Medicare, BlueCross are denying any quantity over 3. However, we have 6 specimens with a stain performed on each specimen. We are reporting out 88342 x 6. Medicare and Blue CRoss are only paying 3. We have tried Line 1 88342 3 units, Line 2 88342-XS 1 unit, 88342-XS 1 unit, 88342-XS 1 unit and we have tried modifier 59. Is anyone else having this issue and if so how are you getting your claim paid. Any help appreciated.
