Medical billing services in Missouri
Short answer
Medical billing services in Missouri sort every MO HealthNet claim by delivery system first: CMS counted 83.6 percent of Missouri Medicaid enrollees in full-benefit managed care in 2024, across Healthy Blue, Home State Health, UnitedHealthcare and the Show Me Healthy Kids specialty plan, while fee-for-service claims go through eMOMED.
Waiver services are carved out to fee-for-service, plan home health stops at 100 visits a year, MTM brokers rides only for fee-for-service participants, and since September 21, 2026 Home State Health denies a home care claim with no matching visit in the state EVV aggregator. A Remitwright dedicated biller works those rules, serving Missouri practices remotely. Rules for other states are on the medical billing services by state page.

MO HealthNet
MO HealthNet is run by the Missouri Department of Social Services (DSS), MO HealthNet Division. Fee-for-service claims and provider enrollment go through eMOMED1, at www.emomed.com. Mostly managed care: CMS counted 1,022,019 of Missouri's 1,222,962 Medicaid enrollees, 83.6 percent, in full-benefit managed care in 20242. Which people go to a plan and which stay in fee-for-service is set by eligibility group, as the rules below explain.
Medicaid filing limit (federal ceiling for fee-for-service claims): No later than 12 months from the date of service, the outer limit 42 CFR 447.45(d)(1) requires every state Medicaid agency, MO HealthNet included, to set for provider claims4. The same federal rule has the agency pay 90 percent of clean claims from practitioners within 30 days of receipt and 99 percent within 90 days, and lets it pay a Medicaid claim tied to a timely Medicare claim within 6 months after the Medicare decision. Managed care plans set their own limits in their provider manuals, so the deadline on a Missouri Medicaid claim depends on which plan holds the member on the date of service.
Managed care plans3
- Healthy Blue
- Home State Health
- UnitedHealthcare
- Show Me Healthy KidsSpecialty plan run by Home State Health
Each plan is credentialed separately, has its own portal and its own appeal route. A practice that joins Missouri Medicaid through one plan is not in network with the others until each contract is in place.
Commercial payers and plan payment standards
Commercial payers active in Missouri6: UnitedHealthcare, Ambetter Health, Anthem Blue Cross and Blue Shield, Medica, Blue Cross and Blue Shield of Kansas City, Oscar Insurance Company. No two of them share a provider manual: filing windows, corrected-claim processes and appeal levels are set payer by payer, and the timely filing limits table lists verified deadlines, each with its source.
For Medicaid managed care, the clean-claim payment standard under 42 CFR 447.46, timely claims payment by MCOs: 90 percent of clean claims from practitioners paid within 30 days of receipt and 99 percent within 90 days, the 447.45 standards every MO HealthNet Managed Care contract must carry unless a plan and its providers write an alternative schedule into the contract5. The date of receipt is the date the payer stamps on the claim and the date of payment is the date of the check or other payment, so a late managed care claim is measured from the plan's own receipt date. Commercial claims follow the carrier contract and Missouri insurance law. In A/R follow-up, a managed care claim that is past that standard is raised with the plan, with the contract term cited.
NEMT and home care in Missouri
Non-emergency medical transportation. Broker for fee-for-service only: MTM is Missouri's NEMT broker for fee-for-service participants under a statewide program CMS lists as starting October 1, 2006, and it carves out mental health services; the three general managed care plans and the Show Me Healthy Kids specialty plan provide NEMT for their own members under their own contracts with MTM3. For a transportation provider that means one MTM relationship but several payer configurations, because the fee-for-service trips and each plan's trips run under different contracts. The NEMT billing in Missouri page covers trip documentation, broker claims and reconciliation.
Electronic visit verification. Open model with a state aggregator: providers choose their own EVV vendor, every system must integrate with the state's EVV Aggregator Solution run by Sandata, and MO HealthNet began requiring EVV for personal care and home health on April 1, 20267. Home State Health's provider notice covers home health nursing, occupational, physical and speech therapy and personal care aide visits, and personal care, advanced personal care, consumer-directed personal care, homemaker, chore and in-home respite services, with no exclusion for live-in caregivers. Since September 21, 2026 a Home State claim must match the member Medicaid ID, dates of service, provider Medicaid ID, procedure code and modifiers and units in the aggregator, or it is denied. See home care billing in Missouri for waiver programs, EVV exceptions and authorizations.
Rules that change how Missouri claims are billed
Eligibility group decides whether a patient is in fee-for-service or a plan1
MO HealthNet assigns each person to fee-for-service or to a managed care plan by eligibility group. Seniors 65 and older, people with a disability, blind or visually impaired adults and women under 65 with breast or cervical cancer stay in fee-for-service; pregnant women and their newborns, children up to 18, parents with children in the home and adults 19 to 64 without a disability go to a plan. Every plan serves every county and covers the same services, so the eligibility group on the eMOMED response, not the patient's address, tells a biller which payer gets the claim.
Waiver services are carved out of managed care, and home health inside the plans stops at 100 visits3
CMS's 2024 state tables record that Missouri's 1915(c) home and community-based waiver services are not covered by the managed care plans at all: every waiver service is carved out and billed fee-for-service. Home health delivered through managed care is limited to 100 visits a year and intended as short-term coverage. An agency that serves both waiver and managed care members in Missouri ends up keeping two billing tracks for the same client population, with the fee-for-service track also carrying the state EVV and MTM rules.
Since September 21, 2026 Home State Health denies claims with no matching EVV visit7
Home State Health's provider notice makes EVV a claims edit: a claim for a personal care or home health service must match a verified visit in the state EVV Aggregator Solution on member Medicaid ID, dates of service, provider Medicaid ID, procedure code and modifiers, and units billed, or it is denied. The notice names the failure modes a biller will see: the provider is not using EVV, the EVV vendor is not sending visits to the aggregator, the visits in the aggregator are not in a verified status, or the claim went out before the vendor sent the visit. Providers are told to check the aggregator at least weekly and to align claims to visit data before submission.
MTM covers fee-for-service rides, and each plan buys its own transportation from MTM3
Missouri's NEMT broker, MTM, only covers fee-for-service participants and carves out mental health transportation, while Home State Health, UnitedHealthcare, Healthy Blue and the Show Me Healthy Kids specialty plan provide NEMT for their members under their own MTM contracts. The NEMT program is statewide and CMS lists its start as October 1, 2006. A transportation company reconciles trips against the payer that authorized them, not against a single statewide trip list.
Managed care is mandatory for most groups and voluntary for aged, blind or disabled members3
CMS's 2024 state tables record MO HealthNet Managed Care as a statewide program running since September 1, 1995 under 1115(a), 1915(b) and 1932(a) authority, with Automated Health Systems as the enrollment broker. Enrollment is mandatory for low-income adults, non-disabled children and children in foster care or adoption assistance, and voluntary for aged, blind or disabled members and for children with special health care needs. A person found eligible for managed care is assigned to a health plan automatically on the date the state makes that determination and then has 90 calendar days from the initial enrollment effective date to change plans without cause. For a practice that means the plan on the eligibility response can change inside the first three months, so a biller checks eligibility on each date of service rather than once at intake.
eMOMED holds the claim, the attachment and the eligibility work in one place1
MO HealthNet's April 2026 provider training describes eMOMED as the Division's billing portal: providers submit and search claims by ICN, check participant eligibility and annual renewal dates, look up prior authorization status, read payment information and provider enrollment status, and send claim attachments such as the sterilization consent form, the hysterectomy acknowledgment, the second surgical opinion form and certificates of medical necessity. The General Sections provider manual applies to every fee-for-service program, with Section 4 on timely filing, Section 5 on third party liability and Section 6 on adjustments.
