G0429 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 G0429, 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. 7 of the 10 states list more than one rate for G0429, 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 10 schedules prints a separate unit for G0429, so each amount is a flat payment for one service as the code defines it.
• Per hour. G0429 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 G0429, 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 G0429 run from $19.45 in Kansas to $93.61 in South Dakota, a 4.8x gap in the same unit. Half the states pay more than the median of $77.60 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.
• 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.
• Some states pay physician services as a percentage of the Medicare fee schedule; others keep a schedule of their own that may not have been rebased for years.

Timing matters too. 9 states set the current rate for G0429 in 2026 or later, while 1 state 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 G0429 is negotiated privately, but the state decides how much room there is to negotiate. Here is how the rules break down across the 10 states.

In 4 states, plans negotiate and the published rate is a benchmark or out-of-network default. The rule for the remaining 6 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.

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 South Dakota managed care.

G0429 is a HCPCS Level II professional services code in the physician & professional line, billed mostly by physicians, nurse practitioners, physician assistants and other licensed practitioners. G codes describe professional services and procedures that have no CPT code, or that payers define more narrowly. Many are timed, so check the unit before comparing.

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

Medicare's 2026 physician fee schedule pays $91.96–$112.17 for G0429 (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.
