Which manual contains the codes and guidelines for outpatient and inpatient procedures?

The correct answer is CPT, which stands for Current Procedural Terminology. This manual provides a comprehensive listing of codes, descriptions, and guidelines for various medical procedures and services performed in both outpatient and inpatient settings. It serves as a standardized system for reporting these procedures, ensuring clarity and consistency across healthcare documentation and billing processes.

CPT codes are integral for a range of specialties and various healthcare settings, covering services such as surgeries, medical services, and diagnostic tests. These codes allow healthcare providers to communicate effectively about the services rendered and facilitate accurate billing and reimbursement from insurance companies.

Though ICD-10-CM is an important coding system used primarily for diagnosis coding, and HCPCS (Healthcare Common Procedure Coding System) includes additional codes for services not covered by CPT, it is the CPT that specifically focuses on the detailed classification of procedures and services. This makes it essential for anyone involved in medical coding and billing to thoroughly understand and utilize the Current Procedural Terminology manual.
