Summary
Connecticut Medicaid has implemented a review process for claims denied due to exceeding NCCI Medically Unlikely Edit (MUE) limits. Providers can now submit appeals for claims with EOB code 770 by resubmitting electronically with excess units on a separate line using GD modifier, plus required documentation.
Action Required
For Connecticut Medicaid claims denied with EOB code 770 (MUE Units Exceeded): Billing team must resubmit electronically following Provider Bulletin 2017-49 guidelines. Split denied services into two detail lines - first with allowed MUE units, second with excess units using GD modifier. Include paper attachment with cover letter containing original ICN, appeal explanation, and medical necessity documentation. Fax or mail to DXC Technology per Provider Bulletin 2017-49 instructions.
