Pt arrives for Complete physical exam. Pt has extended history of cardiotoxic medications (protease inhibitors) and microlides. A 12-lead EKG indicates new-onset atrial fibrillation.

Option 1: along with V70.0 and V58.69 include E930.3 (microlides) and/or E933.8 ((other systemic agents not elsewhere classified)(protease inhibitor)) reflecting new onset atrial fibrillation which may be associated with medications

Option 2: code only for V70.0 and v58.69 only. No E codes since there is not a definative correlation between the the cardiotoxic medications and the new onset atrial fibrillation.

Any input would be much appreciated.

Also, used E933.8 since E931.7 is antiviral, not anti-retroviral. And E949.9 (Other and unspecified vaccines and biological substances) did not seem appropriate because that listing is for other "vaccines."
