A payer’s file carries a rate for every code in the contract’s fee class, whether or not the clinician will ever bill it. These rows are real, and they are how the fee class shows through — but they are not evidence that Michael Keller, MD performs these services, and they are kept out of the benchmark above.

Sources. Cigna — Houston FlexCare (September 2026). Each payer’s machine-readable file, joined to the national provider registry by NPI. Rates are the negotiated professional amounts — not billed charges, and not what a member owes after cost sharing. Where a file carries several contract rows for one clinician and code, the median is shown with the range and row count beneath it.

Medicare. Non-facility allowed amount, HOUSTON, Texas, Locality 18, CY2026 non-QP conversion factor, computed from RVUs and the locality’s geographic indices — not looked up from a table.

Position. Percentile of this rate among Houston clinicians in the same specialty holding a rate for the same code on the same plan; falls back to all Houston clinicians on that plan where the specialty cohort is under ten. Payers are never pooled.
