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 A9526, 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. 7 of the 18 states list more than one rate for A9526, 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 18 states, 1 publish A9526 per percent of billed charges, and 17 schedules print no unit at all (a flat amount per service).
  • Per hour. A9526 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 A9526, 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 A9526 rates differ between states

Published rates for A9526 run from $1.00 in Kansas to $826.39 in Washington, a 826.4x gap in the same unit. Half the states pay more than the median of $626.21 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. 9 states set the current rate for A9526 in 2026 or later, while 5 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 A9526

No managed-care plan publishes what it pays for A9526. 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 4 states, the published rate binds plans: a floor, a pass-through or a state-set rate. In 8 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 (8 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 Washington managed care.

Billing

Units and billing for A9526

A9526 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.

Pricing modifiers decide which amount applies: NU for a new purchase, RR for a monthly rental and UE for used equipment. 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.

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.
