What it costs in a hospital or surgery center
In a doctor’s office, the office rate above is the whole Medicare payment. When the same procedure is done in a hospital or surgery center, the facility bills its own fee on top of the physician, which is what these totals show. They are 2026 national Medicare amounts.
Medicare may pay the facility separately for this code or package it into another service on the same day, so treat the facility share as an upper bound. Medicare allowed amounts are not what an uninsured patient is charged, and not a quote. Private plans typically allow more.

What these numbers are
Every figure on this page is a 2026 Medicare allowed amount: the physician line comes from the Physician Fee Schedule adjusted by geographic practice-cost indices, and the facility totals come from the CMS hospital outpatient (OPPS) and ambulatory surgery center rates. None of them is a hospital chargemaster price, your insurer's contracted rate, or a quote. Anesthesia, pathology, imaging reads and follow-up care are billed under their own codes when they apply, and an inpatient stay is paid a different way again. In Illinois the office and hospital physician lines for this CPT differ by $34.85.

Psychiatric Evaluation and how Illinois is priced
Illinois uses one of the more detailed locality maps in the Midwest: Chicago has its own locality, the suburban collar counties are priced separately, the East St. Louis area carries its own locality tied to the St. Louis market, and the rest of the state shares a fourth. Approved amounts step down noticeably from the city and suburbs to downstate, so the same procedure prices differently in Chicago, Naperville, Belleville, and Springfield. This four-way split makes Illinois one of the states where a ZIP-level check genuinely changes the answer. Downstate rates align more closely with neighboring rural states than with Chicagoland.
Chicago is one of the country's great medical hubs, with multiple academic medical centers and deep specialist supply, and its suburbs support large competing systems of their own. Downstate Illinois is a different market: smaller cities like Peoria, Springfield, and Champaign serve wide rural areas, and the Metro East suburbs orient toward St. Louis providers. Where you sit on that map shapes both price and choice.
This procedure: A psychiatric diagnostic evaluation is the comprehensive first appointment with a mental health professional, typically a psychologist, therapist, or psychiatrist, covering your history, symptoms, and goals to establish a diagnosis and treatment plan. It usually runs 60 to 90 minutes, longer than ordinary therapy sessions, and happens in an office or by telehealth. This version of the evaluation does not include medical services like prescribing, which distinguishes it from its sister code 90792.

What Affects the Cost
- –Many therapists and some psychiatrists do not accept insurance at all, making this a cash purchase at whatever the clinician charges.
- –Clinician credentials drive price: psychiatrists charge more than psychologists, who charge more than masters-level therapists, for the same code.
- –In-network negotiated rates are often far below the clinician's list price, so network status changes the cost more than almost anything else.
- –Telehealth platforms sometimes price intake evaluations differently from their ongoing session rates.
- –Out-of-network plans may reimburse a percentage of an allowed amount well below what the clinician actually charged, leaving you the gap.
Questions to Ask Before Booking
- 1.Are you in network with my plan, and if not, what is your rate for this evaluation?
- 2.Will ongoing sessions be billed at a different rate than this intake?
- 3.If I need medication, will you refer me for a separate 90792 evaluation with a prescriber, at what cost?
- 4.Does my plan offer a network-gap exception if no in-network therapist is available soon?
- 5.Do you provide superbills I can submit for out-of-network reimbursement?
