HIPAA: Code Conversions

The Health Insurance Portability and Accountability Act (HIPAA) mandates the standardization of internal (administrative) code sets and the use of standard service/procedure code sets for transactions. The Medi-Cal program is using a phased approach to convert its interim (local) codes to national values.

The links below provide additional information about Medi-Cal code conversions. Providers and submitters are encouraged to check this page periodically for new information.

CHDP

The Child Health and Disability Prevention (CHDP) program code conversion transitions providers billing CHDP Medi-Cal Early and Periodic Screening, Diagnostic and Treatment (EPSDT) services using local codes to billing these services with HIPAA-compliant code sets. Transitioning from billing services with local codes on the Confidential Screening/Billing Report (PM 160) to billing national codes on the CMS-1500 or UB-04 claims, or electronic equivalents, is based on a date-of-service cutover.

Refer to the CHDP Provider Manual and Bulletins page for more information.

EPSDT Services: Home Health  

A forthcoming code conversion will establish a method to distinguish Early and Periodic Screening, Diagnosis and Treatment (EPSDT) services for Home Health services. This code conversion will replace non-HIPAA-compliant local codes with national HIPAA-compliant HCPCS procedure codes. National codes identified in combination with an EP modifier will allow for the distinction from adults and preserve the current rate allotted for children. Children's Home Health services covered by Medi-Cal under EPSDT regulations are uniquely identifiable for the purposes of preserving benefits and rates.

FQHC/RHC/IHS-MOA

Rural Health Clinics (RHCs) extend Medicare and Medi-Cal benefits and provide health care services in rural areas of California. Specifically trained primary care practitioners administer the health care services needed by the community when access to traditional physician care is difficult.

Federally Qualified Health Centers (FQHCs) were added as a Medi-Cal provider type in response to the Federal Omnibus Budget Reconciliation Act (OBRA) of 1989. FQHCs provide health care services in rural and urban areas of California.

California's Indian health care delivery system consists of a network of Indian health programs delivering primary care services throughout California. The network includes programs that participate in Medi-Cal as either an Indian Health Services – Memorandum of Agreement (IHS-MOA) provider, a tribal FQHC, or an urban Indian FQHC. To participate in the IHS-MOA the Tribal program must operate under the authority of the Public Law (PL) 93-638, 25 USC 450 et seq. The IHS-MOA provider type allows tribal health programs to receive a federally established all-inclusive rate for Medi-Cal covered services.

The FQHC/RHC/IHS-MOA, code conversion establishes HIPAA-compliant procedure code sets for FQHC/RHC/IHS-MOA services and replaces the non-HIPAA-compliant HCPCS Level III codes commonly referred to as local per-visit codes. Providers will be using a combination of revenue codes, revenue codes and CPT-4 or HCPCS codes, or revenue codes and CPT-4 or HCPCS codes with a modifier.
