Had a pt have recession 1-tooth while she was in cancer treatment. Checked with Gd, no prior history of any recession, anywhere. Pt feels the cancer treatment she was under contributed to recession. BCBS has denied this claim, saying the code 41870 is an incorrect code. I also used ICD-10 Z92.21 and K06.0 I am really at a loss. Is there a correct CPT code or not? Please help!!! Julie
