To enroll an In-state Hospital Facility in New York State Medicaid, the facility must be certified by either the Office of Health Systems Management (OHSM), the Office of Alcoholism & Substance Abuse Services (OASAS) or the Office of Mental Health (OMH), depending on the type of services provided. The phone numbers for these agencies can be found in the blue government section of the phone book. Once the licensing documentation is reviewed, the facility’s representative will be contacted and an enrollment package will be mailed to the address provided.

To begin the rate process for OHSM certified providers, contact the Bureau of Primary and Acute Care Reimbursement at (518) 474-3267. To begin the rate process for OASAS certified providers, contact OASAS at (518) 485-2250. To begin the rate process for OMH certified providers, contact OMH at (800) 597-8481.

Please Note: Existing providers have the option of billing new programs or services with an NPI already enrolled with the NY State Medicaid Program or an NPI unknown to NYS Medicaid. To report an unknown NPI, an enrollment application will be sent to you to complete and return to Medicaid's fiscal agent, Computer Sciences Corportion (CSC). Adding a new service or program to an enrolled NPI may require completion of other enrollment documents. Please contact the Rate Based Provider Bureau at (518) 474-3575, option 4 or (800) 342-3005, option 4 if you have any questions regarding these NPI options.
