We have had a debate going on in our office regarding proper coding of 99213 office visit with an injection. The other coder and myself have coded things the same in the past, but we have recently had others start questioning how we are doing things. If a patient comes in with Lt knee pain and stiffness, and ends up being diagnoised with osteoarthritis of the Lt knee, and gets an injection into the knee, are we able to code as follows:
Dx codes: (A)M17.12, (B)M25.562, (C)M25.662
99213-25 (A,B,C)
20610-Lt (A,B,C)
J1040 (Depo Medrol 80mg) (A,B,C)
We are being advised that we cannot tie the same diagnosis to the office visit as we do the injection. We've been told we should only link the pain (M25.562) and stiffness (M25.662) to the office vist, and the osteoarthritis (M17.12) to the injection.
Anyone with feedback on this would be greatly appreciated...
One "trick" I use to determine what might be considered separately identifiable. I cross off (mentally) anything that has to do with the injection and consider other factors like the reason for visit.
Starting from the top, if the reason for visit indicates that this was a planned procedure in anyway, there is really no room for modifier -25 unless there is another body part addressed.
Initial visits usually always are eligible for modfiier 25 UNLESS it was scheduled as injection and there is no other work-up. This might be the case for fluoro guided hip injections - one provider in the suite may do them while another doesn't.
Diagnosis coding: the pain and stiffness codes are unnecessary. Look at the diagnostic imaging/other outpatient guidelines section in the
ICD-10 book (very front). The wording might be different, but it basically states that once a definitive diagnosis (arthritis) is made, pain and stiffness (being signs and symptoms) should not be reported - they are assumed.
So, now we can mention a couple (may not be all-inclusive) scenarios a modifier 25 should apply:
- new patient visit where this provider is establishing the treatment plan (IE not referred and scheduled for injection only)
- established patient coming in for a new problem to be worked up and proceed with injection same day
- established patient scheduled for injection only, with an additional problem addressed. (you code the progress note according to all the elements not crossed off as already included in the e/m inherent to the injection procedure)
There is a grey area, in my mind, when a patient returns for a three or six month injection. Was it planned? Was there resolution to the prior problem, was it OA or just pain/swelling? These are all factors that would have to be individually considered when a patient returns for a follow-up and has an injection. Like I mentioned, start at the top: was it planned
Lastly, remember that joint injections are 0 day global procedures. 0 day and a 10 day global periods should only be appended with modifier -25. Modifier -57 is only when the global period is going to be 90 days, and the actual full discussion, RBA and decision occurred
on the day of or the day before surgery.
I hope that helps. I can pull the references if you like.
