What are M codes used for in ICD-9-CM?

Identify anesthesia codes
Identify neoplasm behavior and cell type
Identify cardiovascular conditions
Identify infectious diseases

The correct answer is: Identify neoplasm behavior and cell type

M codes in ICD-9-CM are used to identify neoplasm behavior and cell type. Neoplasm behavior codes describe whether a tumor is benign, in situ, malignant, etc., while neoplasm cell type codes specify the histology or cellular composition of the tumor. This information is crucial for accurately coding and classifying cancer diagnoses in medical records. The other options listed do not align with the purpose and usage of M codes in ICD-9-CM.
