Health insurance claims review

slide-006.jpg

OCR text:

Background

Background

Health insurers and health funds around the world employ medical reviewers to assess

; whether a requested treatment, procedure, or medication is covered under a patient's

Pf policy. This requires cross-referencing clinical documentation, coverage policies, clinical

guidelines, and patient claims history. It is one of the most administratively intensive

« P| ; roles in healthcare operations.

What we are building

We are building an internal claims review system for a fictitious health insurance

company called MDB Health. This system is used by medical reviewers to assess and

adjudicate claims. The external-facing system through which healthcare providers

submit claims and receive feedback on outcomes is out of scope.
