Final answer:
CPT codes are not typically reported for an inpatient hospital encounter; instead, ICD-10-CM codes, HCPCS codes, and DRG codes are used. ICD codes are found in medical laboratories and health-care management systems to identify tests and verify treatments.
Step-by-step explanation:
In the context of an inpatient hospital encounter, the code that is typically not reported is CPT codes. CPT codes are used primarily for outpatient services and some procedures, whereas ICD-10-CM codes, HCPCS codes, and DRG codes are often used in the inpatient setting. ICD-10-CM codes are used by clinicians and laboratories to identify illness, guide treatment, and confirm diagnoses. DRG codes are utilized for hospital billing and reflect the patient's severity of illness and resource consumption. HCPCS codes, which include a range of services, are also used in various medical billing and reporting scenarios.
Two locations you would likely find an ICD code would be in medical laboratories, where they are used to identify tests confirming a diagnosis and in health-care management systems, where they verify that treatments and lab work are appropriate for a diagnosed virus.
