Pulmonology
94010 — Spirometry, including graphic record, total and timed vital capacity, expiratory flow rate measurement
Spirometry is a breathing test where you blow forcefully into a mouthpiece to measure how much air your lungs can hold and how quickly you can exhale.
- Typical setting: Doctor's office, hospital outpatient
- National avg charge (illustrative): $40–$200 (varies by facility and region)
- Most-disputed reason: Billing 94010 separately when 94060 (spirometry with bronchodilator before and after) was the actual service performed — 94010 is bundled into 94060 and should not appear as an additional charge.

Common errors with this code
What goes wrong on real bills.
Most bills that look correct still contain at least one of these issues. Up to 49% of medical bills contain errors (CFPB).
- Billing 94010 separately when 94060 (spirometry with bronchodilator before and after) was the actual service performed — 94010 is bundled into 94060 and should not appear as an additional charge.
- Spirometry billed during a routine office visit without documentation that it was a separately performed, medically necessary diagnostic test.
- Missing interpretation documentation — codes 94010–94799 require that laboratory procedures and interpretation be included; a standalone tracing without a physician interpretation does not support separate billing.
