How to read this table
- Order. States are listed from the highest published rate to the lowest. No single unit is shared by 8 or more states for G6003, 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. 2 of the 7 states list more than one rate for G6003, 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 7 states, 1 publish G6003 per unit, and 6 schedules print no unit at all (a flat amount per service).
- Per hour. G6003 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 G6003, 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.
Why G6003 rates differ between states
Published rates for G6003 run from $96.70 in Michigan to $148.61 in New Mexico, a 1.5x gap in the same unit. Half the states pay more than the median of $122.33 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.
- 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.
Timing matters too. 1 state set the current rate for G6003 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.
What managed-care plans pay for G6003
What a plan pays for G6003 is negotiated privately, but the state decides how much room there is to negotiate. Here is how the rules break down across the 7 states.
In 1 state, 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.
- 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 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.
Units and billing for G6003
G6003 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. 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.
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.
