Which coding system is utilized to report diseases, injuries, and other reasons for both inpatient and outpatient encounters?

The coding system utilized to report diseases, injuries, and other reasons for both inpatient and outpatient encounters is indeed ICD-10-CM. This system, which stands for the International Classification of Diseases, 10th Revision, Clinical Modification, is specifically designed for the classification of health conditions and diseases. It is widely used in various healthcare settings to ensure uniformity and accuracy in medical coding, which is essential for billing, statistical analysis, and health care management.

ICD-10-CM codes are alphanumeric and allow providers to specify diagnoses in detail, capturing the type, severity, and location of health issues. This is crucial for healthcare providers and insurance companies to determine coverage, reimbursement, and the overall understanding of patient care needs.

Other coding systems mentioned serve different purposes. For example, CPT (Current Procedural Terminology) is primarily used to report medical, surgical, and diagnostic procedures and services, rather than diseases. HCPCS (Healthcare Common Procedure Coding System) Level II codes are used for products, supplies, and non-physician services that are not covered by CPT. On the other hand, ICD-10-PCS (Procedure Coding System) is specifically designated for inpatient hospital settings only and is used to code surgical procedures, not diagnoses.
