For general acute care hospitals, skilled nursing facilities, or psychiatric hospitals, use the license number issued by the California Department of Public Health (CDPH).

For health care service plans or disability insurers, including Medi-Cal managed care plans, use the license number issued by the Department of Managed Health Care (DMHC) or the California Department of Insurance (CDI), or the risk-bearing organization (RBO) number.

For Medi-Cal managed care plans that are not licensed by the DMHC or the CDI, use the contract number issued by the Department of Health Care Services (DHCS).

For clinical laboratories, use the laboratory license number issued by the California Department of Public Health (CDPH). Do not the federally-issued Clinical Laboratory Improvement Amendments (CLIA) number.
