Question

Which of these is used only in the hospital inpatient setting?

A) CPT codes
B) HCPCS codes
C) ICD-10-CM
D) ICD-10-PCS
E) ICD-9-CM Volume I

Answer 1

ICD-10-PCS is used exclusively in hospital inpatient settings for coding procedures. ICD codes, in general, are found on medical lab requests and within health-care management systems, serving purposes like test identification and insurance claim processing.

Step-by-step explanation:

The correct answer to the question "Which of these is used only in the hospital inpatient setting?" is D) ICD-10-PCS. The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) is used exclusively for inpatient procedures within hospitals in the United States.

Other choices, such as CPT codes, HCPCS codes, and ICD-10-CM, are used in varying settings, including outpatient. ICD-9-CM Volume I is an outdated system that was replaced by ICD-10-CM for diagnosis coding. In medical settings, ICD codes are essential for a variety of purposes, from identifying tests in medical laboratories to processing claims for insurance reimbursements.

Moreover, these codes are used by vital-records keepers and epidemiologists for record-keeping and statistical analysis. Two locations where one might commonly find an ICD code would be on a medical laboratory request and within the health-care management system for verifying treatments.
