When coding long-term drug use, are you able to use V58.61 with V58.66 or V58.63 with V58.66? The codes V58.61 and V58.63 both say they exclude (not include) V58.66. Wouldn't that mean that if a patient was on both meds or even all 3 meds, that you could code them each? Or does it mean you can only pick 1 of the 3 codes? Thanks!
