onychomycosis

“Has anyone else noticed Novitas is not approving E/M codes for treating onychomycosis medically? I saw a patient for evaluation of a discolored toenail. She was concerned it might be a fungal infection and wanted to treat the condition before it worsened. I obtained an H/P, a specimen for culture and discussed treatment options depending on culture results. I billed CPT 99212 with diagnosis code B35.1. The EOB read $0 payment. Code 49 “These are non-covered services because this is a routine exam or screening procedure done in conjunction with a routine exam. Any advice?”

“Can you evaluate and manage onychomycosis without debridement for the purpose of treating onychomycosis for an established patient? This would be in the absence of pain and underlying conditions, specifically with Medicare patients. Is it a covered condition for just evaluation and management? Would tinea pedis be covered as a sole diagnosis for evaluation and management?”
