CPT code 94640

What does CPT code 94640 mean on a medical bill?

This is the charge for a breathing treatment: medicine turned into a mist you breathe through a mask or mouthpiece. Each treatment given is normally its own line, and the medicine itself is billed separately, so someone who got three treatments during a long asthma visit will see several lines. The count on your bill should match the number of treatments written in the nursing notes.

What does CPT code 94640 usually cost?

Billed per treatment by the hospital, with the drug on its own line. The same treatment is priced very differently in a doctor's office, an urgent care, and an emergency room, because each setting adds its own overhead to the charge.

What should I watch out for with CPT code 94640?

• More treatments billed than the nursing notes record
• A treatment and a continuous nebulizer line billed for the same stretch of time
• The inhaler you were sent home with billed as a treatment given in the department
