Medicare OA-121
« on: November 16, 2011, 02:26:31 PM »
Ok so we are billing out a few different procedures 1st patient 35301 & 35301-AS 2nd patient 99213 & 3rd patient 99214. Medicare paid on these but not at the normal rate they are asking us to take our normal Co-45 adjustment and an additional OA-121 (indemnification adjustment). I called Medicare and the lady had no clue. She did say something about outstanding member balance but that she would have to review further and call me back. Can some one please explain to me what this means and is this a provider w/o or patient balance?

I've heard it may be related to PECOS but I haven't encountered it personally.  If she doesn't call back I would call again and get someone else who understands it.  They need to be able to explain it.
