Neurology Credentialing in New York: A Complete Guide for Practice Owners (2026)

Neurology credentialing in New York carries the same baseline rules as any other specialty, but the specialty adds a few wrinkles that don’t show up in a standard payer enrollment checklist: diagnostic testing that sometimes needs its own enrollment separate from the physician, high-cost injectables with their own prior authorization and drug-sourcing rules, and hospital-based stroke work that’s tied to a state designation program most practices never look at until a hospital asks them to.

Here’s what actually matters.

The rules that apply no matter which payer

New York Public Health Law 4406-d requires HMOs and insurers to complete review of a credentialing application within 90 days of receipt. For a newly licensed physician, or one who’s relocated to New York and is joining a practice where other physicians are already in-network, silence past that window triggers automatic “provisional credentialing,” meaning the physician is treated as in-network while the file is still open. Keep a dated record of every complete submission so you can invoke this if a plan goes quiet.

Separately, any physician who might see a Medicaid managed care patient, through EmblemHealth’s Medicaid line, a UnitedHealthcare Community Plan, or others, has to enroll directly with NYS Medicaid through eMedNY, even if they never bill Medicaid fee-for-service. This is a distinct application from MCO credentialing (the Ordering/Prescribing/Referring/Attending, or OPRA, enrollment), and plans now deny claims from providers who are in-network but not separately enrolled. This trips up new neurology hires constantly, especially at practices that see a lot of Medicaid managed care referrals for headache, seizure, or stroke follow-up care.

Payer by payer

UnitedHealthcare / Oxford. Oxford’s network only covers a defined set of downstate counties (the five boroughs, Nassau, Suffolk, Westchester, Rockland, Putnam, Dutchess, Orange, Ulster, and Sullivan) plus New Jersey and Connecticut. Upstate practices are credentialed under standard UnitedHealthcare commercial contracts instead. Separately, if your practice administers Botox or another neurotoxin for chronic migraine or spasticity, UHC is one of the payers that requires the drug to come through a third-party specialty pharmacy rather than letting the practice buy and bill from its own stock. That’s a real revenue difference (the practice loses the margin between acquisition cost and reimbursement) and it means setting up a specialty pharmacy relationship before you start treating UHC patients with injectables, not after the first denied claim.

Empire BlueCross BlueShield. Empire handles most provider transactions through Availity rather than a proprietary portal. For neurology specifically, confirm whether prior authorization for advanced neuroimaging (MRI, MRA) and neurophysiologic testing is managed by Empire directly or by a separate radiology or specialty benefit manager, since that varies by product line and changes periodically.

Aetna. CAQH-based, with most transactional work also through Availity. Aetna’s Botox precertification form specifically asks whether the drug is prescribed by, or in consultation with, a neurologist or another qualifying specialist, and requires documentation of at least two failed classes of preventive medication. Have that treatment history organized before submitting, since incomplete trials are the most common reason these get kicked back.

EmblemHealth. Still the largest legacy HMO across the five boroughs. Because Emblem’s commercial book overlaps heavily with its Medicaid managed care line, this is the payer where the eMedNY enrollment gap shows up most often. Confirm eMedNY status before a new hire’s start date.

Cigna. A smaller commercial footprint in New York, concentrated more in NYC and the lower Hudson Valley. Standard CAQH process.

MVP Health Care. The dominant commercial and Medicaid managed care plan across most of Upstate New York, including Albany, Utica, Syracuse, Rochester, and the North Country. MVP requires a CAQH ProView application re-attested within the last 90 days and expanded its use of CAQH’s data validation tools in mid-2025, so a stale profile gets flagged faster than it used to. Minimum malpractice coverage is $1 million per occurrence and $3 million aggregate.

The parts unique to neurology

EMG, NCS, and EEG testing. If your practice performs these tests in-house, on your own established patients, that’s typically treated as in-office ancillary testing and doesn’t require anything beyond standard physician credentialing. But if the practice starts performing these tests for patients referred in by outside physicians as a stand-alone diagnostic service, Medicare and most commercial payers start treating the practice as an Independent Diagnostic Testing Facility. That means a separate CMS-855B enrollment, a mandatory site visit, a listed supervising physician, and documented technician credentials (for example, ABRET registration for EEG techs). This distinction gets missed constantly by growing neurodiagnostic practices, and it’s worth reviewing before you start actively marketing testing services to other referring physicians.

Stroke call coverage. New York designates hospitals as Primary, Thrombectomy Capable, or Comprehensive Stroke Centers under 10 NYCRR 405.34, and EMS protocols preferentially route suspected stroke patients to designated facilities. A Comprehensive Stroke Center must have a neurologist available, in person or by telemedicine, within 15 minutes of a consult request, and the hospital’s Stroke Medical Director has to be board certified in a qualifying specialty and log continuing education hours annually. If you take stroke call at a hospital pursuing or maintaining this designation, your board certification, response times, and documentation feed directly into that hospital’s designation renewal. It’s worth confirming with the hospital’s stroke coordinator that your credentialing file has what they need well before a survey.

A practical starting sequence

1. Get CAQH ProView current for every physician, attested within the last 90 days.
2. Submit commercial applications to UnitedHealthcare, Empire, Aetna, EmblemHealth, Cigna, and MVP in parallel.
3. File eMedNY OPRA enrollment for every physician who might see a Medicaid managed care patient.
4. If the practice performs EMG, NCS, or EEG testing for outside referrals, evaluate whether you need a separate IDTF enrollment before that volume grows.
5. If administering Botox or another neurotoxin, confirm buy-and-bill versus specialty pharmacy requirements payer by payer, and build a tracking system for authorized units and treatment windows.
6. If you take hospital stroke call, coordinate with the stroke program early so your privileging and board certification documentation lines up with the hospital’s DOH designation requirements.
