I'm new to inpt coding, I have my CPC but not my CCS. I have a patient who presented to the ED with an acute onset L leg weakness. ED note states L leg weakness in addition to TIA. Patient has a history of 2 remote CVA's walks with a cane. My question is would the admitting dx be a late effect of a CVA and also, the discharge diagnosis states: Acute onset L leg weakness (resolving) and hx of CVA - no significant residual symptoms. No mention of TIA. Condition on discharge: neuro symptoms completely resolved. Would the principal diagnosis be TIA? Any help appreciated.
