Q2004 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 Q2004, 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. Each state lists a single rate for Q2004.
• Unit. None of the 8 schedules prints a separate unit for Q2004, so each amount is a flat payment for one service as the code defines it.
• Per hour. Q2004 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 Q2004, 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 Q2004 run from $4.84 in Utah to $146.92 in Maine, a 30.4x gap in the same unit. Half the states pay more than the median of $61.78 and half pay less. The usual reasons for a spread like this in pharmacy rates:

• For children, many vaccines are supplied through the federal Vaccines for Children program, so the Medicaid payment can be for administration only.
• States differ in whether they pay a fixed fee, a percentage of a benchmark or invoice cost.
• Drugs given in a practice or clinic are commonly priced from a benchmark such as average sales price or wholesale acquisition cost, which moves every quarter.

Timing matters too. 2 states set the current rate for Q2004 in 2026 or later, while 4 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 Q2004. 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 7 states, plans negotiate and the published rate is a benchmark or out-of-network default. The rule for the remaining 1 state is not classified yet.

• Plans negotiate; the published rate applies out of network (7 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 Maine managed care.

Q2004 is a HCPCS Level II temporary code in the pharmacy line, billed mostly by practices and clinics that administer vaccines and drugs. Q codes are temporary codes for drugs, biologicals, supplies and services. The unit depends on the code and is often a dose or an item.

Many states require the National Drug Code (NDC) on the claim alongside the billing code. Drug codes are billed in units of the dose stated in the code, so a larger dose bills more units.

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.
