Pre Bill Auditing


Pre-bill Auditing

After 24 years, MARSI is still one of the few companies that can offer pre-bill auditing.

Usually ... In one business day

The obvious advantages are:  improved accuracy, fewer denials, and less chart submission for re-billings, all without increasing A/R days.



Compliance & Auditing

Inpatient Compliance Review.

MARSI’s recommended program provides a pre-bill review of coding assigned by the facility for the most appropriate MS-DRG assignment.

The pre-bill process eliminates the need for re-submission of these claims, thereby reducing any “red flags” for review by CMS.
