Scribing.io Automation

The AI scribe automatically detects key phrases such as "perforated TM," "tympanic membrane rupture," and "eardrum perforation." It maps anatomical descriptors (right/left) and temporal indicators (acute/chronic) to appropriate codes. The system also flags when documentation is insufficient for proper coding, such as missing laterality or acuity status.
