94010

Spirometry

Code Description

CPT code 94010 is used to report spirometry testing that measures lung function, including vital capacity and expiratory airflow measurements. The service includes a graphic record and may include maximal voluntary ventilation when performed.

Spirometry is commonly used to evaluate respiratory symptoms and assess obstructive lung diseases such as asthma and chronic obstructive pulmonary disease (COPD). The test measures how much air a patient can move out of the lungs and how quickly the air is expelled.

When to Use 94010

Common examples include:

  • Shortness of breath

  • Chronic cough

  • Wheezing

  • Suspected asthma

  • Evaluation of COPD

  • Monitoring known lung disease

  • Medically necessary preoperative pulmonary evaluation

Documentation Requirements

Documentation should include:

  • Reason for the spirometry test

  • Relevant respiratory symptoms or diagnosis

  • Spirometry measurements obtained

  • Graphic test results

  • Provider interpretation

  • Written report of the findings

The medical record should support the clinical need for the test, particularly because routine or repetitive respiratory testing without medical necessity may not be considered reasonable.

Common Billing Mistakes

Common billing mistakes include:

  • Reporting the wrong pulmonary function test code

  • Confusing basic spirometry with pre- and post-bronchodilator testing

  • Failing to maintain the test results and interpretation

  • Repeating testing without documented medical necessity

  • Insufficient documentation of the reason for the test
