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 Q5142, 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. 4 of the 15 states list more than one rate for Q5142, 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 15 states, 1 publish Q5142 per unit, and 14 schedules print no unit at all (a flat amount per service).
  • Per hour. Q5142 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 Q5142, 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 Q5142 rates differ between states

Published rates for Q5142 run from $5.30 in Texas to $93.75 in Wisconsin, a 17.7x gap in the same unit. Half the states pay more than the median of $12.98 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.
  • Primary-care and pediatric add-ons, enhanced rates for certain specialties and targeted increases for access problems change individual codes without moving the rest of the schedule.
  • Each state sets its own physician conversion factor or fee for every code, and many update them on a state budget cycle rather than on Medicare's calendar.

Timing matters too. 7 states set the current rate for Q5142 in 2026 or later. 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 Q5142

Most Medicaid members are in managed-care plans, and plans don't publish their provider fee schedules. For Q5142, the public signal is the rule each state sets for its plans, recorded on each rate above.

In 5 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 2 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.
  • The state sets the plan rate (1 state). There is little to negotiate on price. Contracting is about network participation, authorization and billing terms.

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 Wisconsin managed care.

Billing

Units and billing for Q5142

Q5142 is a HCPCS Level II temporary code in the physician & professional line, billed mostly by physicians, nurse practitioners, physician assistants and other licensed practitioners. 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.

Physician-fee-schedule codes are billed per service: one unit is one occurrence unless the code itself is defined by time or quantity. Where a state publishes separate facility and non-facility amounts, the non-facility (office) amount is usually higher because the practice carries the overhead.

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.
