Most Women's Health Branch programs report some or all of their data to the State through the Health Service Information System (HSIS). This system was developed in the early 80s as a billing system for local health departments. The HSIS manual (PDF, 77 MB) is the description of all the files and features of the HSIS data reporting system. Billing for most programs within Women's Health is done in this system.
Coding in the HSIS uses one of two schemes - CPT codes and ICD codes. These codes are commonly used by Medicare and Medicaid , as well as hospitals and vital statistics. International Classification of Disease (ICD) codes are generally used to describe medical conditions, such as diabetes or prolapsed cord. The ICD coding was developed by the World Health Organization. Current Procedural Terminology (CPT) codes were developed by the American Medical Association. The CPT is a listing of descriptive terms and identifying codes for reporting medical services and procedures.
