The average billed charge in Colorado is $61.15, 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 Colorado sits above the national Medicare average, commercial rates in the state may also run higher than the US median.
