Here's why code changes aren't the whole story.
Heads up -- Annual ICD-9 index and note updates can affect your coding, even when related code descriptors don't change.
Case in point:
The ICD-9 committee received a request to create a code for pre-chemotherapy ultrasounds.
The committee decided that because "V codes are reasons for encounter codes, not procedure codes, it would be inappropriate to create such codes" (www.cdc.gov/nchs/data/icd9/agendaMa08.pdf).
Compromise:
ICD-9 may add an inclusion note instructing you to assign V72.83 (
Other specified preoperative examination) for pre-chemotherapy exams.
