In what setting is Volume 3 of the ICD manual primarily used?

Volume 3 of the ICD (International Classification of Diseases) manual is primarily utilized in hospitals, as it primarily includes procedure codes for inpatient settings. This volume provides the necessary coding resources for various surgical and clinical procedures performed during hospital stays, making it essential for hospital billing and records.

In environments such as outpatient physician offices, pharmacies, and private clinics, different coding systems or other volumes of the ICD may be more applicable. Outpatient settings typically use ICD Volume 1 and 2, which cover diagnosis codes but not procedural codes, while pharmacies do not typically rely on the ICD for their operations, focusing instead on medication-related classifications. Therefore, the context of use in hospitals aligns accurately with the dominant purpose of Volume 3 of the ICD manual.
