99602 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 99602, 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. Each state lists a single rate for 99602.
• Unit. Of the 9 states, 1 publish 99602 per percent of billed charges, and 8 schedules print no unit at all (a flat amount per service).
• Per hour. 99602 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 99602, 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 99602 run from $30.97 in Oregon to $102.00 in Alaska, a 3.3x gap in the same unit. Half the states pay more than the median of $41.85 and half pay less. The usual reasons for a spread like this in physician & professional rates:

• Each state sets its own physician conversion factor or fee for every code, and many update them on a state budget cycle rather than on Medicare's calendar.
• Modifiers such as professional or technical component, bilateral, multiple procedure and assistant at surgery change the amount paid, and states apply them with their own percentages.
• Many schedules pay differently by place of service (office versus facility) and by practitioner, and nurse practitioners and physician assistants are often paid a percentage of the physician amount.

Timing matters too. 2 states set the current rate for 99602 in 2026 or later, while 4 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.

What a plan pays for 99602 is negotiated privately, but the state decides how much room there is to negotiate. Here is how the rules break down across the 9 states.

In 3 states, the published rate binds plans: a floor, a pass-through or a state-set rate. In 4 states, plans negotiate and the published rate is a benchmark or out-of-network default. The rule for the remaining 2 states is not classified yet.

• Plans negotiate; the published rate applies out of network (4 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 (2 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.
• The state sets the plan rate (1 state). There is little to negotiate on price. Contracting is about network participation, authorization and billing terms.

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 Alaska managed care.

99602 is a CPT medicine code in the physician & professional line, billed mostly by physicians, nurse practitioners, physician assistants and other licensed practitioners. The medicine section runs from vaccines and psychiatry to dialysis, cardiology and therapy. Some of its codes are timed in 15-minute units, others are billed once per session or per test, so the unit matters more here than in most sections.

Practitioners who are not physicians are often paid a reduced percentage of the published amount, so check the schedule for the reduction that applies to your provider type. Physician-fee-schedule codes are billed per service: one unit is one occurrence unless the code itself is defined by time or quantity.

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.
