Which coding system is used to classify diagnoses in any health care setting?

The coding system used to classify diagnoses in any health care setting is ICD-10-CM. This system is specifically designed for the documentation of various diagnoses in healthcare, making it essential for billing, insurance claims, and maintaining patient records. ICD-10-CM, which stands for the International Classification of Diseases, Tenth Revision, Clinical Modification, allows for detailed coding that encompasses a wide range of health conditions and diseases. It helps healthcare providers communicate about patient diagnoses accurately and uniformly.

Other coding systems serve different purposes. For instance, HCPCS Level II is primarily focused on coding for outpatient services, durable medical equipment, and supplies rather than diagnoses. CPT, or Current Procedural Terminology, is used to report medical procedures and services rather than diagnoses. ICD-10-PCS is specifically for coding inpatient hospital procedures, not diagnoses. Therefore, the specificity and applicability of ICD-10-CM make it the correct choice for classifying diagnoses across healthcare settings.
