We have been getting numerous denials from Horizon for "mismatch of dx code and procedure code". They are valid dx codes (not missing a letter or number, etc) so not sure what the issue is. When we call, they just state you can't bill that diagnosis with 99213 . Example: M23.322 with 99213. Anyone else having this issue? Any input would be greatly appreciated. Thanks
