Direct answer: Medical billing companies can prepare and submit claims, post payments, manage rejections and denials, work A/R, support patient billing and provide reports. The exact responsibilities depend on the written scope and systems used.
Turn clinical and front-end information into billable work
The billing process begins with complete patient, coverage, provider, location, authorization, documentation and charge information. A billing company may validate those inputs and return missing items, but the practice remains responsible for timely clinical documentation and accurate front-end data.
Move claims through submission, payment and exceptions
Assigned work may include claim edits, clearinghouse submission, acknowledgment monitoring, corrections, payment posting, denial follow-up, underpayment review and patient balances. Ask how each exception becomes visible and who owns the next action. The denial workflow guide shows why generic “follow-up” is not enough.
Separate included, optional and retained responsibilities
Coding, credentialing, authorizations, statements, calls, refunds, old A/R and custom analytics may be included or priced separately. Require a responsibility matrix and compare it with the agreement. The medical billing services page provides a complete implementation-oriented framework.
When the scope is documented, compare billing companies around the same work.
