Wiki Excision of calcium deposits?

[BFAITHFUL]

Doc did an arthroplasty 28285 but also did an excision of pyrophosphate crystals on same digit for calcium deposits, isn't this bundled into the arthroplasty code? If not would I use CPT 29999 for this?

If the crystals were on the same proximal phalanx, I would think it would be considered part of the 28285....just a thought. Esp. if the surgeon didn't have to make a separate incision.
