Medicaid payer matrix worksheet
A downloadable CSV template for building a Medicaid payer matrix: one row per Medicaid payer or managed care plan a practice works with, capturing the program model, enrollment status, accepted claim format, filing window, authorization rules, and coordination-of-benefits posture in one reference grid. Because Medicaid is administered state by state and split between fee-for-service and managed care organizations, nearly every operational rule varies by state, plan, and contract; this worksheet is a structure for recording each payer's actual published rules, not a source of those rules. Confirm every value against the responsible state Medicaid agency or the specific managed care plan, and against the authoritative federal sources below. Example rows use non-identifying placeholders only. This is a neutral educational reference and does not capture, transmit, or store protected health information.

Column guide
Payer / plan name
Name of the Medicaid payer or managed care plan as it appears in enrollment and remittance records. Use the exact plan name, since a single state may contract with several managed care organizations (MCOs) that each set their own operational rules.
Program model
Whether claims for this payer run through fee-for-service (FFS) billed to the state, or through a managed care organization (MCO). This distinction determines who adjudicates the claim and which rule set applies; see the fee-for-service and managed care organization glossary entries.
State / program
The state Medicaid program (and any sub-program such as CHIP or a specialty carve-out) governing this payer. Medicaid is jointly funded federally and administered by each state, so record the specific state whose rules apply; confirm details with that state's Medicaid agency.
Provider enrollment status
Provider enrollment or Medicaid provider ID status for this payer (for example enrolled, pending, or revalidation due). Medicaid requires provider enrollment before payment; see the provider enrollment glossary entry and confirm requirements with the state agency.
Claim format
The claim format this payer accepts, such as the CMS-1500 professional form, the UB-04 institutional form, or the electronic 837 transaction. Record what the payer's published billing guidance specifies rather than assuming a universal default.
Timely filing window
The filing deadline this payer publishes, as a placeholder to record the payer's stated value. Timely filing limits vary by state and by plan; do not assume a standard figure. Enter the value from the payer's published rules and cite the source (see the timely filing glossary entry).
Prior authorization scope
Which services this payer requires prior authorization for, and where requests are submitted. Authorization requirements vary by payer, plan, and service; record the payer's published list rather than a general rule (see the prior authorization glossary entry).
COB / third-party liability
Coordination-of-benefits and third-party liability posture for this payer. Medicaid is generally the payer of last resort, so record how other coverage must be billed first; confirm the specific process with the state agency (see the payer of last resort glossary entry).
Portal / contact
Provider portal, clearinghouse identifier, or provider-services contact for this payer. Record where eligibility checks, claim status, and authorization requests are handled for this plan.
Source & date verified
The authoritative source consulted for this row's rules (state Medicaid agency, plan provider manual, or a federal source) and the date the values were last confirmed. Payer rules change, so re-verify periodically and keep this field current.
Fictional example
| Payer / plan name | Program model | State / program | Provider enrollment status | Claim format | Timely filing window | Prior authorization scope | COB / third-party liability | Portal / contact | Source & date verified |
|---|---|---|---|---|---|---|---|---|---|
| Example State Medicaid (FFS) | Fee-for-service (FFS) | Example State — Medicaid | Enrolled — revalidation due next cycle | CMS-1500 / 837P | Per state published limit — verify | Select outpatient services — verify list | Bill known primary coverage first; last resort | State Medicaid provider portal | State Medicaid agency — verify current date |
| Example Managed Care Plan | Managed care organization (MCO) | Example State — Medicaid MCO | Pending plan enrollment | UB-04 / 837I | Per plan provider manual — verify | Inpatient and specialty services — verify | Report other coverage to plan; COB per contract | Plan provider services portal | Plan provider manual — verify current date |
Working instructions
- 1Add one row per Medicaid payer or managed care plan the practice bills, and treat every rule field (filing window, authorization scope, claim format, COB) as a placeholder to be filled from that payer's own published guidance, since these vary by state, plan, and contract.
- 2Verify each value against the responsible state Medicaid agency and the specific plan's provider manual, plus the federal sources cited below; record the source and verification date in the final column and re-check periodically because payer rules change.
- 3Do not store protected health information (PHI) in this worksheet or in any unsecured copy of it; keep the matrix limited to payer-level rules and use only non-identifying placeholders, never patient names, identifiers, or claim-level detail.
- 4Use the program model and coordination-of-benefits columns together to route claims correctly, confirming fee-for-service versus managed care adjudication and payer-of-last-resort sequencing for each payer before submission.
