Has anyone been able to bill Medicare for a periprostatic hydrogel injection that was done by a urologist? Initially billed code 45999 (without a description), which was denied. I didn't try to rebill code 45999 with a description because I found code C9743 should be used for dates of service 10/1/15 - 12/31/16 (my DOS is 4/19/16). MAC denied code C9743 for Part A use only.
