Wiki icd9 s/p THA

What is the THA? If unknown or not specified throughout the note, I would query?
Total hip arthroplasty

If it is transient hemispheric attack (transient ischemic attack) I would use 435.9 for intermittent cerebral ischemia
 
Common abbreviation for total hip, so for s/p I would use a V54.x for aftercare following joint replacement with the V code for the joint replacement or the V67.x for follow up with the V code for the joint replacement.
