Our practice has experienced a new trend recently with BCBS, Humana and Wellcare mostly, where 99214 office visit is denied for the diagnosis codes submitted. An example is a patient with 99214 and dx codes of M25.511 Bilateral shoulder pain, M25.569 Pain in joint of lower leg, M25.561 Arthralgia of right knee, M51.36 Degenerative disc disease, W19.XXXXA Fall. Those are all the dxs the provider addressed during the visit, so we're not sure where we're going wrong with the dx codes submitted on the claim. Any help is much appreciated!
