Guide

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 J9213, 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 16 states list more than one rate for J9213, 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 16 schedules prints a separate unit for J9213, so each amount is a flat payment for one service as the code defines it.
  • Per hour. J9213 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 J9213, 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.
Context

Why J9213 rates differ between states

Published rates for J9213 run from $29.65 in District of Columbia to $407.24 in Maine, a 13.7x gap in the same unit. Half the states pay more than the median of $40.53 and half pay less. The usual reasons for a spread like this in pharmacy rates:

  • 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.
  • For children, many vaccines are supplied through the federal Vaccines for Children program, so the Medicaid payment can be for administration only.

Timing matters too. 1 state set the current rate for J9213 in 2026 or later, while 9 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.

Managed care

What managed-care plans pay for J9213

Most Medicaid members are in managed-care plans, and plans don't publish their provider fee schedules. For J9213, the public signal is the rule each state sets for its plans, recorded on each rate above.

In 4 states, 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. The rule for the remaining 6 states is not classified yet.

  • 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 (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.

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.

Billing

Units and billing for J9213

J9213 is a HCPCS Level II drug code in the pharmacy line, billed mostly by practices and clinics that administer vaccines and drugs. J codes cover drugs that are not self-administered. One unit is the dose stated in the code, so a claim for a larger dose bills several units.

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

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.
