The average billed charge in California is $169.44, 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 Medical Supplies procedures, the estimated commercial insurance price in California lands near $81.54, with self-pay cash prices typically around $72.08.
