Behavioral health payers in North Carolina

North Carolina's commercial market is led by a dominant statewide Blue — Blue Cross and Blue Shield of North Carolina (Blue Cross NC) — with the national carriers competing across the state: UnitedHealthcare, whose behavioral health is administered by Optum, so a facility pursuing “a UnitedHealthcare contract” is in practice pursuing an Optum contract; Aetna, which manages behavioral health in-house with no separate brand; and Cigna, whose behavioral health contracts run through Evernorth Behavioral Health. The state's distinctive feature is a notable regional rental-network presence. MedCost is not a traditional insurer but a regional PPO network and third-party administrator serving employers across North Carolina, South Carolina, and Virginia — owned since mid-2025 by Health Plans Inc., part of the Harvard Pilgrim / Point32Health family. Facilities contract with MedCost's network, which self-funded employer plans then rent, which is why the MedCost name appears on claims from many different employers. Behavioral health arrangements vary by employer plan — some clients route behavioral health through dedicated behavioral health networks rather than MedCost's own — so what a facility can contract for depends on the specific plan. Medicaid is a separate contracting world again, with its own rate structures and processes. The practical rule holds here as everywhere: the entity that holds your contract, not the brand on the member's card, sets the rate.

By level of care, on facility codes — the same as everywhere else. A North Carolina facility contract is a schedule of level-specific rates: a per diem for detox, a per diem for residential, a program rate for partial hospitalization and for intensive outpatient, each keyed to a revenue code and an HCPCS code on the facility claim and each priced on its own terms. The professional work delivered inside those days bills separately, on a clinician fee schedule. Some payers require the revenue code and the HCPCS code together for a claim to price; others key the rate on one or the other. Nothing about that structure is specific to North Carolina; which code carries which level is covered on the level-of-care hubs and the billing-code pages.

North Carolina publishes state Medicaid fee schedules for its programs. Those schedules are public, uniform, and not negotiated: a price per billing code set by the state agency, the same for every enrolled provider billing the fee-for-service program. Because they are easy to find, a North Carolina Medicaid figure is often the first “rate” a searcher sees for a code like H0010 or H0018 — and for a commercially contracted facility it is the wrong number. What the schedule says is the lowest rate a public program has set for that service in North Carolina. What it does not say is what commercial payers pay facilities like yours, and it is not a ceiling either. Nor does it say what a Medicaid managed-care plan pays: an MCO pays under its own arrangements, which may reference the state schedule, sit at it, or differ from it. TierBench carries the North Carolina state Medicaid fee schedule as a reference floor beneath the commercial distribution for the same code — the “Medicaid floor” line in Ratebench. That is a reference schedule, not Medicaid MCO negotiated rates, which we do not hold and do not represent as coverage.

Four things, before your program's own case is made. The contracting entity: Optum for UnitedHealthcare members, Aetna directly, Evernorth for Cigna, the Blue for its own members, or — for a MedCost-rented plan — MedCost's network, with the employer plan behind it deciding whether behavioral health even routes there; each prices a level of care against its own network. The market: the same level of care is paid differently from one market to another — even within one state, and North Carolina has several distinct ones. The vintage: a per diem negotiated years ago and never revisited sits where the market was then. And the structure: a straight per diem, a case rate covering the episode, or a percent of charges produce different economics for the same care and cannot be compared as one number. Product line matters too — commercial HMO/PPO, a self-funded employer plan on a rented network, and a Medicare Advantage product may each sit with a different administrator and a different schedule. The payer pages spell out those drivers book by book.

Detox. A sub-acute detox day in a residential addiction program goes out on revenue code 0126 with H0010 as the HCPCS line. It is the most acute facility level a North Carolina program contracts for, and it is one of the two levels where the North Carolina Medicaid schedule prices a public floor beneath the commercial distribution.

Residential. A residential day goes out on an accommodation revenue code — 1001 psychiatric, 1002 chemical dependency — with H0018 (short-term, non-hospital program) or H0017 (hospital-based program) as the per-diem line; which code a payer expects is a contract and billing-rule question. Because the code is defined by level of care rather than by condition, substance-use, mental-health, and eating-disorder residential programs bill the same line, with the diagnosis in the claim's ICD coding. Residential is the other level where the North Carolina Medicaid schedule sits beneath the commercial distribution as a reference floor.

Partial hospitalization. A PHP day goes out on revenue code 0912 or 0913 with H0035; in contracting practice H0035 functions as the partial-hospitalization level-of-care line, and payers' billing rules decide which programs bill it.

Intensive outpatient. An IOP day goes out on revenue code 0905 or 0906 with H0015. What the rate is a rate for depends on how the contract defines the program day — the code set's three-hours, three-days floor is a minimum a contract may define above.

Level by level, against comparable facilities in North Carolina on the same code with the same payer, read as a percentile position — never a blended average, and never a public price list. North Carolina is one of the four states where TierBench's facility coverage is deepest. Two regional books are specific to the state: MedCost, a regional network with facility-level behavioral health rates across the levels of care, and a separate UnitedHealthcare facility slice for North Carolina. That UnitedHealthcare book is a distinct regional slice, not Optum's national behavioral health network — TierBench keeps the two apart, and a facility should not read a North Carolina UnitedHealthcare rate as an Optum rate, or the reverse. The national behavioral health networks that operate in the state are captured at the facility level. Beneath the commercial distribution, the North Carolina Medicaid fee schedule sits as a reference floor for detox and residential codes. Ratebench and Peerbench do this on actual negotiated rates from payers' Transparency in Coverage files, resolved to the facility and scored for confidence.
