when billing for speech therapy - primary ins. is BCBS, or Aetna - visits are not timed, so I put in 1 for 24J (number of units). Then if Medicaid is secondary, I change number of units to 15 min increments since Med. does pay according to timed units, so number of units has to be indicated on the secondary claim. My question is, shouldn't the documentation on daily progress notes show the "time in" and "time out" for each visit? My provider says "no, it's not necessary" to have length of time for the visit on notes, and to just chg certain amt per visit. She chgs an amt for certain code and another amt for another code. She gives me her charges and progress notes for each visit per patient, but doesn't indicate time or how much time per code. She said to chg for 1 hour for each visit. My other ST providers give me their charges with more detailed notes - Each visit has the time in and time out, or how many minutes for that session, and how much time they spent with patient for each code and they are not all the same. If I tell her she really needs to have the time on the notes, will I be telling her the correct thing?
