99355 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 99355, 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. 6 of the 11 states list more than one rate for 99355, 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 11 states, 2 publish 99355 per 30 min, and 9 schedules print no unit at all (a flat amount per service).
• Per hour. 99355 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 99355, 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 99355 run from $16.10 in Rhode Island to $97.90 in Illinois, a 6.1x gap in the same unit. Half the states pay more than the median of $79.23 and half pay less. The usual reasons for a spread like this in physician & professional rates:

• 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.
• 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.
• Primary-care and pediatric add-ons, enhanced rates for certain specialties and targeted increases for access problems change individual codes without moving the rest of the schedule.

Timing matters too. None of the states changed its rate for 99355 in 2026, while 9 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.

No managed-care plan publishes what it pays for 99355. What is public is the rule each state's plan contracts set, and that rule decides how much the published rate matters when you contract with a plan.

In 2 states, the published rate binds plans: a floor, a pass-through or a state-set rate. In 6 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 (6 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 are expected to pay at least the published rate (1 state). Treat the published rate as a strong anchor, and confirm the minimum is written into your own plan agreement.
• 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 Illinois managed care.

99355 is a CPT evaluation and management code in the physician & professional line, billed mostly by physicians, nurse practitioners, physician assistants and other licensed practitioners. Evaluation and management codes are billed once per visit. The code itself sets the level of the visit, so there is no time unit to multiply, and the setting (office, hospital, facility) decides which code applies.

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. Where a state publishes separate facility and non-facility amounts, the non-facility (office) amount is usually higher because the practice carries the overhead.

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.
