How to Bill MetroPlusHealth: 2026 Prior Auth and Claims Guide

:::info Quick answer To get a MetroPlus prior authorization, submit requests via the MetroPlus Provider Portal at least 14 days before elective services. Advanced imaging routes through EviCore. Standard determinations take up to 14 days, while expedited requests process within 72 hours under 2026 NYS DOH guidelines. :::

If you bill in the five boroughs of New York City, you already know MetroPlusHealth. As the captive managed care plan for NYC Health + Hospitals, they handle a massive chunk of New York's Medicaid, Essential Plan, Child Health Plus, and Medicare Advantage volume. But raw patient volume doesn't automatically translate to easy revenue. Getting paid by MetroPlus requires military precision, especially when dealing with their rigid clinical edits and tight filing windows.

New York State has heavily regulated managed care timelines, but payer implementation always varies. In 2026, MetroPlus relies on a mix of direct portals and third-party carve-outs to gatekeep expensive procedures and specialty medications. You cannot afford to guess when an auth is required. Missing a step means eating the cost of the procedure. Here is exactly how to manage MetroPlus claims, from the first eligibility check to the final appeal.

How This Payer Works

MetroPlus is functionally a Medicaid Managed Care Organization (MCO) with several commercial and Medicare offshoots. Because they are so closely tied to NYC Health + Hospitals, they heavily favor in-network utilization at H+H facilities. If you operate an independent specialty practice, expect tight scrutiny on referrals and outpatient procedures.

Before you treat, you need to clear the specific MetroPlus prior authorization requirements for the patient's exact plan type. Medicaid has different clinical guardrails than the Essential Plan or Medicare Advantage. You handle most medical and surgical auths directly through the MetroPlus Provider Portal. You must submit clinical notes, conservative treatment histories, and relevant imaging directly in the portal. Faxing a static form to a generic 800-number is a recipe for a "lost in transit" denial.

For advanced imaging (MRI, CT, PET) and specialized musculoskeletal (MSK) procedures, MetroPlus offloads the decision-making to EviCore. If a provider orders a lumbar MRI (CPT 72148), your front desk must log into the EviCore portal, not MetroPlus, to initiate the request. EviCore will demand six weeks of conservative therapy documentation—usually physical therapy notes and NSAID prescriptions. If the physician failed to document that conservative treatment failed, EviCore kicks the request back automatically.

Physician-administered drugs (J-codes) remain a major pain point. While New York State fully transitioned the Medicaid pharmacy benefit back to fee-for-service under the NYRx initiative, that carve-out applies strictly to retail pharmacy prescriptions. If your doctor injects Stelara (J3358) or Prolia (J0897) in the office, you still bill MetroPlus on an 837P or CMS-1500, and you still need a medical benefit authorization from MetroPlus. Do not let a confused front-desk worker tell a patient that "Medicaid covers it now."

Enrollment and Credentialing

You cannot simply get an NPI and start billing MetroPlus. They are legally barred from paying you unless you are actively enrolled with New York State Medicaid.

First, you must complete the NYS Department of Health (DOH) Medicaid enrollment process to get an active MMIS Provider ID. Under the 21st Century Cures Act, every rendering provider—even if they only see Medicare Advantage or commercial patients for MetroPlus—must be screened and enrolled by the State. EMEDNY handles this. If your doctor's MMIS profile lapses because they ignored a revalidation letter, MetroPlus will deny all claims with remark code N272 (Missing/incomplete/invalid referring provider identifier) or N253 (Missing/incomplete/invalid attending provider identifier).

Once the state approves your MMIS ID, MetroPlus uses CAQH ProView for the actual credentialing. Ensure the provider's CAQH profile is fully updated, attested, and explicitly authorizes MetroPlus to view the data.

The credentialing committee at MetroPlus typically meets monthly. From the day you submit a clean roster addition request to the day you receive the welcome letter and effective date, expect a 90-to-120-day lag. They do not retroactively credential. If you bill for a date of service (DOS) prior to the official credentialing effective date, the claim will pay at the out-of-network rate, which for MetroPlus Medicaid HMO usually means a flat zero dollars. Keep your roster meticulously updated. When a doctor leaves the practice, notify MetroPlus immediately. Failing to update your directory data can result in compliance penalties under the federal No Surprises Act and 2026 CMS directory mandates.

Claim Submission and Timelines

MetroPlus accepts electronic claims via most major clearinghouses (Availity, Change Healthcare/Optum, Waystar). The MetroPlus electronic Payer ID is typically 13265, though you should always verify the routing with your specific clearinghouse, especially for Medicare Advantage claims which occasionally route differently based on behavioral health carve-outs.

If you drop paper claims—which you should only do when submitting primary EOBs for complex coordination of benefits—mail them to the specific PO Box listed on the back of the patient's current ID card. Never send medical records attached to an initial paper claim unless the CPT code mandates it (e.g., unlisted codes like 29999). It slows down optical character recognition (OCR) scanning and gets the claim routed to manual review.

Timely filing is unforgiving. You must know exactly which plan you are billing.

When a claim rejects at the clearinghouse level (a 277CA rejection), it never reached MetroPlus. You must fix the EDI loop error—usually a missing zip code extension or an invalid subscriber ID—and resend. This does not buy you more timely filing days. The 90-day clock keeps ticking until MetroPlus generates an internal claim control number (CCN).

Denials and Appeals

When a claim hits your remittance advice (RA) with a zero payment, you need to act fast. MetroPlus uses standard ANSI denial codes, but their internal rationale is often tied to restrictive local coverage policies.

The most common pain point is CO-197 (Precertification/authorization absent). If you forgot to get an auth, MetroPlus rarely grants retroactive approvals. You can only win a retro-auth appeal if you prove the patient presented in an emergency state, or if the patient gave you the wrong insurance card on the date of service and you billed the correct payer within 30 days of discovering the error. "Administrative oversight" by your front desk is not a valid appeal reason.

For clinical denials—when they deny a service as experimental or not medically necessary—you have two distinct paths: a peer-to-peer review or a formal appeal.

If MetroPlus denies an authorization request before the service, schedule a peer-to-peer (P2P) review immediately. In 2026, you generally have 14 days from the date of the initial denial letter to conduct a P2P. Your requesting physician must speak directly with the MetroPlus medical director. Equip your doctor with the exact local coverage determination (LCD) or Medicaid policy number before they get on the phone. Do not let them argue general medicine; they need to argue policy criteria.

If the service is already rendered and denied on the RA, you must file a Level 1 Provider Appeal. You have 60 days from the date of the RA. Print out the MetroPlus Provider Appeal Form from their website. Attach the RA, the original claim, the complete medical record, and a cover letter detailing why the denial was incorrect. Highlight the clinical notes. If the appeal is upheld (denied again), you have 60 days to file a Level 2 appeal, which is reviewed by a different medical director who was not involved in the initial determination.

Never batch appeals. If you have ten patients denied for the exact same coding issue, file ten separate appeal packets. MetroPlus uses OCR intake for appeals, and sending a massive PDF with ten different patients will trigger a HIPAA rejection and further delay your money.
