American Health Information Management Association (AHIMA) Certification Practice Exam

Which publication is considered the best reference tool for ICD-9-CM coding advice?

1. AMA's CPT Assistant

2. AHA's Coding Clinic for HCPCS

3. AHA's Coding Clinic for ICD-9-CM

4. National Correct Coding Initiative (NCCI)

The correct answer is: AHA's Coding Clinic for ICD-9-CM

The AHA's Coding Clinic for ICD-9-CM is considered the best reference tool for ICD-9-CM coding advice because it is specifically designed to provide accurate, up-to-date guidance on the coding and billing aspects of the ICD-9-CM system. It offers official coding advice, clarifications, and detailed explanations to help coders apply the guidelines correctly in clinical practice. The Coding Clinic is published by the American Hospital Association, which has a deep understanding of healthcare coding needs, making it a trusted resource for coders and health information management professionals. In contrast, the AMA's CPT Assistant primarily focuses on current procedural terminology (CPT) and coding advice related to it. Therefore, while it is an excellent resource for CPT codes, it is not relevant for ICD-9-CM coding specifically. The AHA's Coding Clinic for HCPCS addresses the Healthcare Common Procedure Coding System, which is also distinct from ICD-9-CM. Lastly, the National Correct Coding Initiative (NCCI) is geared toward ensuring proper payment for services by reducing improper coding that leads to incorrect reimbursement and is not a primary source for ICD-9-CM coding guidance.
