What 43229 covers

A gastroenterologist or other qualified endoscopist advances a flexible scope through the mouth to visualize and ablate targeted esophageal tissue. A typical setting is endoscopic treatment of Barrett’s esophagus with dysplasia; the treatment destroys the target tissue rather than removing it with forceps or a snare. The service is distinct from diagnostic inspection, biopsy, and endoscopic removal of a lesion.

Report the code when the documented service includes esophageal lesion ablation, not merely examination or tissue sampling. The procedure note should identify the treated esophageal site and lesion, the ablation performed, and the clinical indication. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy-family pricing applies. Modifier 50 is inappropriate for this descriptor and anatomy. Medicare does not pay an assistant at surgery for this service; 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.

43229 billing questions

How is ablation distinguished from endoscopic lesion removal?

Use this code for ablation of the esophageal target. Codes 43216 and 43217 describe lesion removal by specific techniques, including forceps or cautery and snare removal.

Can this code be reported for diagnostic esophagoscopy alone?

No. The service must include treatment by ablation; inspection or biopsy without ablation does not support this code.

Is modifier 50 appropriate for ablation on both sides of the esophagus?

No. CMS identifies bilateral adjustment as inappropriate for this descriptor and anatomy.

How are related endoscopies priced when performed together?

CMS applies endoscopy-family pricing when related endoscopies are performed together, rather than pricing each related scope service independently.

Does Medicare pay an assistant or co-surgeon for this procedure?

An assistant at surgery is not paid for this 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.
