What is the difference between ICD-10 and CPT coding?

The distinction between ICD-10 and CPT coding is fundamental in medical coding and billing. ICD-10, which stands for the International Classification of Diseases, 10th Revision, includes codes that specifically designate diagnoses and the reasons for patient encounters. These codes classify diseases and health conditions, providing a standardized way to document medical conditions, track health statistics, and report to insurance and governmental agencies.

On the other hand, CPT, or Current Procedural Terminology, codes are used to report medical, surgical, and diagnostic services and procedures performed by healthcare providers. These codes help in billing for services rendered to patients and are crucial for reimbursement purposes. They describe the actual treatment or diagnostic services provided during a patient visit.

The correct answer highlights these roles by stating that ICD-10 codes are for diagnoses, while CPT codes refer to procedures and services, accurately reflecting the purpose and use of each coding system in healthcare settings. This clear differentiation helps maintain organizational, billing, and reporting integrity in medical practices.
