CPT® Code 95921 is used to report autonomic function testing of cardiovagal innervation, specifically assessment of parasympathetic function. The service evaluates cardiovascular responses controlled by the autonomic nervous system.
This testing may be performed as part of an autonomic nervous system evaluation when a clinician needs to assess cardiovagal function.
Key Facts About CPT® 95921
- Service type: Autonomic nervous system testing
- Test: Cardiovagal function testing
- System assessed: Parasympathetic/autonomic cardiovascular function
- Purpose: Evaluate cardiovagal autonomic function
- Common specialties: Neurology, cardiology, autonomic medicine
- Provider type: Physician or qualified healthcare professional
Common clinical uses:
- Evaluation of suspected autonomic dysfunction
- Assessment of parasympathetic cardiovascular function
- Evaluation of autonomic neuropathy
- Assessment of abnormal cardiovascular autonomic responses
When to Use CPT® 95921
CPT 95921 may be reported when appropriate autonomic function testing is performed to evaluate cardiovagal innervation and parasympathetic function.
Examples:
- A patient is evaluated for symptoms suggesting autonomic dysfunction
- Cardiovascular autonomic testing is performed to assess parasympathetic responses
- Testing is used as part of an evaluation for suspected autonomic neuropathy
The specific testing performed should meet applicable CPT and payer requirements.
Documentation Requirements
Documentation supporting CPT 95921 should include:
- Patient identifiers and date of service
- Relevant symptoms, diagnoses, or clinical indications
- Reason autonomic testing was medically necessary
- Testing performed to evaluate cardiovagal function
- Test findings and measurements
- Interpretation of results, when applicable
- Provider authentication
The record should clearly connect the testing to the patient's clinical evaluation and document the autonomic function assessed.
Reimbursement and Coding Considerations
- CPT 95921 reports testing of cardiovagal innervation
- It is generally reported as part of autonomic nervous system testing when applicable
- Other autonomic testing codes may apply depending on the components performed
- Medical necessity and coverage requirements vary by payer
- Practices should verify current CPT and payer-specific coding requirements before submitting claims
Accurate documentation of the autonomic testing performed and the clinical indication helps support appropriate coding and reimbursement.
