MetroPlusHealth, the NYC Health + Hospitals plan, carries the NY Medicaid ABA carve-in with two plan-specific wrinkles worth designing intake around. First, the mechanics are old-school: ABA authorization requests and clinical information go to MetroPlus CSS by email or fax, not a slick portal workflow. Second — and unique among the plans we profile — MetroPlus requires the autism diagnosis to be authenticated and re-validated annually by the member's treatment team, a stricter cadence than the state's 2-year referral rule, and it holds that LBAs don't meet the practitioner level to validate the diagnosis themselves.
MetroPlus states that LBAs do not meet the practitioner level to authenticate or validate an autism diagnosis — so ABA providers must coordinate with the member's treatment team (physician, psychologist, or other qualified NYS-licensed clinician) to have the diagnosis authenticated and validated annually. That's a materially tighter clock than the state's 2-year referral: for every MetroPlus family, intake should diary an annual diagnosis-revalidation task with the diagnosing or treating clinician, or reauthorization becomes an avoidable scramble. The underlying diagnostic requirement is a comprehensive autism evaluation by a NYS-licensed clinician accompanying or preceding the diagnosis.[1]
Per the plan's 2023 benefit notice, authorization requests and supporting clinical information are submitted to MetroPlus CSS by email or fax — build a submission template and a delivery-confirmation habit, since email/fax workflows lack a portal's status visibility. Assessment-PA specifics, authorization periods, hour caps, and rates aren't published in the materials we could verify; confirm current requirements with CSS or via the metroplus.org provider portal per case. The footprint is NYC-only, and the clinical baseline is the state's: under 21, ASD/Rett, practitioner referral.[1][3]
The questions that decide whether a family can start with MetroPlusHealth (NY Medicaid), and what they have to bring. Each maps onto something intake should ask on the first call.
Follows the New York Medicaid rule: ABA is covered for members “under 21 years of age with a diagnosis of Autism Spectrum Disorder (ASD) as defined by… (DSM-5) and/or Rett Syndrome.” No minimum age and no adult pathway — the 21st birthday is a hard cliff. MetroPlus publishes no age rule of its own; its footprint, not its age rule, is the plan-specific limit — New York City only.[3][1]
Stricter than the state, and this is the fact to design intake around. Where New York Medicaid runs a 2-year referral clock, MetroPlus requires the autism diagnosis to be “authenticated and validated annually” by the member’s treatment team. Diary a yearly diagnosis-revalidation task with the diagnosing or treating clinician for every MetroPlus family, or reauthorization becomes an avoidable scramble.[1][3]
Follows the New York Medicaid referral rule, plus a MetroPlus exclusion that matters: LBAs “do not meet the practitioner level to authenticate or validate an autism diagnosis,” so ABA providers must coordinate with the member’s treatment team — physician, psychologist, or another qualified NYS-licensed clinician — to have the diagnosis authenticated and validated. The underlying requirement is a comprehensive autism evaluation by a NYS-licensed clinician accompanying or preceding the diagnosis.[1][3]
No instrument is named. MetroPlus requires “a comprehensive autism evaluation by a NYS-licensed clinician” behind the diagnosis but does not specify which instruments must sit inside it; the state baseline requires only the DSM-5 Diagnostic Checklist with the referral and the standardized assessment used, identified as appropriate.[1][3]
Follows the New York Medicaid rule: the member “must be referred for ABA services by a NYS-licensed and NYS Medicaid-enrolled physician, psychologist, psychiatric nurse practitioner, pediatric nurse practitioner, or physician assistant,” the referral is “valid for no more than two years,” and it must carry age, the ASD/Rett diagnosis, date of initial diagnosis, co-morbid diagnoses, symptom severity level, a statement the patient needs ABA, and the DSM-5 Diagnostic Checklist. MetroPlus’s own mechanics are old-school: authorization requests and supporting clinical information go to MetroPlus CSS by email or fax rather than through a portal workflow, so build a submission template and a delivery-confirmation habit. Assessment-PA specifics and authorization periods are not published.[3][1]
Ask the plan: MetroPlus CSS, or the metroplus.org provider portal, for assessment-PA specifics and authorization periods.
MetroPlusHealth’s June 2026 manual tightened every Medicaid clock: a standard prior authorization is decided “within three (3) business days of the receipt of all necessary information, but no later than seven (7) days after the request is received”; a fast-track (urgent) request “within seventy-two (72) hours from the date that the request is received”; a continuing-care (concurrent) request within one business day of all necessary information, again no later than 7 days (72 hours if fast-track). Extensions shrank too: timeframes “may be extended seven (7) calendar days” at the member’s or provider’s request or when the plan needs information (the March 2025 manual allowed 14). ABA requests go to metroplusaba@metroplus.org or fax 212-908-5182. No ABA reauth lead time is published for Medicaid.[4][2]
MetroPlusHealth’s June 2026 manual publishes no coordination-of-benefits procedure of its own (its only primary-insurer language covers no-fault and workers’ compensation denials), so the state rule governs. Medicaid is “the payer of last resort” and “Providers must bill all applicable insurance sources before submitting claims to Medicaid. Payment from those sources must be received before submitting a Medicaid claim”; under the state contract, when other coverage is known the plan must “alert the provider and ask them to bill the TPHI that should be primary to the Plan.” In practice: bill the commercial plan first, then MetroPlus with the primary’s EOB. Whether MetroPlus still requires its own ABA authorization when it is secondary is not published — ask Provider Services (800-303-9629).[5][6][4]
Not published. MetroPlus’s 2023 ABA benefit notice covers the submission channel and the annual diagnosis-validation rule and says nothing about which ABA codes may be delivered remotely; the state manual answers telehealth only for supervision.[1][3]
Ask the plan: MetroPlus CSS or the metroplus.org provider authorization page — confirm telehealth code eligibility and POS in writing before scheduling remote sessions.
Coverage decides whether MetroPlusHealth (NY Medicaid) pays. These decide whether the claim survives: how sessions must be staffed and supervised, what may be billed concurrently, the per-day ceilings, who signs the note, where the service is payable, and whose NPI the claim goes out under.
Follows the New York Medicaid rule, which the state applies to FFS and managed care alike: “an LBA can supervise no more than six CBAAs/unlicensed individuals at a time,” “LBAs are required to supervise unlicensed individuals for a minimum of five percent of the hours the unlicensed individual spends providing behavior analysis services each calendar month,” and “supervision must include at least two face-to-face, real-time contacts per month” with the LBA observing service delivery in at least one. Supervision may run over synchronous audio-and-video where on-site is impractical. 97155 counts toward the 5% “only when the LBA joins the patient and the unlicensed individual during a treatment session to direct the unlicensed individual/technician in implementing a new or modified treatment protocol.” CBAAs need direct supervision, and the supervisor “should assess each patient’s/client’s progress at least every 6 months… and review and sign treatment notes and reports prepared by the CBAA supervisee.” MetroPlus publishes no supervision ratio of its own; its plan-specific credential rule runs in the other direction, holding that LBAs do not meet the practitioner level to authenticate or validate the autism diagnosis.[3][1]
Follows the New York Medicaid rule: the LBA supervisor must “review and sign treatment notes and reports prepared by the CBAA supervisee,” and documentation of supervision itself “should be recorded in the patient file.” Clinical documentation must carry the treatment plan with assessment and goals, the goal data, total hours of service per week by who delivered them, and the location(s) of services. Records are kept “for a minimum of six years and, for minors, until the patient turns 22 years of age.” MetroPlus publishes no additional session-note signature rule; its one documentation-cadence rule is the annual diagnosis authentication by the treatment team.[3][1]
Follows the New York Medicaid rule: “LBAs and CBAAs may work in any legally authorized setting. Examples of such settings include private practice, settings where patients/clients reside full-time or part-time, clinics, hospitals, residences, and community settings” — but “NYS Medicaid does not reimburse for ABA services in a school setting.” The treatment plan must record the location(s) of services. No MetroPlus-specific setting rule was located; the footprint is the plan-specific constraint — New York City only.[3]
Ask the plan: MetroPlus CSS for any plan-specific setting restriction.
Not published. The 2023 benefit notice is a process document, not a reimbursement policy, and the state manual is silent on 97153 with 97155.[1][3]
Ask the plan: MetroPlus CSS or provider services via the metroplus.org provider authorization page.
Not published — MetroPlus states no authorization periods, unit ceilings or hour caps in the materials that could be verified. Treat the authorized units as the ceiling and get the authorization period in writing with each approval, since the email/fax workflow gives no portal status visibility.[1][2]
Ask the plan: MetroPlus CSS or the metroplus.org provider authorization page — confirm authorization period, unit limits and rates per case.
Not published. At the fee-for-service layer New York is explicit: LBAs bill “using the LBA’s National Provider Identification (NPI) number for the ‘Billing’ provider and/or ‘Supervising’ provider,” with “the NPI number of the CBAA that provided the ABA service… reported as the ‘Rendering’ provider on each claim”; for unlicensed aides and LBA limited-permit holders the supervising LBA’s NPI fills all three roles. CBAAs cannot bill directly and enroll as OPRA providers. MetroPlus states no managed-care claim convention of its own in the materials that could be verified, and the state manual directs MMC providers to their plan for billing guidance.[3][1]
Ask the plan: MetroPlus CSS or provider services — confirm the rendering/supervising NPI convention before billing CBAA- or technician-delivered units.
Yes — it carries the NY Medicaid ABA carve-in for NYC members under 21 with ASD/Rett, with authorization requests and clinical information submitted to MetroPlus CSS by email or fax.
Annually — MetroPlus requires the diagnosis be authenticated and re-validated every year by the member's treatment team, and holds that LBAs don't meet the practitioner level to do it. That's stricter than the state's 2-year referral rule.
No — it's the NYC Health + Hospitals plan, with a New York City-only footprint.
