Autism Care Demonstration: Guidelines on Tax Identification Numbers and Reimbursement

Wednesday, December 6, 2023

For your Autism Care Demonstration (ACD)-related reimbursements to process correctly, it is important providers keep Health Net Federal Services, LLC (HNFS) informed of Tax Identification Numbers (TIN) changes. The TIN listed in an ACD authorization must be current and match the TIN submitted on the associated claims. Incorrect or non-matching TINs require HNFS to rekey authorizations and can lead to denied claims and delayed reimbursement.

Non-Matching TINs 

If HNFS authorizes applied behavior analysis services under a group TIN, but the related claim lists a different group TIN, we will deny the claim for not having an associated authorization. Make sure to send HNFS any changes made to TINs as soon as possible. This will allow us time to authorize services under the new TIN (or update active authorizations before you submit respective claims). You can verify which TIN shows on current authorizations when using our Authorization Status tool (login required).

Fax or Email HNFS TIN Changes or Additions 

ABA provider groups must submit a completed W-9 containing an updated TIN along with a letter on company letterhead to HNFS.

Please allow HNFS up to 60 days to process provider updates. Providers can email ACDNetwork@hnfs.com after 21 days to check processing status.
