Fatu Dingay

Eight years of accurate, high-volume data entry across medical billing, insurance claims, and financial services records. Comfortable working with CPT codes, ICD codes, procedure modifiers, and patient demographic data in systems where an error in entry creates a problem three steps downstream. Trained eye for spotting missing or inconsistent data before it moves further into the process.

Background covers both sides of the claims workflow: entering and validating charges on the billing side, and investigating and settling claims on the insurance side. HIPAA-compliant handling of protected health information is a daily practice. Works well in queue-based environments where accuracy and throughput both have to hold at the same time
