What 43220 covers

A gastroenterologist or other endoscopist passes a flexible scope through the mouth to examine the esophagus and dilate a narrowing with a balloon smaller than 30 mm. Typical situations include treatment of a benign esophageal stricture or ring in an outpatient endoscopy unit or hospital. The procedure is limited to esophagoscopy; a service that examines the stomach or duodenum may fall under an EGD code instead.

Report the code when the documentation supports transoral flexible esophagoscopy and balloon dilation, including the treated site and balloon diameter. It has a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, CMS applies endoscopy-family pricing. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.

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.

43220 billing questions

How does this differ from 43214?

Both describe transoral flexible esophagoscopy with balloon dilation. Use 43220 for a balloon under 30 mm; 43214 is for a balloon 30 mm or larger.

When would 43226 be a better fit?

43226 describes esophageal dilation over a guide wire. Choose based on the documented dilation technique, not simply because the same narrowing was treated.

Should an EGD dilation code be used instead?

Use an EGD code when the documented service is an upper endoscopy that includes examination beyond the esophagus. For EGD balloon dilation under 30 mm, compare 43249; for a balloon 30 mm or larger, compare 43233.

What should the procedure note include?

Document the transoral flexible esophagoscopy, the narrowing and its location, the balloon dilation performed, and the balloon diameter.

Can modifier 50 or an assistant-at-surgery claim be reported?

Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery for the service; co-surgeons and team surgery are not permitted.

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.
