Coding specialists are skilled in classifying medical data from patient records, often in a hospital setting but also in a variety of other healthcare settings. The CCS credential demonstrates a practitioner's tested skills in data quality and accuracy as well as mastery of coding proficiency.  

The CCS certification is a natural progression for professionals experienced in coding inpatient and outpatient records. Coding specialists create coded data used by hospitals and medical providers to obtain reimbursement from insurance companies or government programs such as Medicare and Medicaid. Researchers and public health officials also use this data to monitor patterns and explore new interventions.
