Use modifier -78 for conversions after PEG tube placement

Why This Topic Matters

PEG and G-tube/GJ-tube cases can be coded differently depending on whether the service is an initial placement, a replacement, a conversion, or a follow-up study. Correct reporting affects claim payment, bundling, and modifier use during the global period.

Article Sections

1. Initial PEG tube placement and immediate conversion scenarios

   This section introduces first-time placement of gastric or gastrojejunostomy tubes and discusses how closely timed procedural steps are addressed in coding guidance. It also references the related radiology supervision and interpretation component.

2. Conversion during the postoperative global period

   This section focuses on a later conversion between tube types during the global period after an original placement. It addresses the circumstances that make postoperative modifier reporting relevant.

3. Tube adjustment, replacement, and exchange scenarios

   This section distinguishes between routine tube changes and situations involving adjustment, replacement, or exchange. It compares those scenarios with other PEG-related services discussed in the article.

4. Follow-up contrast assessment of tube position or patency

   This section covers imaging-based assessment of a previously placed tube using contrast and fluoroscopy. It also notes that some payers may prefer alternative reporting approaches for the same general service.
