Edits to HCPCS codes G0398-G0400 have been included in the October Update to the 2008 Medicare Physician Fee Schedule Database.

G0398-G0400 have been edited to allow  -26 and -TC modifiers. Besides this allowance, PC/TCs have been changed from 0 to 1. The modifications allow home sleep tests to be split into professional and technical components.

The changes are retroactive to March 13, 2008.
