California Pricing in Context
In California, CPT code 84590 (Vitamin A Level) carries an average Medicare payment of $11.06 — 2% below the national benchmark of $11.32. 24 providers across the state submitted claims for this procedure in 2023, performing 4.2K total services. Individual payments in CA ranged from N/A at the low end to N/A at the high end, reflecting differences in provider setting (office vs. facility), modifiers, and the specific geographic locality code applied within the state.
The average billed charge in California is $134.78, which is the figure uninsured patients would most likely encounter before any negotiation or charity discount. Medicare, by statute, only reimburses the allowed amount — the balance between billed and paid is written off under provider participation agreements. Insured patients generally pay a negotiated rate that falls between these two figures; the exact amount depends on plan design, deductible status, and in-network participation. Because California sits below the national Medicare average, commercial rates in the state may also run lower than the US median.
Using RAND 2024 commercial-to-Medicare ratios for Laboratory procedures, the estimated commercial insurance price in California lands near $26.55, with self-pay cash prices typically around $45.36. Before scheduling, patients can request a Good Faith Estimate under the No Surprises Act, compare cash rates from hospital Machine-Readable Files, and confirm whether the provider is in-network with their specific plan.
