What is your opinion on the ICD-9 Procedure code for an infusion of Remicade for rheumatoid arthritis or Crohn's disease? Since this is considered a high-risk drug, the CPT codes are in the antineoplastic category. But matching up a ICD-9 is not clear. Since Remicade is a biologic response modifier you can go down that path. It is also a monoclonal antibody, so you can go down that path. So far I have come up with 99.28, 99.25, 00.18, and the usual 99.29. What does your facility do? Thanks. No one seems to have a clear answer on it.

This is an interesting question! There does appear to be a lot of room there for confusion. I'm a firm believer in two things . . . reading exactly what the code book says and also using reputable references. So, I'll do both of those here.
You want to code an infusion of Remicade for an immune disorder, not a neoplastic condition. First I'll find the CPT codes, then the corresponding ICD-9-CM procedure codes.
In CPT, the infusion code we want begins with "Chemotherapy administration, intravenous infusion technique. . . "
The section heading above that code says "Injection and Intravenous Infusion Chemotherapy and Other Highly Complex Drug or Highly Complex Biologic Agent Administration."
What is this really saying? Let's look higher up. In the first paragraph of the instructions, it says that these codes apply to anti-neoplastic agents used for noncancer diagnoses and also to substances like these nifty monoclonal antibodies and biologic response modifiers. Note that it isn't saying the monoclonal antibodies and biologic response modifiers are being used AS antineoplastic agents, but just that administration of these substances is included here. It explains that this is because they are both highly complex, etc.
In the next paragraph, it clears up any confusion we might have had about "chemotherapy" turning this stuff into an antineoplastic agent. It says that "chemotherapy" as used in these codes "includes other highly complex drugs or highly complex biologic agents."
So, nothing here ever said the monoclonal biologic response modifier we're coding is an antineoplastic agent, nor did it say that it was being used as an antineoplastic. The codes are just written to include BOTH antineoplastics AND highly complex drugs and biologic agents.
We're just going to use those codes because they're the correct codes for highly complex drugs and biologic agents, and we're going to modify our thinking about a "chemotherapy" agent to include those things.
The AMA's Principles of CPT Coding, Sixth Edition, expands on this some and confirms it.
Now we have a CPT code for a monoclonal antibody that is chemotherapy, yet not antineoplastic. Keeping that in mind, let's look this up in ICD-9-CM.
If we look up Infusion and skim down the entire list, we'll see Infusion, antineoplastic agent, but . . . we don't have an antineoplastic agent. We therefore cannot use 99.25 or 99.28. Infusion, biological response modifier, antineoplastic agent 99.28 has the same problem . . . we aren't coding an antineoplastic agent. No antineoplastic activity is happening here.
On we go until we get to Infusion, therapeutic substance NEC 99.29. And that appears to be the only possible match in that list.
In the tabular list, 99.29 is Injection or infusion of other therapeutic or prophylactic substance.
99.25 is Injection or infusion of cancer chemotherapeutic substance, but this isn't for cancer. 99.28 is Injection of infusion of biological rsponse modifier as an antineoplastic agent, but, again, we don't have any neoplasm.
99.29 is the only possible option. What we're doing isn't specifically excluded from 99.29, either. It isn't going to be 00.18 because 00 is Procedures and Interventions, not elsewhere classified. This is classified as 99.29.
Once you get to the tabular list, it becomes more difficult to sort these out. If you select the code in the alpha index, however, it is quite clear.
You just have to avoid thinking that the drug is "antineoplastic," because nothing in the CPT manual said it was. It appeared that it kind of did, but close reading showed us that it did not say that. Once you eliminate that word from your thinking, the choice in the alphabetic index is clear enough.
I think it is, anyway. :)
