Final answer:
The ICD-9-CM is used for diagnostic coding and classification, while the CPT manual is used for coding healthcare procedures and services for billing. ICD codes are found in medical laboratories and healthcare management systems, aiding in test identification, treatment verification, and insurance claim processing.
Step-by-step explanation:
The big difference between the ICD-9-CM (International Classification of Diseases, Ninth Revision, Clinical Modification) and the CPT (Current Procedural Terminology) manual is their purpose and use in the healthcare industry. The ICD-9-CM is used for coding and classifying diagnoses and reasons for visits in all healthcare settings, whereas the CPT manual contains codes for procedures and services performed by healthcare providers. The ICD-9-CM codes are primarily used for diagnosis reporting and statistical purposes, providing a uniform language for reporting and tracking health conditions. In contrast, CPT codes are used to describe healthcare procedures and services for the purpose of billing and reimbursement. Two locations where you would likely find an ICD code include medical laboratories and health-care management systems. In medical laboratories, ICD codes are used to identify tests that must be performed to confirm a diagnosis. In health-care management systems, ICD codes are used to verify that treatments and laboratory work are appropriate for the patient's diagnosis. Additionally, medical coders and billers use these codes for processing claims with insurance companies.
