Which function would you expect an MSO to perform besides billing and coding?

• A. Physical therapy.
• B. Surgical operations.
• C. Laboratory testing.
• D. Clinical documentation improvement.

Answer: (D)

This question tests understanding of what an MSO, as a management services organization, handles beyond the billing and coding tasks. An MSO provides administrative and operational support to a medical practice, including processes that ensure documentation and coding align with payer requirements and quality goals. Clinical documentation improvement is the process of ensuring the medical record accurately reflects the patient’s conditions and treatments so that codes and associated reimbursements are correct and compliant. An MSO often leads CDI programs—conducting documentation audits, coordinating clinician queries, and implementing workflows to capture complete, precise information that supports appropriate coding and reimbursement, as well as quality reporting.

The other options describe direct clinical services rather than administrative functions. Physical therapy, surgical operations, and laboratory testing are hands-on clinical activities delivered by clinicians and labs, not services typically provided by an MSO.
