CPT 94640

Understanding Your Nebulizer Treatment Bill (CPT 94640)

CPT code 94640 is used when you receive a nebulizer treatment to help you breathe better. This code covers the actual breathing treatment, whether using a pressurized or non-pressurized nebulizer machine.

What Medicare Pays vs. What You Might Be Charged
Category Amount
Medicare Allowed Rate What Medicare approves for this service $15.73
Typical Billed Amount What providers commonly charge $30 – $200
Potential Markup How much more you might pay vs. Medicare rate 1171% above Medicare
Why the difference? Providers set their own prices. Without insurance, you may be billed the full amount. Even with insurance, your co-pay is often based on the provider's charge — not the Medicare rate.

What CPT 94640 Means and When It's Used

CPT code 94640 represents a nebulizer treatment, which is a common breathing therapy used to deliver medication directly to your lungs. During this treatment, you breathe in medication that's been turned into a fine mist through a nebulizer machine.

Your doctor might order this treatment if you have asthma, COPD, pneumonia, or other breathing problems. The treatment typically takes 10-15 minutes and can be done in a doctor's office, hospital, or emergency room. The code applies whether the nebulizer uses pressurized air or operates without pressure.

This is a pulmonary (lung-related) procedure that's very common and considered routine medical care. You might receive multiple treatments during a single visit, and each treatment would be billed separately using this code.

How Billing Works for Nebulizer Treatments

When you see CPT code 94640 on your medical bill, you can expect charges to range from $30 to $200 per treatment, depending on your healthcare provider and location. Medicare reimburses providers $15.73 for this service, which gives you an idea of the baseline cost.

The wide price range exists because different facilities have different overhead costs. Hospital emergency rooms typically charge more than outpatient clinics or doctor's offices. Your insurance coverage will also affect what you actually pay out of pocket.

If you receive multiple nebulizer treatments during one visit, you should see this code listed multiple times on your bill. Each treatment session gets billed separately, so receiving three treatments would result in three separate CPT 94640 charges.

How to Verify Your Nebulizer Treatment Charges

To check if your nebulizer treatment was billed correctly, first confirm that you actually received the treatment. Look for CPT code 94640 on your bill and count how many times it appears – this should match the number of nebulizer treatments you remember receiving.

If the charge per treatment exceeds $200, or if you see charges but don't remember receiving nebulizer treatments, contact your healthcare provider's billing department. Ask them to explain each charge and provide documentation of when the treatments were given.

You can also contact your insurance company to review the charges. They can tell you what's typical for your area and help you understand your coverage. If you find errors, both your provider and insurance company can help correct them, potentially saving you money on your medical bills.
