Specialty · Gastroenterology

Procedure-heavy. ASC fee schedules. Endless modifiers.

GI revenue lives in colonoscopy, EGD, and the ASC fee schedule layered underneath them. Modifier and bundling disputes are where commercial payers quietly underpay. Aroris benchmarks every code, payer by payer, and signs new rates.

Where GI revenue drifts

The four code families we see leaking most.

GI revenue concentrates in a handful of high-volume procedures layered on top of an ASC fee schedule. That layering is exactly where commercial payers quietly underpay. These are the code families we most often find drifting.

45378 / 45380

Colonoscopy, dx + biopsy

The backbone of GI volume. A few points below the contracted rate here outweighs almost any other single correction because of how often it is billed.

45385

Colonoscopy w/ polyp removal

Routinely subject to bundling and modifier logic that pays the diagnostic rate when the therapeutic rate was earned.

43239 / 43235

EGD, diagnostic + biopsy

High-frequency endoscopy codes where biopsy add-ons are a common silent downcode against the contracted schedule.

91110 / 91112

Capsule endoscopy

Lower volume but high per-unit value, and one of the codes most exposed when a payer fee schedule lags the national benchmark.

99213 / 99214

Office E/M

The same compounding E/M drift seen across every specialty, amplified in GI by high pre- and post-procedure visit volume.

-PT, -33, -59

Modifier handling

Screening-vs-diagnostic colonoscopy is the single most disputed modifier scenario in GI. Aroris tracks the -PT and -33 denial pattern by payer and builds it into the rate case.

How Aroris works with GI groups

ASC + professional, every modifier accounted for.

1. GI-specific benchmark

Your codes priced against the GI-only subset of the Aroris dataset, including ASC vs. office vs. hospital outpatient differentials.

2. Modifier-aware rate cases

Screening-to-diagnostic conversions and the -PT/-33 modifier disputes get specific case treatment.

3. Live monitoring after

Once new rates are signed, every claim is reconciled daily — modifier downcoding flagged the day it shows up.

Proof in GI

What we’ve signed for GI groups.

GI groups carry more revenue per procedure than almost any office-based specialty, and more modifier exposure. Here is the shape of a typical Aroris engagement.

Illustrative figures for layout review. Final signed-result numbers pending client approval.

+7–13%

Typical blended commercial lift across the colonoscopy and EGD families after corrected rates are signed.

2–4 mo

Benchmark to signed rate amendment for a mid-size GI group with an ASC.
