CPT (Current Procedural Terminology) codes are five-digit numeric codes used to describe medical, surgical, and diagnostic services. They are maintained by the American Medical Association and used by healthcare providers, insurers, and Medicare for billing and reimbursement.

What is the difference between facility and non-facility rates?

Non-facility (office) rates are what Medicare pays when a service is performed in a physician's office. Facility rates are lower because when a service is performed in a hospital or ambulatory surgery center, the facility bills separately for overhead costs like equipment and supplies.

RVU stands for Relative Value Unit. Medicare uses RVUs to measure the value of physician services based on three components: physician work, practice expense, and malpractice cost. Total RVUs are multiplied by the conversion factor ($33.40 in 2026) to calculate the Medicare payment amount.

Is F33.2 a billable ICD-10-CM code?

Yes. F33.2 (Major depressive disorder, recurrent severe without psychotic features) is a billable/specific ICD-10-CM code and can be reported on a claim when the documentation supports it.

What HCC does F33.2 map to?

F33.2 maps to HCC155 (Major Depression, Moderate or Severe, without Psychosis); HCC155 (Major Depression, Moderate or Severe, without Psychosis) in the CMS-HCC V28 risk-adjustment model (Medicare Advantage / Part C) for payment year 2026. An age edit applies (age < 2). Risk-adjustable diagnoses must be documented and resubmitted each year — and survive the CMS-HCC hierarchy and edits — to count toward a member's risk score.

In CMS's Hierarchical Condition Category (HCC) model — the risk-adjustment model for Medicare Advantage (Part C) — a documented and submitted F33.2 may contribute to a member's risk score (subject to the CMS-HCC hierarchy and edits), which helps drive the plan's capitated payment for that patient. To count, the diagnosis must be supported to the MEAT standard (Monitored, Evaluated, Assessed, Treated) and reported on an eligible face-to-face encounter at least once each calendar year — risk scores reset annually.

Documentation & coding notes

F33.2 is a billable/specific ICD-10-CM code — it can be reported as a primary or secondary diagnosis when the documentation supports it. Code to the highest level of specificity the record allows.
F33.2 is risk-adjustable: it maps to HCC155, HCC155 in the CMS-HCC V28 model (payment year 2026), the risk-adjustment model for Medicare Advantage (Part C). For the diagnosis to contribute to a member's risk score it must survive the CMS-HCC hierarchy and edits, be documented to the MEAT standard (Monitored, Evaluated, Assessed, Treated), and be submitted on an eligible face-to-face encounter at least once per calendar year.
Always verify the code against the current ICD-10-CM Official Guidelines and the payer's coverage policy before submitting — coverage, medical necessity edits, and sequencing rules vary by payer.
