Why are ICD-9 codes necessary to include on a claim?
  1. They report the procedures performed on the patient
  2. They are the services that are charged for on the claim
  3. They indicate the medical necessity of the service
  4. They indicate the code linkage on the claim
Explanation
Answer: C - ICD-9 codes are necessary on a claim because they indicate the medical necessity for the service. CPT codes are used to report the procedures on a claim, and they are also used to code charges. Code linkage is what connects the procedures to the diagnoses on a claim. Code linkage also demonstrates the medical necessity of a service, but ICD-9 codes, by themselves, do not indicate a code linkage, as they have to be linked with a procedure code.
