New York Medical Billing Laws Compulsory for Behavioral Health Providers
Behavioral health providers in New York must comply with state insurance laws, Medicaid billing regulations, mental health treatment requirements, patient financial protections, and federal healthcare laws. These requirements affect psychiatrists, psychologists, therapists, licensed mental health counselors, psychiatric nurse practitioners, outpatient mental health clinics, and substance use disorder (SUD) treatment facilities.
Below is a list of the major New York medical billing laws and regulations relevant to behavioral health medical billing.
1. New York State Medical Billing Laws
| Law or regulation | Key requirements for behavioral health billing |
|---|---|
| New York Prompt Pay Law — Insurance Law § 3224-a | Generally requires insurers to process payable electronic claims within 30 calendar days and paper claims within 45 calendar days. |
| New York Timely Filing Rules — Insurance Law § 3224-a | Generally requires providers to submit commercial insurance claims within 120 days and Medicaid managed care claims within 90 days, subject to applicable exceptions. |
| New York Mental Health Parity Requirements — Insurance Law §§ 3216, 3221 and 4303 | Require applicable health plans to provide mental health and SUD coverage consistent with New York's coverage and parity requirements. Providers must apply the correct patient cost-sharing and coverage rules. |
| New York Surprise Bill Law — Public Health Law § 24 and Financial Services Law Article 6 | Establishes disclosure and patient protections for covered out-of-network and surprise medical bills. |
| Fair Medical Debt Reporting Act — General Business Law and related amendments | Prohibits covered healthcare professionals from reporting medical debt to consumer reporting agencies and requires corresponding restrictions in collection contracts. |
| Hospital Financial Aid Law — Public Health Law § 2807-k(9-a) | Requires qualifying New York hospitals to provide financial assistance to eligible patients, including patients receiving hospital-based behavioral health care. |
| Insurance Law and Public Health Law Article 49 | Govern utilization review, medical necessity determinations and appeals for covered healthcare services, including behavioral health treatment. |
Billing implications: Providers should verify eligibility, coverage, copayments, deductibles, network participation and filing deadlines before submitting claims or collecting patient balances.
Official references: New York Department of Financial Services guidance on claim submission and prompt payment and mental health and substance use disorder coverage.
2. Behavioral Health-Specific Billing Regulations
| Regulation | Applicability and billing requirement |
|---|---|
| 14 NYCRR Part 599 | Applies to OMH-certified Mental Health Outpatient Treatment and Rehabilitative Services (MHOTRS) programs. Governs eligible services, treatment documentation, staffing and Medicaid billing requirements. |
| 14 NYCRR Part 596 | Governs telehealth services in OMH-licensed or designated programs, including documentation, service delivery and applicable telehealth billing requirements. |
| 14 NYCRR Part 822 | Applies to OASAS-authorized substance use disorder outpatient programs. Establishes treatment, recordkeeping and Medicaid reimbursement standards. |
| 14 NYCRR Part 841 | Establishes Medicaid requirements for addiction services, including covered services and reimbursement standards. |
| 14 NYCRR Part 830 | Establishes OASAS telepractice standards relevant to reimbursement for eligible SUD services. |
| Mental Hygiene Law Article 31 | Establishes licensing and operating requirements for mental health facilities under OMH jurisdiction. Proper authorization is necessary for the corresponding facility billing. |
| New York Medicaid Managed Care Behavioral Health Billing and Coding Rules | Establish service-specific coding, claim submission and reimbursement requirements for Medicaid managed care behavioral health programs. |
These regulations are especially important for outpatient mental health clinics, community behavioral health programs, addiction treatment facilities and other state-certified programs.
Important distinction: An independent psychiatrist or private psychotherapy practice does not automatically fall under every OMH or OASAS facility regulation. Requirements depend on the provider's license, certification, services and payer contracts.
Official references: OMH Part 599 regulations, OMH telehealth requirements and Medicaid behavioral health billing guidance.
3. New York Medicaid Billing and Compliance Laws
These rules apply to behavioral health providers enrolled in New York Medicaid, subject to each regulation's scope.
| Law or regulation | Billing compliance requirement |
|---|---|
| 18 NYCRR § 540.6 | Medicaid fee-for-service claims generally must be submitted within 90 days, with specified exceptions and resubmission rules. |
| 18 NYCRR § 540.7 | Requires accurate, itemized Medicaid billing and supporting records. Generally requires billing documentation to be retained for at least six years from payment, unless another rule requires longer retention. |
| 18 NYCRR § 504.3 | Requires enrolled Medicaid providers to maintain records supporting their entitlement to reimbursement and make them available for inspection. |
| Social Services Law § 363-d and 18 NYCRR Part 521 | Require designated Medicaid providers to establish and maintain effective compliance programs to prevent fraud, waste and abuse. |
| Social Services Law § 363-d(6) | Requires Medicaid providers to identify, report, explain and return overpayments, generally within 60 days of identification or the applicable cost-report deadline, whichever is later. |
| Medicaid Third-Party Liability Rules — 18 NYCRR § 540.6 | Require billing other liable insurers before Medicaid when applicable, because Medicaid is generally the payer of last resort. |
| New York Medicaid Managed Care Billing Guidance | Establishes program-specific codes, modifiers, reimbursement procedures and claim requirements for behavioral health services. |
These regulations are especially important for outpatient mental health clinics, community behavioral health programs, addiction treatment facilities and other state-certified programs.
An important distinction is that the Medicaid fee-for-service 90-day rule and Medicaid managed care timely filing rules must be checked separately. The applicable managed care plan's requirements and state protections control its claims.
Official references: Medicaid billing regulations and OMIG compliance requirements.
4. Federal Laws Applicable to New York Behavioral Health Billing

6. Most Important Laws for Behavioral Health Medical Billing Companies
For a New York psychiatry, psychology, psychotherapy or addiction treatment practice, these are the key compliance areas to prioritize:
- Insurance Law § 3224-a: Timely claim submission and insurer payment.
- New York mental health parity and insurance coverage laws: Proper application of behavioral health benefits and patient cost-sharing.
- 14 NYCRR Part 599: OMH outpatient clinic billing, when applicable.
- 14 NYCRR Parts 822 and 841: OASAS treatment and Medicaid reimbursement requirements, when applicable.
- 18 NYCRR §§ 540.6 and 540.7: Medicaid claim submission and billing documentation.
- Social Services Law § 363-d: Medicaid compliance and overpayment obligations.
- 42 CFR Part 2 and HIPAA: Confidentiality of mental health and substance use treatment records.
- New York Fair Medical Debt Reporting Act: Patient collection and medical debt reporting restrictions.
Key compliance point: Billing requirements differ between private behavioral health practices, OMH-licensed clinics, OASAS-certified treatment programs, hospital-based psychiatry departments and independent telehealth providers. A behavioral health billing company should determine the provider's regulatory category and payer mix before applying these laws.
These are the principal requirements, not an exhaustive legal inventory. For provider-specific compliance, current payer contracts, licensing rules and state guidance must also be reviewed.
Conclusion
Keeping up with New York's billing requirements can be challenging, especially when insurance policies, reimbursement rules, and state regulations continue to change. Even small billing mistakes can lead to denied claims, delayed payments, or unnecessary financial losses.
The best approach is to identify potential billing issues early, keep documentation accurate, and regularly check for regulatory updates. With the right billing processes and expert support, behavioral health providers can spend less time resolving claims and more time focusing on patient care.
