Summary
This is a new utilization management policy from Med Mutual emphasizing the CMS Two-Midnight Rule for inpatient admission appropriateness. The policy reinforces that inpatient stays must be clinically justified with two or more midnights of expected care, requires stronger documentation of medical necessity, and encourages use of alternatives like observation services and outpatient management. Billing teams must ensure providers document severity of illness, risk of deterioration, and failed outpatient treatments to support admission decisions and avoid claim denials.
Action Required
Immediately: (1) Billing team must update prior authorization workflows to enforce the Two-Midnight Rule standard for all inpatient admission requests submitted to Med Mutual. (2) Providers must be notified in writing that all inpatient admissions require documentation of: severity of illness, risk of deterioration, failed outpatient/observation treatment (when applicable), expected length of stay, and clinical justification for inpatient-level care. (3) Front-desk and pre-authorization staff must add checklist items to the admission review process requiring verification of two-midnight expectation or documentation of clinical exceptions (high deterioration risk, inpatient-only procedure, complex care needs). (4) Update EMR templates and encounter forms to prompt providers to document these elements at admission. (5) Train billing and coding staff on case-by-case exceptions allowing admission under two midnights when clinically justified. Failure to comply will result in claim denials for admissions that do not meet Two-Midnight Rule standards or lack supporting documentation.
