This is the first time I’m writing here. I have a strange claim that was denied with CO 252 code and the appeal wasn’t successful either. The clinical was attached but they still say that after consideration they don’t think that the visit is as complex as they need for 99205 (new patient). Here are they ICD-10s that were billed accordingly:
R10.84 Generalized abdominal pain
R11.2 Nausea with vomiting, unspecified
F41.9 Anxiety disorder, unspecified
F41.0 Panic disorder without agoraphobia

What am I doing wrong?

Thanks!
