
Documentation Requirements
Documentation supporting CPT 84207 should include:
- Patient identifiers and date of service
- Clinical indication for testing
- Relevant symptoms, diagnoses, or nutritional concerns
- Pyridoxal phosphate test ordered or performed
- Laboratory results
- Clinical interpretation when applicable
- Provider authentication
The record should establish why pyridoxal phosphate testing was medically appropriate.
Reimbursement and Coding Considerations
- CPT 84207 represents testing for pyridoxal phosphate
- Medical necessity and coverage requirements vary by payer
- The laboratory's specimen and testing requirements should be followed
- Additional vitamin or nutritional testing should be reported separately when appropriate and supported
- Practices should verify current payer-specific policies before submitting claims
Accurate documentation of the clinical indication and laboratory findings helps support appropriate coding and reimbursement.
