Q: When I started as a coder, I learned that the complication code, such as from ICD-9-CM series 998 or 999, takes precedence as the reason of admission when present with another contributing condition. Is this correct, and is there any written guidance from AHA Coding Clinic for ICD-9-CM/ICD-10-CM/PCS that discusses this?

Q: A patient comes in with a malunion of a fracture.

Q: How would the following be viewed if it was included in a cardiology consult note: Mr. Jones has paroxysmal atrial fibrillation. He had a recurrence last night which was asymptomatic. We think this happens all the time at home. This is not a pacing post-conditioning (PPC). He is back in normal sinus rhythm (NSR). I would restart his warfarin if Dr. Smith will allow. Goal International Normalized Ratio (INR) is 2-3.
