0657T Medicaid reimbursement rate by state (2026)

• Order. States are listed from the highest published rate to the lowest. No single unit is shared by 8 or more states for 0657T, so the order is by published amount and is not a like-for-like rank.
• Medicaid rate. The most the state's fee-for-service program pays for one unit, as published. 3 of the 6 states list more than one rate for 0657T, by modifier, provider type or setting; the table shows the one that matches the provider level and setting used across states, without add-ons.
• Unit. None of the 6 schedules prints a separate unit for 0657T, so each amount is a flat payment for one service as the code defines it.
• Per hour. 0657T is not billed in time units in these states, so no hourly figure is shown.
• Managed-care plans. The rule the state sets for its plans on this rate. What each rule means is explained below.
• % of Medicare. No Medicare physician fee schedule amount is on file for 0657T, so there is no percentage.
• Source and date. Each Source link opens the state's own document; “since” is the date the rate took effect.

Published rates for 0657T run from $195.96 in South Dakota to $13,236.53 in Arkansas, a 67.5x gap in the same unit. Half the states pay more than the median of $3,726.89 and half pay less. The usual reasons for a spread like this in hospital outpatient rates:

• Many outpatient amounts are hospital-specific or adjusted by hospital type.
• States pay outpatient hospital care under different systems: grouped payments, a fee schedule or a percentage of charges.

Timing matters too. 6 states set the current rate for 0657T in 2026 or later. A state that has not updated its rate in years will drift down the ranking as others raise theirs.

What a plan pays for 0657T is negotiated privately, but the state decides how much room there is to negotiate. Here is how the rules break down across the 6 states.

In 1 state, the published rate binds plans: a floor, a pass-through or a state-set rate. In 2 states, plans negotiate and the published rate is a benchmark or out-of-network default. The rule for the remaining 3 states is not classified yet.

• Plans negotiate; the published rate applies out of network (2 states). In-network rates can be above or below the published rate. The published rate is the benchmark both sides know, and the fallback if no contract is signed.
• Plans must pay at least the published rate (1 state). The published rate is your floor. Negotiate up from it, and if a plan pays less, the contract provision is the basis for a payment dispute.

Plan-negotiated rates are never estimated here. To see the rule and its citation for a particular state, open that state's managed-care page, for example Arkansas managed care.

0657T is a CPT Category III code in the hospital outpatient line, billed mostly by hospital outpatient departments. Category III codes are temporary codes for emerging technology. Payers often price them case by case, so fewer states publish a fixed fee.

Outpatient services are billed per procedure, and some systems package lower-cost items into the payment for the main service.

Before billing, confirm the rate, unit and any modifier with the state's current schedule or the plan: the amounts here are as published, not a guarantee of payment.
