What 44363 covers

A gastroenterologist or other qualified endoscopist advances an enteroscope beyond the second portion of the duodenum to examine the small bowel and remove a lesion with a snare. The service is commonly performed in a hospital or ambulatory endoscopy setting when a small-bowel lesion has been identified or is encountered during enteroscopy. The report should identify the extent of examination, the lesion treated, and the snare technique used.

Choose this code for snare removal, not for diagnostic examination alone, tissue sampling, or removal by another method. Document the target and treatment performed; the record should support that the instrument reached the small bowel beyond the second duodenal portion. CMS applies endoscopy-family pricing when related endoscopies are performed together. The 0-day global period includes same-day preoperative and postoperative care. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

44363 billing questions

How does this differ from 44361?

44363 is for snare removal of a lesion. 44361 describes small-bowel endoscopy with biopsy, so use it when tissue is sampled rather than removed by snare.

When should 44364 be considered instead?

Use 44364 when the lesion is removed with hot biopsy forceps or bipolar cautery rather than a snare. The documented removal method distinguishes these codes.

Can diagnostic enteroscopy be reported separately with 44363?

The examination is part of the therapeutic enteroscopy. When related endoscopies are performed together, CMS endoscopy-family pricing applies.

Can modifier 50 be used?

No. CMS identifies bilateral adjustment as inappropriate for this code because of its descriptor or anatomy.

What does the 0-day global period include?

Same-day preoperative and postoperative care is included. The global period is limited to the procedure date.

What documentation supports assistant-at-surgery payment?

The record must document medical necessity for the assistant. CMS does not permit co-surgeons or team surgery for this service.

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.
