74420 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 74420, 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. 43 of the 49 states list more than one rate for 74420, 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. Of the 49 states, 2 publish 74420 per unit, and 47 schedules print no unit at all (a flat amount per service).
• Per hour. 74420 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. Medicare amounts exist for 74420, but no state's Medicaid unit matches Medicare's billing unit closely enough to compute a percentage.
• Source and date. Each Source link opens the state's own document; “since” is the date the rate took effect.

Published rates for 74420 run from $16.00 in Alabama to $89.30 in Wisconsin, a 5.6x gap in the same unit. Half the states pay more than the median of $47.87 and half pay less. The usual reasons for a spread like this in radiology rates:

• Advanced imaging such as CT, MRI and PET is often under separate pricing and prior-authorization policies that vary from state to state.
• Imaging fees are split into a professional component (the reading) and a technical component (the equipment and staff), and states publish one, the other or a global amount.
• Some states pay hospitals for the technical component through an outpatient system and pay only the professional component from the physician schedule.

Timing matters too. 31 states set the current rate for 74420 in 2026 or later, while 8 states still pay a rate that took effect in 2022 or earlier. A state that has not updated its rate in years will drift down the ranking as others raise theirs.

Most Medicaid members are in managed-care plans, and plans don't publish their provider fee schedules. For 74420, the public signal is the rule each state sets for its plans, recorded on each rate above.

In 8 states, the published rate binds plans: a floor, a pass-through or a state-set rate. In 26 states, plans negotiate and the published rate is a benchmark or out-of-network default. The rule for the remaining 15 states is not classified yet.

• Plans negotiate; the published rate applies out of network (26 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 (8 states). 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 Wisconsin managed care.

74420 is a CPT radiology code in the radiology line, billed mostly by radiology groups, imaging centers and hospitals. Imaging codes are paid per study and split into a professional component (the reading, modifier 26) and a technical component (the equipment and staff, modifier TC). A global amount covers both.

Imaging is billed per study, with modifier 26 for the professional component and TC for the technical component; a claim without either is paid at the global amount where the state publishes one. Contrast agents and radiopharmaceuticals are usually billed separately under their own codes.

Medicare's 2026 physician fee schedule pays $71.78–$110.48 for 74420 (non-facility), depending on the Medicare locality. That is a useful reference point, but Medicare and Medicaid can define the unit differently, so compare only where the units match.

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.
