I'm coding a consult for a cardiologist and he coded prolonged services that included: ~15-20 minutes face-to-face with the patient, speaking to her about her condition and a treatment. He included about that amount of time for reviewing her chart and speaking to the referring physician over the phone. Is this all included in the consult code, or is he right and I'd add on a prolonged service code in addition to the consult code? I've been looking everywhere online for documentation saying that, but I can't find any. Anyone? Is he overestimating time? I asked him his timeline / time spent in a query.
