I am in WI. Our MA policy says for billing 90862, we must use rounding guidelines they provide. Basically it says 15 min= 1 unit. Therefore 30 min= 2 units. Alot of times we do have 30 min 90862's. Is it appropriate to bill 2 units to MA and only 1 unit to all other payors? MA is saying bill this way, but I have concerns billing 2 units to them and only 1 everywhere else. I would appreciate some feedback on this issue. Would this fall under billing differently to different insurances to get paid more? I know thats a no no. I just don't know what to think.
