What 45388 covers
A gastroenterologist or colorectal surgeon uses a flexible colonoscope to destroy lesion tissue rather than remove it as a specimen. Ablation may use methods such as argon plasma coagulation or electrocautery. A typical situation is treating residual adenomatous tissue at a prior polypectomy site; the code also covers ablation of other appropriate colonic lesions. The service is performed in settings where colonoscopy is provided, including hospital outpatient departments and ambulatory surgery centers.
Report the code when lesion destruction is performed, and document the lesion treated and the ablation method. When related endoscopies are performed together, CMS applies endoscopy-family pricing. The 0-day global period includes same-day preoperative and postoperative care. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, 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.

45388 billing questions
How is ablation different from lesion removal?
Ablation destroys lesion tissue; removal techniques such as forceps or snare excision take tissue out. Choose the code that matches the technique documented.
Can diagnostic colonoscopy be reported separately?
Do not separately report a diagnostic colonoscopy for the same examination when lesion ablation is performed. The diagnostic inspection is part of the therapeutic colonoscopy.
Should modifier 50 be appended for treatment on both sides of the colon?
No. CMS identifies bilateral adjustment as inapplicable to this code, so modifier 50 is inappropriate.
What does the 0-day global period include?
Same-day preoperative and postoperative care is included. Care on a later date is outside this 0-day global period.
How are related endoscopies priced when performed together?
CMS applies endoscopy-family pricing when related endoscopies are performed in the same session.
Can an assistant surgeon or co-surgeon be reported?
Medicare does not pay an assistant at surgery 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.
