A4634 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 A4634, 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. 1 of the 5 states list more than one rate for A4634, 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 5 schedules prints a separate unit for A4634, so each amount is a flat payment for one service as the code defines it.
• Per hour. A4634 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 A4634, 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 A4634 run from $1.00 in Kansas to $42.31 in North Dakota, a 42.3x gap in the same unit. Half the states pay more than the median of $36.94 and half pay less. The usual reasons for a spread like this in equipment & supplies rates:

• Many states set equipment and supply fees as a percentage of the Medicare DMEPOS fee schedule, at different percentages and from different years.
• A single code can carry separate purchase, rental and used-equipment amounts, and states publish different subsets of them.
• Some items are priced individually from the manufacturer's price or the supplier's invoice, so fewer states publish a fixed fee.

Timing matters too. 2 states set the current rate for A4634 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.

Most Medicaid members are in managed-care plans, and plans don't publish their provider fee schedules. For A4634, the public signal is the rule each state sets for its plans, recorded on each rate above.

In 1 state, 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 negotiate; the published rate applies out of network (1 state). 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 North Dakota managed care.

A4634 is a HCPCS Level II transportation and supply code in the equipment & supplies line, billed mostly by durable medical equipment suppliers, orthotists, prosthetists and pharmacies. A codes cover ambulance and transportation services and medical and surgical supplies. Transport codes are paid per trip or per mile; supply codes per item or per box as the code states.

Units follow the code: per item, per pair, per box or per month of rental, so a per-unit comparison only holds when the states use the same unit. Pricing modifiers decide which amount applies: NU for a new purchase, RR for a monthly rental and UE for used equipment.

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.
