Medicaid Billing Services

Medicaid billing services

Medicaid billing services bill the state program and its managed care plans under the rules each one sets: state enrollment kept active for every provider, plan-by-plan authorization and filing rules followed, other coverage billed first because Medicaid pays last, and every remit reconciled against the state or plan rate.

State and plan rules for your specialty, in one sheet. No patient data needed.

Most of the detail lives in the state provider manual and each MCO's provider guide, so the work starts by reading both.

This is part of getting the claim out clean. Buy it on its own or pair it with our other billing services, stage by stage.

What Medicaid billing covers

State Medicaid enrollment for every billing, rendering, ordering and referring provider the state must have on file, with revalidation on the state's cycle

Managed care plan enrollment on top of state enrollment, because federal rule requires the state to screen and enroll every MCO network provider too

Third party liability checked before billing: Medicare, employer plans and other coverage are billed first and the primary remit travels with the Medicaid claim

Authorization, unit and visit limits checked against the specific plan's rules, which can differ from fee-for-service rules for the same code

The state's and each plan's filing limits tracked separately, with the federal outer limit of 12 months from the date of service as the backstop

Remits posted from each plan's 835, denials routed by CARC and RARC, and plan dispute deadlines logged

EVV exceptions cleared before personal care and home health claims are billed, so a missing clock-in does not become a denial

NEMT trip claims billed to the state or its broker, depending on how your state meets its transportation assurance

Plan payments reconciled against the contracted schedule, with short-paid lines listed for dispute

What goes wrong when Medicaid billing is skipped

Contracted with the plan, never enrolled with the state

A therapist signs with a Medicaid managed care plan, gets a plan provider number and starts billing. The state is required to screen and enroll every network provider of its MCOs, and when the plan matches its roster against the state file, claims start denying for a provider the state does not recognize.

Medicaid billed first when the patient had Medicare

A dual-eligible patient is billed to Medicaid as if it were the only coverage. Medicaid is the payer of last resort: where other liability is probable the agency rejects the claim and returns it, or pays and recovers later, and the Medicare filing year has been running the whole time.

One filing calendar for five payers

The state allows twelve months, so the practice assumes every plan does. Each plan's contract sets its own filing and dispute windows, and claims for one plan sit past that window and are lost on timing alone.

How we run Medicaid billing

Read the rules

The state provider manual, the fee schedule and each plan's provider guide for your specialty, turned into a one-page rule sheet per payer.

Enroll

State enrollment and revalidation for every provider, then each plan's network application. Claims for a plan are held until its effective date.

Verify

Eligibility checked by plan, not just by program, with other coverage, authorization and (for home care) EVV status confirmed before billing.

Bill and post

Claims go out through your clearinghouse or the state portal, and each 835 is compared with the rate you should have been paid.

Dispute and reconcile

Denials and short payments go back through the plan's own dispute process, inside its window, and the reconciliation shows what is still owed.

What you receive every week

Payer rule sheet

One page per plan and for the state program: enrollment status, authorization rules, filing and dispute windows, portal and contact.

Weekly Medicaid report

Claims sent, paid, denied and short-paid by plan, with open authorizations, EVV exceptions and plan disputes listed with their deadlines.

Enrollment and revalidation tracker

Every provider against the state and each plan: status, effective date, revalidation due date and what each pending item is waiting on.

Worked example: a behavioral health group in a managed care state

A hypothetical counseling group of six clinicians bills the state program and three Medicaid managed care plans. Two clinicians were added to the plans but never enrolled with the state, and one plan begins denying their claims. The state applications go in, the affected claims are held with their filing deadlines logged, and the plan's rule sheet gets a line: state enrollment first, plan roster second. When the state effective dates arrive, the held claims are released.

Questions about Medicaid billing

Do we have to enroll with the state if we only bill Medicaid managed care plans?

Yes. Under 42 CFR 438.602 the state must screen, enroll and periodically revalidate all network providers of its MCOs, PIHPs and PAHPs. The same rule says this does not make you serve fee-for-service patients. In practice the plan checks its roster against the state file, so the state application comes first.

What is the Medicaid timely filing limit?

Federal rule (42 CFR 447.45) requires states to make providers submit claims no later than 12 months from the date of service. States can set shorter limits, and each managed care plan sets its own window in its contract, so every payer you bill gets its own limit.

How quickly does Medicaid have to pay a clean claim?

42 CFR 447.45 defines a clean claim as one that can be processed without obtaining more information from the provider or a third party. The state must pay 90 percent of clean practitioner claims within 30 days of receipt and 99 percent within 90 days. Under 42 CFR 447.46 the MCO contract must carry the same standards unless the plan and the provider agree an alternative payment schedule in the contract.

What does payer of last resort mean for our claims?

All other available coverage must pay first: group health plans, Medicare, workers' compensation, liability settlements and more. When probable third party liability is known at filing, the agency rejects the claim and returns it to the provider, which is why other coverage is found before billing.

How often does Medicaid revalidation happen?

Federal rule requires the state to revalidate every enrolled provider at least every five years (42 CFR 455.414). Your state sets the exact cycle and process, and the due dates sit in your tracker from the day enrollment is approved.

Can you appeal a Medicaid managed care denial?

Yes, by two paths. A service denied to the member is an adverse benefit determination: the member has 60 calendar days from the notice to appeal, the plan may have only one level of appeal, and a provider can file for the member with written consent (42 CFR 438.402). A payment dispute goes through the plan's provider dispute process.

Do you handle EVV and NEMT Medicaid claims?

Yes. Electronic visit verification applies to Medicaid personal care services and home health services under section 12006 of the 21st Century Cures Act, and EVV exceptions are cleared before those claims go out. For transportation, the state must ensure necessary transportation for beneficiaries (42 CFR 431.53) and many states do that through a broker, so trips are billed to whichever entity your state uses.

How do you know which Medicaid plans matter in our state?

Your remits show most of it. For the rest we use the plan-level data CMS publishes in its Medicaid Managed Care Enrollment Report and your state agency's plan list, and each plan you bill gets its own rule sheet.
