G0446 Medicaid reimbursement rate by state (2026)

• Order. States are listed from the highest published rate to the lowest. A like-for-like rank only counts states that use the same unit: 11 of the 11 states publish G0446 per 15 min, enough to rank them against each other.
• Medicaid rate. The most the state's fee-for-service program pays for one unit, as published. 7 of the 11 states list more than one rate for G0446, 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. All 11 states publish G0446 per 15 min, so the amounts compare directly.
• Per hour. Time-based units are converted to an hour of service (four 15-minute units make an hour). 11 of the 11 states bill G0446 by time, with a median of $87.12 per hour.
• 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 G0446, 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 G0446 run from $3.95 in Kansas to $47.89 in Montana, a 12.1x gap in the same unit. Half the states pay more than the median of $21.78 per 15 min 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.
• 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.
• 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. 7 states set the current rate for G0446 in 2026 or later, while 3 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 G0446. 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 4 states, the published rate binds plans: a floor, a pass-through or a state-set rate. In 3 states, plans negotiate and the published rate is a benchmark or out-of-network default. The rule for the remaining 4 states is not classified yet.

• Plans must pay at least the published rate (4 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.
• Plans negotiate; the published rate applies out of network (3 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 Montana managed care.

G0446 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 $32.18–$41.26 for G0446 (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.
