Cardiology Billing Services in New York

Cardiology services for New York Medicaid patients run through Medicaid Managed Care MCOs: Healthfirst, Fidelis Care (Centene), MetroPlus Health Plan, EmblemHealth, Affinity Health Plan, Molina Healthcare, UnitedHealthcare Community Plan, and Anthem (Amerigroup). Each plan has its own cardiology network and prior auth pathway. For procedures like 93458 (left heart catheterization), 92928 (PCI with stent), nuclear cardiology codes (78451, 78452), and advanced imaging (cardiac MRI 75557), prior authorization is required across all NYMMC MCOs. HARP (Health and Recovery Plan) covers individuals with serious mental illness or substance use disorder — relevant for cardiology when SMI/SUD patients need procedural cardiac care. Managed Long Term Care (MLTC) covers complex elderly cardiac patients. New York Medicaid timely filing is 365 days for FFS, with each MCO setting its own filing window. We build per-MCO cardiology workflows including portal-based auth submission, peer-to-peer scheduling for adverse determinations, and per-plan documentation expectations referenced to ACC/AHA appropriate use criteria.

New York's commercial cardiology payer landscape splits geographically. Empire Blue Cross Blue Shield (Anthem) is dominant in NYC, Long Island, and the lower Hudson Valley. Excellus BCBS covers Central and Western New York (Rochester, Syracuse, Buffalo, the Southern Tier, and the North Country). UnitedHealthcare, Aetna, Cigna, and Oscar Health cover both regions. Empire and Excellus both delegate advanced cardiology imaging prior auth to Carelon Medical Benefits Management (formerly AIM) — the same workflow for stress echocardiography (93350/93351 — CMS's NCCI Policy Manual, Chapter 11, names those as the stress echocardiography codes), nuclear cardiology (78451, 78452), cardiac CT angiography (75574), and cardiac MRI (75557, 75561). Each plan applies ACC/AHA appropriate use criteria. Peer-to-peer review is available within 14 days of an adverse determination. UnitedHealthcare uses Optum and Optum-affiliated programs for advanced cardiology auth. Aetna uses delegated arrangements. NYC and Long Island cardiology is shaped by NYU Langone, Mount Sinai (the Mount Sinai Heart program), NewYork-Presbyterian (Columbia and Cornell campuses), Northwell Health (the Sandra Atlas Bass Heart Hospital), and Maimonides — system contracting affects fee schedules and authorization workflows.

New York is a No-Fault auto insurance state, which creates a separate billing rail for medical care provided to motor vehicle accident patients. For cardiology, No-Fault becomes relevant when an auto accident triggers cardiac evaluation (post-trauma chest pain workup, ECG, stress testing for occult cardiac contusion or pre-existing condition exacerbation, or troponin elevation evaluation). No-Fault claims are billed under New York Insurance Department fee schedules (different from commercial or Medicare rates) and submitted via NF-3 forms or electronic equivalents to the patient's auto insurer. Strict timelines apply: notification of treatment to the auto insurer typically within 30 days of the first treatment date, ongoing treatment narratives required at specified intervals, and verification requests must be answered. The auto insurer's medical reviewer (a Designated Medical Examiner under No-Fault) may schedule an independent medical examination (IME) that affects continued benefit authorization. We manage No-Fault cardiology billing as a distinct workflow — separate fee schedules, separate document filing, and separate appeals process when the auto insurer denies medical necessity.

New York Insurance Law Section 3224-a sets the clock, and the first thing to establish is whether it reaches the plan at all. By its own opening it governs health care claims under contracts issued pursuant to Article 32 and Articles 42, 43 and 47 of the Insurance Law and Article 44 of the Public Health Law, and it binds insurers and the corporations and organizations licensed or certified under those articles. A self-funded employer plan paying its own claims is not one of them, and neither is Medicare or a Medicare Advantage plan. On a downstate cardiology panel carrying real MA and self-funded volume, that plan-type check comes before the prompt-pay letter.

Where the section does apply, subsection (a) requires payment within thirty days of a claim transmitted electronically and forty-five days of one submitted by other means, such as paper or facsimile. Two exceptions sit in the same sentence: where the obligation to pay is not reasonably clear, and where there is a reasonable basis, supported by specific information available for review by the superintendent, that the claim was submitted fraudulently. Note what the trigger is not — the statute does not condition the clock on a "clean claim." Where the obligation is unclear because of a good-faith dispute, subsection (b) requires the payer to pay any undisputed portion and, within thirty calendar days, to say in writing whether the claim is denied or partially approved, which payment it is not obligated to make and why, and to request all additional information it needs; once that information or an appeal arrives the subsection (a) clock runs again, and any additional payment found due must be made within fifteen days of the determination.

The interest rule is the one most often misquoted, including on billing-vendor pages. Subsection (c)(1) sets interest on an overdue amount at the greater of twelve percent per annum or the rate the New York Commissioner of Taxation and Finance sets for corporate taxes under paragraph one of subsection (e) of Section 1096 of the Tax Law, computed from the date the payment was required to be made. There is no federal funds rate anywhere in the section. Interest below two dollars need not be paid, which is why interest is worth pursuing on cath lab and device claims and not worth the letter on a tracing.

Two New York deadlines run the other way, against the practice, and both belong on a cardiology A/R calendar. Subsection (g)(1) makes a claim valid and enforceable only if it is initially submitted within one hundred twenty days after the date of service, unless the contract gives the provider more favourable terms; Medicaid and Child Health Plus contracts may set a different period, but not less than ninety days. Subsection (h) then lets a participating provider ask for reconsideration of a claim denied solely as untimely, where the lapse followed an unusual occurrence and the provider has a pattern of filing on time — but the payer may reduce that claim by up to twenty-five percent, and the subsection does not apply at all to a claim submitted three hundred sixty-five days after the date of service, which may be denied in full.

We track every claim against the thirty-day clock, flag stalled payments at day twenty-five, and file DFS prompt-pay complaints when payers default. There is a structural reason to file rather than to phone. Subsection (c)(2) shields a payer from the civil penalty where the superintendent finds violations through the superintendent's own investigation, examination, audit or inquiry and the payer processed at least ninety-eight percent of a calendar year's claims in compliance — but that paragraph "shall not apply to violations of this section determined by the superintendent resulting from individual complaints submitted to the superintendent by health care providers or policyholders." A documented provider complaint sits outside the safe harbour; a phone call does not. (Statute text read at the New York State Senate's published consolidated laws, the revision in effect 19 September 2025, on 17 September 2026.)

93458 (left heart cath with ventriculography) is the highest-prior-auth-rate code in NY commercial cardiology — Empire, UHC, Aetna, and Excellus all require Carelon-mediated approval with documented appropriate use. 93306 (complete TTE with Doppler) needs medical necessity documentation, especially for follow-up echos within 12 months of a prior. 93015 is the global cardiovascular stress test code, and it is not the code you split with -26 and -TC. The stress test family runs 93015-93018 — the range CMS's NCCI Policy Manual, Chapter 11, revision date 1 January 2025, calls the traditional exercise stress test — and which code in that range is correct turns on what the practice actually furnished in that setting. Settle it against the payer's fee schedule for that place of service before the first claim goes out, not with a component modifier on the global code afterwards. 93000 (ECG with interpretation and report) has a narrower bundling rule than it is usually given: CMS's NCCI Policy Manual, Chapter 11, states that a cardiovascular stress test includes the ECG strips at 93000-93010 and that those "shall not be reported separately," and likewise bars them where they relate to delivery of an anesthetic agent. Code against that edit rather than against a blanket assumption that a tracing disappears into any same-day E/M. 93295 (remote ICD interrogation) has tightened documentation requirements across NY commercial plans. 92928 (PCI with stent) is reported with affected vessel modifiers (-LD, -RC, -LC, -LM). 93798 (cardiac rehab with monitoring) requires per-session documentation, and the Medicare limit is worth knowing precisely because commercial plans are often benchmarked against it: 42 CFR 410.49 caps cardiac rehabilitation at two 1-hour sessions per day, up to 36 sessions over up to 36 weeks, with an option for a further 36 sessions over an extended period if the Medicare Administrative Contractor approves (intensive cardiac rehabilitation runs to 72 sessions, up to 6 a day, over up to 18 weeks). Regulation text read on 17 September 2026. Empire BCBS and the NYMMC MCOs set their own limits. 78452 (nuclear myocardial perfusion imaging, multiple studies) needs Carelon prior auth and ACC/AHA AUC scoring.

Cardiology billing in NYC, Long Island, and downstate is shaped by the dominant health systems. NYU Langone, Mount Sinai (with the Mount Sinai Heart program at Icahn School of Medicine), NewYork-Presbyterian (Columbia campus and Weill Cornell campus), Northwell Health (the Sandra Atlas Bass Heart Hospital and the Lenox Hill Heart and Vascular Institute), and Maimonides Medical Center (Brooklyn) drive cardiology contracting in their respective referral networks. Practices employed by or affiliated with these systems carry system-level commercial contracts with Empire, UHC, Aetna, and others — typically with higher fee schedules than independent practices but with system-controlled scheduling, EHR (Epic in most cases), and billing workflows. Independent cardiology practices contract directly with payers and have more flexibility but typically lower commercial fee schedules. Upstate cardiology is shaped by Rochester Regional Health and University of Rochester Medical Center (Rochester), Kaleida Health and Catholic Health (Buffalo), SUNY Upstate Medical University (Syracuse), and Albany Medical Center.
