Answer 1

All ICD-9-CM codes require minimum four digits.

Step-by-step explanation:

True.

All ICD-9-CM codes do require a minimum of four digits. These codes are used to classify and report medical diagnoses and procedures. Each code is made up of three to five digits, with the first three digits representing the category of the diagnosis or procedure. The fourth digit provides additional specificity, and in some cases, a fifth digit is used for even more detailed classification.
