Skin neoplasm codes go the way of 5th digits

All 173 codes are now 5th digits, following the recent trend in neoplasm codes. The bigger issue with these five-digit codes is that CMS has only designated 173.09 as a case-mix code, not the other codes. This takes away our case-mix codes. Almost all neoplasm 173 codes were all case-mix before the 2012 list came out. That should not be done without rulemaking, so there are may queries in to CMS about this issue.

Remember that the codes follow a patter with the 5th digit:

0 = unspecified

9 = other specified (and this is the case-mix code)

Also remember that the codes affected are not melanoma codes.
