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.

Sources. Aetna — Texas (office visit and psychotherapy codes only) (August 2026 extract). 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.
