Which coding system is primarily used for procedure coding?

The coding system primarily used for procedure coding is the Current Procedural Terminology (CPT) Codes. CPT codes are utilized by healthcare providers to describe and document the procedures and services they provide to patients. These codes are maintained by the American Medical Association (AMA) and are essential for billing and coding in the healthcare system.

CPT codes cover a wide range of services including surgical procedures, diagnostic tests, and other medical interventions. This specificity and comprehensive nature make CPT the go-to coding system for capturing procedural information accurately in clinical documentation and billing.

While ICD-10 Codes primarily focus on diagnosis coding, documenting the condition or disease that necessitates the treatment, HCPCS Codes are used for both procedure coding and non-physician services, such as durable medical equipment but are not as comprehensive as CPT for procedural descriptions. DRG Codes, or Diagnosis-Related Groups, are used for inpatient hospital billing to classify cases for reimbursement based on diagnoses and procedures but do not serve as a detailed coding system for all procedures.

Hence, the correct answer reflects the main role of CPT codes in procedure coding within healthcare.
