New York Commercial Mental Health Billing: 5 Easy Steps
New York commercial mental health billing is the work of getting behavioral health claims paid by insured private plans in New York. New York has its own mental health coverage law, known as Timothy’s Law, and the Department of Financial Services (DFS) has issued letters on how insurers must process psychiatrist visits. This guide explains what those rules say, what they do not say, and how to build a claim routine around them.
What New York commercial mental health billing starts with
Start with two questions for every patient: is the plan insured or self-funded, and who administers the behavioral health benefit? DFS letters are addressed to licensed insurers, so the plan type changes which rules apply. Run both checks during patient benefit verification and record the answers. Our insurance companies contact directory helps you reach the right payer line.
| Question | Why it matters | What to record |
|---|---|---|
| Insured or self-funded? | New York insurance letters address licensed insurers, Article 43 corporations and HMOs | Plan type and date asked |
| Who manages behavioral health? | The claims address and rules may differ from the medical plan | Administrator name and portal |
| Network status | Cost share and limits differ in and out of network | Status and effective date |
| Visit limits | Timothy’s Law sets a floor, and a plan may offer more | Number and period |

How New York commercial mental health billing differs by payer
Private payers
Each commercial plan sets its own contract, fee schedule, authorization rules and appeal windows, so one plan’s answer does not carry to another. Confirm network status for each clinician and ask the plan for the out-of-network deductible and coinsurance if you are outside the network. Our guides to in-network and out-of-network credentialing and coinsurance, copay and deductible explain the cost-share terms you will record.
Medicare and Medicaid
Medicare and Medicaid follow separate rules, and this guide covers neither in depth. For Medicare, Medicare.gov lists psychiatrists, clinical psychologists, clinical social workers, marriage and family therapists and mental health counselors among outpatient mental health providers. This post does not cover New York Medicaid, so use the state Medicaid provider manuals for those claims.
State rules
DFS Circular Letter No. 3 (2007) summarizes Timothy’s Law, which took effect January 1, 2007 and amended Insurance Law sections 3221 and 4303. It requires covered plans to provide at least 30 days of inpatient mental health treatment and at least 20 outpatient days per calendar year. It requires large-group coverage (over 50 employees) of biologically based mental illness and children’s serious emotional disturbances to be comparable to medical coverage, and requires small groups to be offered that coverage. The letter says these benefits cannot face extra utilization review, and that deductibles and coinsurance must match those for other benefits. Treat these numbers as a floor, and read the plan’s own limits.
For psychiatrists, DFS Circular Letter No. 1 (2023), dated February 10, 2023, tells insurers to accept and process psychiatrists’ claims that follow the current American Medical Association (AMA) CPT codes and guidelines, including evaluation and management (E/M) codes. It says office E/M level can rest on medical decision-making or total time. When a psychiatrist bills a psychotherapy add-on code the same day, the E/M level rests on medical decision-making alone. An earlier letter, Circular Letter No. 17 (2010), says insurers must accept E/M codes for mental disorders and may not limit accepted codes to those labeled psychiatric. Accepting a claim does not mean the plan must pay it.
Federal parity law also applies to many plans. The Department of Labor said on May 15, 2025 that it will not enforce the new provisions of the 2024 parity rule while litigation continues. The parity statute itself still applies.
How do you bill commercial insurance for mental health in New York?
For New York commercial mental health billing, verify the plan type and behavioral health administrator, bill the CPT code that matches the service, and keep the note that supports the time and medical decision-making. Psychiatrists should bill E/M plus the psychotherapy add-on under the current CPT rules, and cite DFS Circular Letter No. 1 (2023) if a plan reviews the E/M level by the wrong criteria.
A denial checklist for New York commercial mental health billing
- Read the remittance reason with our guide to CARC and RARC codes.
- Check network status, visit limits and authorization rules in the verification record.
- Compare the denial to the plan’s published criteria and your contract.
- For a psychiatrist E/M review, compare the plan’s stated criteria with Circular Letter No. 1 (2023).
- Appeal inside the window in your contract and keep the dates. A low clean claim rate shows which payer to fix first.
What to do Monday morning
Four small steps set up New York commercial mental health billing for the month.
- List your commercial payers and mark each as insured or self-funded where you know it.
- Add each plan’s behavioral health administrator and portal to one page.
- Pull last month’s behavioral health denials and sort them by reason.
- If a plan limits outpatient visits, ask whether the limit is the plan’s own or the Timothy’s Law minimum.
The short version: New York commercial mental health billing
New York commercial mental health billing depends on plan type, the behavioral health administrator and the plan’s own limits. Timothy’s Law sets minimums for covered plans, and DFS letters confirm that insurers must process psychiatrist E/M claims under current CPT rules. Verify, code to the note and appeal inside the contract window.

FAQ
What is Timothy’s Law?
It is New York’s mental health coverage law, effective January 1, 2007, which amended Insurance Law sections 3221 and 4303. DFS Circular Letter No. 3 (2007) says it requires covered plans to provide at least 30 inpatient days and at least 20 outpatient days of mental health treatment per calendar year, with parity for certain conditions in large groups.
Does New York require insurers to accept psychiatrist E/M claims?
Yes. DFS Circular Letter No. 1 (2023) tells insurers to accept and begin processing psychiatrists’ claims that follow current CPT codes and guidelines, including E/M codes. Accepting a claim does not require the plan to pay it.
How is the E/M level chosen when I bill a psychotherapy add-on code?
DFS Circular Letter No. 1 (2023) says that when a psychiatrist bills psychotherapy as an add-on code on the same day as an E/M service, the E/M code is selected on medical decision-making alone.
Do these New York rules apply to every plan my patients have?
Not necessarily. The DFS letters address licensed insurers, Article 43 corporations and HMOs. Ask whether a plan is insured or self-funded, and ask counsel how state rules apply to a self-funded plan.
