Joi Clark

I've supported patient-facing and revenue-cycle operations at Washington University Department of Dermatology and Washington University Medical School, handling insurance verification, pre-authorizations, patient financial responsibility, and accurate medical coding.

As a Medical Coder, I reviewed inpatient, outpatient, and professional-service documentation, assigned diagnosis and procedure codes, and produced quarterly E&M coding reviews to reduce billing discrepancies and support compliance. In my current daycare office role, I manage front-desk operations, scheduling, payment processing, billing data entry, and organized enrollment and financial records.
