What 94640 covers

This service covers an intermittent inhalation treatment delivered through a nebulizer, aerosol generator, metered-dose inhaler, or similar device to relieve acute airway obstruction or induce sputum for diagnostic testing. A common situation is nebulized bronchodilator treatment for a patient with acute wheezing or an asthma or COPD exacerbation. Physicians, nurses, and respiratory therapists may be involved in delivering the treatment in an office, clinic, or hospital setting.

Report one unit for an episode of care, even when the patient receives multiple inhalation treatments during that episode. For separate episodes on the same date, follow CPT reporting guidance for distinct episodes. Document the clinical reason, device or method, treatment provided, and the patient’s response. When billed as an incident-to service, CMS requires performance under physician supervision.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

94640 billing questions

Is 94640 reported for every nebulizer treatment?

No. Report one unit for the episode of care, regardless of the number of inhalation treatments provided during that episode. Distinct episodes on the same date are subject to CPT reporting guidance.

When is 94640 preferable to continuous inhalation treatment?

Use 94640 for an intermittent treatment for acute airway obstruction or diagnostic sputum induction. Code 94644 describes continuous inhalation treatment, with 94645 for each additional hour.

Can a nurse or respiratory therapist provide the service?

They may be involved in delivering it. When the service is billed as incident-to, it must be performed under physician supervision.

What documentation supports 94640?

Document the acute obstruction or diagnostic sputum-induction purpose, the treatment and delivery method, and the patient’s response. The record should support the reported episode of care.

Is inhaler instruction part of 94640?

No. 94640 represents treatment delivery, while 94664 is for demonstrating or evaluating the patient’s use of an inhalation device. Report the latter only when that distinct teaching or evaluation service is performed and supported.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
