Wiki AS modifer CPT 27447

[ds1317]

We billed this CPT 27447 with an AS modifier to Medicare and received a rejection of the procedure is inconsistant with modifier used or a required modifier is missing. Does anyone know if even though in the description of the procedure it states (total knee anthroplasty) if we need the LT/RT modifiers? When we called Medicare they stated the AS modifier was correct but required an additional modifier.

If there was nothing else done that would require another modifier I would guess it is the LT/RT although we have not had a problem with that ourselves.

I agree with Tina, I never had a problem billing with -AS modifier alone if nothing else was done

That's odd coming from Medicare, I bill this code all the time with only the -AS modifier. I've never once received a denial, I suggest you appeal this.

I recently had the same issue with Medicare. As I have never had this issue before and no other modifier was required, I just appealed the denial. There is no reason to not pay the claim. Maybe this is a new "glitch" with Medicare??
