CHDP Phase 3 HIPAA Code Conversion: School-Based Services Crosswalk

July 25, 2018

The Department of Health Care Services (DHCS) is initiating Phase 3 of the Child Health and Disability Prevention (CHDP) claim form transition and code conversion. To comply with HIPAA national standards for health care electronic transactions and code sets, school-based services will transition to national standards in the fourth quarter of 2018.

CHDP school-based providers will bill services directly to Medi-Cal in accordance with HIPAA national standards. Services will be billed with CPT-4 national codes on the UB-04 claim form or electronic equivalent. Services billed on the incorrect claim form for the date of service will be denied.

In addition to meeting HIPAA standards, this transition adapts CHDP billing to the American Academy of Pediatrics (AAP) February 2017 Bright Futures periodicity schedule and enhanced Bright Futures services.

Code Conversion Table
The full code conversion is available in the CHDP Code Conversion Table.

CHDP Program
The CHDP program reimburses for outpatient preventive health services for eligible children and youth. In California, the CHDP program provides the early and periodic screening component of the federally mandated Early and Periodic Screening, Diagnosis, and Treatment (EPSDT) benefit for Medi-Cal recipients.

Billing and Reporting
It is recommended that providers plan to bill electronically. Providers who are not able to bill electronically and do not have a supply of national claim forms should order them. Providers should work with a credible vendor and purchase forms with “drop-out” ink that meet Centers for Medicare & Medicaid (CMS) standards.


To bill, CHDP providers must have an active Medi-Cal NPI.

Information submitted on UB-04 claim forms does not need to be forwarded to county CHDP offices, as was required with the CHDP PM 160.

For providers who are not actively billing on the UB-04 claim form, a claim completion, computer-based training (CBT) course is available through the Medi-Cal Learning Portal (MLP).

CHDP/EPSDT services billed with national codes on the UB-04 or electronic equivalent are reimbursable at Medi-Cal rates. Reimbursement will be made on providers’ Medi-Cal warrant for claims processed with dates of service on or after the transition date.
