Gastrointestinal endoscopy
About 43252: EGD with optical endomicroscopy
Reports optical endomicroscopic imaging performed during upper endoscopy to assess gastrointestinal mucosa at microscopic resolution in real time.
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.

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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
