Medical billing services in Oklahoma
Short answer
Medical billing services in Oklahoma run on a short clock: a SoonerCare fee-for-service claim has to reach the fiscal agent inside six months after the service date, and a denied claim counts as proof of timely filing for a later correction.
Since April 1, 2024 most children, pregnant women and low-income adults are in one of three SoonerSelect health plans on the same six-month rule, while aged, blind and disabled members stay fee-for-service. Commercial clean claims fall under 36 O.S. 1219, personal care and home health claims need matching EVV data, and SoonerRide brokers the rides. A Remitwright dedicated biller works those rules per payer, serving Oklahoma practices remotely. Rules for other states are on the medical billing services by state page.

SoonerCare
SoonerCare is run by the Oklahoma Health Care Authority (OHCA). Fee-for-service claims and provider enrollment go through the SoonerCare Provider Portal1, at www.ohcaprovider.com. A split program: CMS counted 568,493 of Oklahoma's 1,040,358 Medicaid enrollees, 54.6 percent, in full-benefit managed care as of July 1, 2024, three months after the SoonerSelect health plans started, and 751,924 members, 72.3 percent, in some managed care arrangement3. The rest of SoonerCare, including the SoonerCare Choice primary care case management program and SoonerCare Traditional, pays claims through OHCA as fee-for-service.
Fee-for-service filing limit: 6 months from the date of service for a SoonerCare fee-for-service claim to be received by the fiscal agent, for dates of service on or after July 1, 20157. Federal rules cap the window at 12 months, and OHCA's own limit is half of that. A denied claim counts as proof of timely filing, so a claim first filed inside six months can be corrected and refiled after it. Medicare coinsurance and deductible claims must meet Medicare's filing rules and reach SoonerCare within 90 days of the notice of the Medicare disposition. The SoonerSelect health plans and dental benefit managers adjudicate claims under the same OAC 317:30-3-11 limits.
Managed care plans5
- Aetna Better Health of OklahomaSoonerSelect health plan, 186,183 members in CMS's 2024 count
- Humana Healthy Horizons of OklahomaSoonerSelect health plan, 190,134 members in 2024
- Oklahoma Complete HealthSoonerSelect health plan, 191,381 members in 2024, and the SoonerSelect Children's Specialty Program
- DentaQuestSoonerSelect dental plan, 278,611 members in 2024
- Liberty DentalSoonerSelect dental plan, 334,901 members in 2024
Each plan is credentialed separately, has its own portal and its own appeal route. A practice that joins Oklahoma Medicaid through one plan is not in network with the others until each contract is in place.
Commercial payers and the prompt-pay law
Commercial payers active in Oklahoma10: Blue Cross Blue Shield of Oklahoma, Celtic Insurance Company, CommunityCare HMO, Oscar Insurance Company, UnitedHealthcare of Oklahoma. Each has its own filing window, corrected-claim process and appeal levels in its provider manual, and the timely filing limits table lists verified payer deadlines with their sources.
Clean-claim payment window under 36 O.S. § 1219, Oklahoma's prompt pay law: 30 calendar days for electronic clean claims and 45 calendar days for paper clean claims after the insurer receives them9. A clean claim has no defect, impropriety or missing documentation that holds up payment. If a claim is not clean, the insurer must say so in writing within 30 calendar days of receipt and name what it needs. An overdue payment bears simple interest at 10 percent a year, and the prevailing party in litigation can recover attorney fees. The Insurance Department's reach covers health insurers, HMOs and multiple employer welfare arrangements, not self-funded ERISA plans or Medicaid. For an Oklahoma practice, the statute does its work in A/R follow-up: a clean claim still unpaid after the window is escalated with the statute cited, and interest is requested where the law provides it.
NEMT and home care in Oklahoma
Non-emergency medical transportation. SoonerRide: OHCA partners with LogistiCare Solutions LLC to provide non-emergency transportation for SoonerCare Traditional and SoonerCare Choice members, who must call at least three business days before the appointment to book a ride11. The member writes down a confirmation number at booking, scheduling lines run weekdays and Saturdays from 7 a.m. to 6 p.m., and a separate line handles a vehicle that is 15 or more minutes late. The NEMT billing in Oklahoma page covers trip documentation, broker claims and reconciliation.
Electronic visit verification. Mandatory for personal care services, home health care services, self-directed services and live-in caregivers, and SoonerCare pays a claim only when the visit data comes from an OHCA authorized and approved EVV system or aggregator and includes every required verification element12. The rule is OAC 317:30-3-34, revised September 1, 2025, so an unmatched visit is a payment denial, not a documentation request. See home care billing in Oklahoma for waiver programs, EVV exceptions and authorizations.
Rules that change how Oklahoma claims are billed
SoonerSelect moved most SoonerCare members into health plans on April 1, 20244
CMS's 2024 state tables record the SoonerSelect Health Plan as a statewide 1915(b) program that started April 1, 2024, with Maximus as the enrollment broker, after the SoonerSelect Dental Plan started February 1, 2024. Enrollment is mandatory for low-income adults, aged, blind or disabled members and non-disabled children, voluntary for Native American members and children in foster care or adoption assistance, and the full dual eligible column is blank. SoonerCare Choice, the primary care case management program, has run statewide since January 1, 1996 under 1115(a) authority, and SoonerRide has run statewide since June 1, 2006 under section 1902(a)(70) with members pre-assigned to it.
Choice counseling decides which members a plan can hold6
OHCA's choice counseling page lists the groups that are enrolled in SoonerSelect automatically: children, including children in foster care, low-income adults, pregnant women, non-disabled adults aged 19 to 64 and children involved with juvenile justice. Dual eligible members, members with nursing facility needs and Medicare Savings Program beneficiaries are excluded, and American Indian and Alaska Native members may opt in. Members choose between Aetna Better Health of Oklahoma, Humana Healthy Horizons of Oklahoma and Oklahoma Complete Health for health coverage and between DentaQuest and Liberty Dental for dental, and eligible children go to the SoonerSelect Children's Specialty Program.
Plans and dental benefit managers answer to the state's filing and payment rules8
OAC 317:55-5-23, revised September 1, 2024, requires each contracted entity and dental benefit manager to adjudicate provider claims under the timely filing limits in OAC 317:30-3-11 and to meet the claims payment standards in its contract and in 42 CFR 447.45. That means a plan cannot set a shorter window than the state's six months, and a biller aging SoonerSelect claims measures the plan against the federal prompt payment rule as well as the contract.
Two EVV systems and two federal deadlines13
OHCA names Authenticare, the Fiserv system with its own self-registration portal, and HHAeXchange, the managed care platform, as the EVV systems providers use. The agency cites the federal deadlines of January 1, 2019 for personal care services and January 1, 2023 for home health services, and describes the flow: the member's home phone or a smartphone app records the visit, the provider reviews and approves it, and the claim is then submitted electronically for payment. States that miss the requirement lose up to 1 percent of federal matching funds, which is why the edit is a hard one.
