What 43206 covers

A gastroenterologist or other qualified endoscopist uses a flexible scope passed through the mouth to examine the esophagus and obtain microscopic images of its lining in real time. The added imaging can help characterize abnormal mucosa, including areas evaluated during assessment of Barrett’s esophagus. It provides an optical view of tissue architecture rather than a specimen for conventional histologic examination.

Choose this service when the procedure record documents optical endomicroscopy during flexible transoral esophagoscopy, including the examined area and imaging findings. A tissue biopsy or brush sampling is a different service; when related endoscopies are performed together, CMS endoscopy-family pricing applies. The 0-day global period includes same-day preoperative and postoperative care. Modifier 50 is inappropriate for this single esophageal service. Medicare does not pay an assistant at surgery, 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.

43206 billing questions

How does this differ from esophageal biopsy code 43202?

Code 43206 captures optical microscopic imaging of the esophageal lining; 43202 captures tissue sampling for histologic examination. Document the imaging and any biopsy separately when both are performed.

Is this an EGD that includes the stomach and duodenum?

No. This service is flexible transoral esophagoscopy with optical endomicroscopy. An EGD code describes examination extending beyond the esophagus.

Should modifier 50 be appended?

No. The esophageal service is not bilateral work, and modifier 50 is inappropriate.

What documentation supports reporting 43206?

Record the flexible transoral esophagoscopy, use of optical endomicroscopy, the esophageal area assessed, and the imaging findings.

How is it handled when another related endoscopy is performed in the same session?

CMS endoscopy-family pricing applies when related endoscopies are performed together. The record should identify each procedure actually performed.

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.
