The decision
Define which claim fields the assistant may prepare and which decisions require a qualified reviewer. Separate routine data entry from code selection, medical-necessity decisions and payer-specific judgment. A broad billing service description does not establish an individual's credentials.
What to compare
Ask candidates to work through a de-identified rejected-claim scenario and document the next action. Check their experience with your practice-management system and clearinghouse. Confirm how they will record submissions, rejections and pending information.
Before you commit
Measure clean handoffs and rework alongside throughput. Keep access scoped to the job and retain a supervisor for exceptions. A claims assistant is useful when the queue and approval rules are explicit.
