The Data

What the disclosures actually reveal.

A standing snapshot of the DFW market, built from the five major commercial insurers' public in-network files. These are market statistics only — no practice-specific data appears here.

The insurer spread

Median disclosed professional rate for the highest-volume GI procedures, by insurer. The distance between the columns is money left on the table for a practice anchored to the wrong insurer.

Median of unique tax-ID × rate observations per code and insurer, restricted to gastroenterology-taxonomy NPIs practicing in DFW counties. Procedure rates are the facility-setting professional fee (ASC / hospital outpatient); the office visit is POS 11. Medicare is the final CY2026 Physician Fee Schedule, Dallas locality, matched to setting. Figures rounded; individual practice rates vary widely around each median — see below.

The within-insurer range is just as wide.

The insurer spread is only half the story. On a single insurer, the gap between a practice at the 10th percentile and one at the 90th routinely approaches for the same code. Two GI groups a few miles apart, same insurer, can be paid dramatically differently for an identical colonoscopy.

This is the number a practice can move. A group sitting near an insurer's floor, holding documented evidence of the disclosed median, has a concrete, data-backed case for parity at renewal.

A practice at the low end earns roughly 53% less than one at the high end for the same procedure, with the same insurer, in the same city.

Where the numbers come from

Three independent public sources, each doing a specific job. Nothing here touches claims data or any patient-level information.

SOURCE 01

Insurer in-network files

The Transparency-in-Coverage disclosures — negotiated professional rates by tax ID and NPI, per code. The primary source, published monthly by each insurer.

SOURCE 02

Hospital price transparency

2026 hospital files add what insurers actually paid, drawn from remittance data, with claim counts — a cross-check on the negotiated rates and their real volume.

SOURCE 03

Medicare fee schedule

The CY2026 Physician Fee Schedule at the Dallas locality — the neutral yardstick every insurer contract is quoted against.
