What are the two major types of coding used in healthcare?

The correct answer highlights the two major types of coding in healthcare: diagnostic coding and procedural coding.

Diagnostic coding involves the classification of diseases, conditions, and injuries, which helps in identifying patient diagnoses for billing and statistical purposes. It uses standardized codes from systems like the International Classification of Diseases (ICD), which enables healthcare providers and insurers to communicate about patients' conditions accurately and efficiently.

Procedural coding, on the other hand, encompasses coding for the procedures, treatments, and services provided to patients during their healthcare encounters. This coding uses systems like the Current Procedural Terminology (CPT) or the Healthcare Common Procedure Coding System (HCPCS) to ensure that the specific interventions applied to patients are documented and billed appropriately.

Together, these two coding types form the backbone of healthcare documentation and billing, ensuring that diagnoses and the corresponding treatments are meticulously recorded for both clinical and financial purposes.
