The ASC I work for has an ophthalmologist that instead of writing/typing out the diagnosis he is just placing the ICD-10 (ex. H25.12) on the reports. I was recently at an E/M Seminar that stated this is a big NO. Can anyone forward me to documentation to support that he is unable to do this and is therefore not compliant?? All I'm finding pertained to E/M coding and not specifically ASC.
