What 43252 covers

During an upper gastrointestinal endoscopy, the endoscopist uses optical endomicroscopy to examine selected mucosal areas at microscopic resolution while viewing the tissue in real time. The technique can help characterize suspicious mucosal changes, including areas evaluated during Barrett esophagus surveillance. Gastroenterologists typically perform it in a hospital or ambulatory endoscopy setting as part of an EGD; it is not a tissue specimen examination by pathology.

Report this code when optical endomicroscopy is performed during the EGD, and document the areas examined and the imaging service. When related endoscopies are performed together, CMS applies endoscopy-family pricing rather than pricing each as an unrelated standalone procedure. The 0-day global period includes same-day preoperative and postoperative care. CMS does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted. Modifier 50 is inappropriate for this code.

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.

43252 billing questions

How is this different from EGD with biopsy, 43239?

This code describes real-time optical microscopic imaging of mucosa. Code 43239 describes obtaining tissue for histologic examination; imaging alone is not a biopsy.

Can biopsy or lesion treatment also be reported at the same session?

A separately performed biopsy or therapeutic service may have its own code, but document the distinct service and apply applicable coding and endoscopy-family pricing rules.

Should modifier 50 be appended?

No. CMS identifies bilateral adjustment as inapplicable and modifier 50 as inappropriate for this service.

Is an assistant surgeon payable?

CMS lists a statutory restriction on assistant-at-surgery payment for this code. Co-surgeons and team surgery are not permitted.

What same-day care is included in the global period?

The 0-day global period includes same-day preoperative and postoperative care.

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.
