Was is the icd9 code for blood draw?

In ICD-9, there isn't a specific code for a blood draw itself, as ICD-9 primarily categorizes diagnoses rather than procedures. However, the procedure for drawing blood is often associated with the code 99.99, which indicates "other procedures." For more accurate coding related to blood draws, healthcare providers typically use CPT codes instead, such as 36415 for a routine venipuncture.
