T5999 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 T5999, 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 11 states list more than one rate for T5999, 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 11 states, 1 publish T5999 per per item, 1 per decremental, 1 per 15 min and 1 in other units, and 7 schedules print no unit at all (a flat amount per service).
• Per hour. Time-based units are converted to an hour of service (four 15-minute units make an hour). 1 of the 11 states bill T5999 by time.
• 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 T5999, 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 T5999 run from $0.56 in Hawaii to $3,000.00 in North Dakota. The two publish it in different units (Per Item versus no unit printed), so part of that gap is the unit rather than the price. Half the states pay more than the median of $10.00 and half pay less. The usual reasons for a spread like this in other home & community services rates:

• Case management may be paid as a monthly rate, a per-contact rate or in 15-minute units.
• Home and community-based services are often paid under waivers, and each waiver can set its own rate for the same service.
• Some services are paid per 15 minutes in one state and per day or per month in another.

Timing matters too. 2 states set the current rate for T5999 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.

Most Medicaid members are in managed-care plans, and plans don't publish their provider fee schedules. For T5999, the public signal is the rule each state sets for its plans, recorded on each rate above.

In 1 state, the published rate binds plans: a floor, a pass-through or a state-set rate. In 4 states, plans negotiate and the published rate is a benchmark or out-of-network default. In 2 states, the service is paid outside the plans or through a state-directed payment. The rule for the remaining 4 states is not classified yet.

• Plans negotiate; the published rate applies out of network (4 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.
• Paid by the state, outside the plans (2 states). Bill the state's Medicaid program, not the plan, at the published rate. There is no plan contract to negotiate for this service.
• 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 North Dakota managed care.

T5999 is a HCPCS Level II state Medicaid agency code in the other home & community services line, billed mostly by case management agencies, adult day centers, respite providers and other home and community-based services. T codes were created for state Medicaid agencies, for services such as personal care, private duty nursing, case management and waiver services. Each state defines how the code is used and paid, so units vary from 15 minutes to a month.

Units range from 15 minutes to a day or a month, 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.
