Coding & Auditing for Hospitals

Physician Education and Documentation Improvement

Auditing Hospitals for Compliance and Defensible Revenue.

MARSI provides expert inpatient & outpatient auditing and coding services which are innovative, proven and provide real results.


MARSI’s recommended program provides a pre-bill review of coding assigned by the facility for the most appropriate MS-DRG assignment without interruption to the billing cycle.

The pre-bill process eliminates the need for re-submission of these claims, thereby reducing any “red flags” for review by CMS. The review process includes physician queries, physician education and CDI specialist and coding staff training.
