Q: I am a new provider in Region C, and I was wondering if you can advise me of any new or deleted codes for 2006 strictly for ankle foot orthoses?

A: According to the Healthcare Common Procedure Coding System (HCPCS) level II, the added codes for this category are L-2034 (knee ankle foot orthosis, full plastic, single upright, with or without free motion knee, medial lateral rotation control, with or without free motion ankle) and L-2387 (addition to lower extremity, polycentric knee joint, for custom fabricated knee ankle foot orthosis, each joint). Effective January 1, 2006, procedure code L-2039 has been discontinued.

Q: I have been billing K-0628 and K-0629 every way Medicare has told me.I am still not getting paid. I was told to use RT/LT modifiers. Then I was told to use KX modifiers. At one point I was told not to use modifiers. I then was told not to use these codes at all. What do I have to do to get paid on these codes?

A: If the date of service you are billing for is after January 1, 2006, the codesyou are using may not be valid anymore. As of January 1, K-0628 was replaced with A-5512, and K-0629 was replaced with A-5513 . If your date of service is prior to January 1, 2006, I would need the denial code or reason listed on the Medicare EOB to further assist you in this matter.
