The coding system primarily utilized for hospital outpatient services is the Current Procedural Terminology (CPT). CPT codes are specifically designed to represent procedures and services performed by healthcare providers, making them essential for billing and documenting outpatient care. These codes reflect the clinical services provided to patients, which is crucial for reimbursement by insurance companies and Medicare.

While the International Classification of Diseases (ICD) is important for diagnosing conditions, its focus is primarily on inpatient settings and disease classification. The Healthcare Common Procedure Coding System (HCPCS), although relevant for outpatient services, mainly serves as a supplement to CPT and is used for items and services not covered by CPT codes, such as durable medical equipment. Diagnosis-related Groups (DRGs) are primarily associated with inpatient hospital services and are used for payment purposes based on diagnoses rather than specific outpatient procedures. Hence, CPT is the most applicable coding system for outpatient services in hospitals.
