  6. Step 6

Step 1 (Required)   Receive an ETIN

As a result of filling out the ETIN Certification Statement for New Providers, you will receive notice in the mail of the ETIN that has been generated for you.

If you wish to affiliate with an already existing ETIN, you may submit a Certification Statement for Currently Existing ETINs here. Wait for confirmation of set up with the second ETIN before submitting claims with it.

Step 2 (Required)   Learn Medicaid Billing Policies and Procedures

Before rendering service to a client, providers need to become familiar with the policies and procedures of the Medicaid Program.

Step 3 (Optional)   Sign-up for the Medicaid Update

NYS Medicaid publishes a monthly newsletter known as the Medicaid Update. The newsletter is available on the New York State Department of Health website. The Medicaid Update highlights changes to Medicaid policy and procedures and should be reviewed by providers each month.

Current and previous issues of the NYS Medicaid Update may be found at the NYSDOH website http://www.health.ny.gov/

Step 4 (Required)   Determine how you will submit claims to eMedNY

Providers are given several options for submitting claims to eMedNY

Option 1: HIPAA Compliant Claim Formats Submitted Directly to eMedNY

HIPAA-compliant 837 Professional (837P), Institutional (837I), 837 Dental (837D), NCPDP (pharmacy) and formats directly to eMedNY or through a Service Bureau. There are Companion Documents that describe how the electronic transaction must be formatted based on HIPAA requirements located under eMedNYHIPAASupport tab, then choose 5010/D.0 Companion Guides (CGs) here: https://www.emedny.org/HIPAA/5010/transactions/index.aspx

Option 2: Medicaid's Electronic Provider Assisted Claim Entry System (ePACES) web-based application

ePACES is an internet-based program that will allow an enrolled provider to submit claims as well as many other types of transactions in a HIPAA-compliant format. ePACES supports the following types of transactions: *Real-time means that the claims are processed instantaneously and the provider can view the status of a real-time claim within seconds. There is no need to wait for a remittance statement to be mailed to find out about the status of submitted claims.
**The status of claims (paid, pended or denied) submitted via the ePACES batch feature is generally available within 24 hours.


To enroll in ePACES: All you need to enroll in ePACES is a NYS Medicaid Provider ID number, an ETIN, and an internet address. Contact the eMedNY Call Center at 1-800-343-9000 to begin the enrollment process.

Option 3 Paper Claim Forms

For Providers who absolutely have no choice but to submit paper claims, there is information available regarding paper claims, located by clicking on Information, then eMedNY Paper Forms.

(Note: Once a provider is fully enrolled, a supply of paper claim forms will be mailed to the Provider.)

Step 5 (Optional)   Setting up Remittance Advice Receipt and Payment Options

The processing of most Medicaid transactions is performed by the eMedNY fiscal agent for the NYS Medicaid Program. eMedNY processes transactions 24 hours a day, 7 days a week and issues checks and remittance statements weekly, for processed claims.

Remittance Advices are generated every week for claims submitted from Thursday to Wednesday prior, and are available in multiple formats.

ENQUIRIES: Questions should be directed to the eMedNY Call Center at 1-800-343-9000. Before submitting claims, providers may also phone the Call Center to request training from a eMedNY Regional Representative.

Payments will be sent to the bank account used for Electronic Funds Transfer unless the form sent with your enrollment packet was rejected, in which case you will receive paper checks. See Electronic Funds Transfer (EFT) Authorization Form - #701101 for more information.

Step 6 (Optional)   Submitting Claims

Multiple steps are required to submit claims to eMedNY.

a) Verify Client Eligibility via MEVS or ePACES

Providers must verify the eligibility of the client via the Medicaid Eligibility Verification System (MEVS) before rendering service.

The MEVS manual gives detailed instructions for the available methods for verifying eligibility and the meaning of messages returned by MEVS. MEVS verifies a client's eligibility for any current or past date of service and gives information about their enrollment in Medicaid Managed Care plans, Medicare or other insurance coverage.

If other coverage exists for the client, the provider will need to bill the other insurance first as Medicaid is the Payer of Last Resort. The MEVS Manual is found under Provider Manuals, in MEVS and Supplemental Documentation.Click Here for the MEVS Manual


b) Submit Prior Approval as Required

Certain services require prior approval (PA) by the appropriate NY State or county office before a claim can be submitted.

Please review the provider manual specific to your provider type to obtain information regarding PA requirements. If PA is required, they may be submitted by:

Rosters showing the outcome of your PA requests will be mailed to you unless you sign up to receive these rosters electronically. To sign up for receiving PA rosters electronically in PDF format, first sign up for ePACES, then complete the Electronic Prior Approval Request Form

The Prior Approval Roster Request Form is available at emedny.org, under Information, eMedNY Paper Forms, Prior Authorization Forms.
