G0120 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 G0120, 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. 5 of the 6 states list more than one rate for G0120, 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 6 states, 1 publish G0120 per p, and 5 schedules print no unit at all (a flat amount per service).
• Per hour. G0120 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 G0120, 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 G0120 run from $0.2706 in Arizona to $151.48 in New Mexico. The two publish it in different units (no unit printed versus P), so part of that gap is the unit rather than the price. Half the states pay more than the median of $79.58 and half pay less. The usual reasons for a spread like this in physician & professional rates:

• 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.
• 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.
• 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 G0120 in 2026, while 2 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 G0120. 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 1 state, the published rate binds plans: a floor, a pass-through or a state-set rate. In 5 states, plans negotiate and the published rate is a benchmark or out-of-network default.

• Plans negotiate; the published rate applies out of network (5 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 (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 New Mexico managed care.

G0120 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.

Physician-fee-schedule codes are billed per service: one unit is one occurrence unless the code itself is defined by time or quantity. 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.
