Medical Coding Practice Test

Procedures in subterms procedural coding in ICD-9-CM are classified according to site and/or surgical technique. This means that the procedures are grouped based on where they are performed on the body and the specific surgical techniques used. This classification system helps in accurately coding procedures for medical billing and statistical purposes.

Options A, B, and D are incorrect:

- Option A, based on the patient's characteristics, is not the primary basis for classifying procedures in subterms procedural coding.

- Option B, by using only alphabetical codes, is not the way procedures are classified in ICD-9-CM, as alphanumeric codes (combination of letters and numbers) are used.

- Option D, using a combination of letters and numbers, is partially correct but does not specifically address the criteria of classifying procedures according to site and/or surgical technique.
