Reducing EVV Claim Denials by 74% for an MLTSS Home Care Agency
A mid-size New Jersey MLTSS home care agency serving 320+ members across Bergen, Passaic, and Essex counties.
!The Challenge
The agency was processing Electronic Visit Verification through a combination of HHAExchange manual entries and paper timesheets. Caregivers frequently forgot to clock in using the mobile app, leading to missing GPS coordinates. Billers spent an average of 12 hours per week reconciling EVV exceptions before submitting claims to Conduent. Denial rates hovered around 18%, primarily due to mismatched visit times, missing member IDs, and late submissions. The agency had already received a corrective action letter from the MCO warning that continued denial rates above 10% could trigger contract review.
âš’The Solution
Via Lucra conducted a two-week discovery engagement that mapped every step of the visit-to-claim lifecycle. We identified three root causes: (1) caregivers were not trained on the HHAExchange mobile app's offline mode, causing data gaps in low-signal areas; (2) the biller had no automated way to flag visits where clock-in and authorization windows didn't overlap; (3) there was no pre-submission validation against the 837P format requirements. We built a Python-based reconciliation pipeline that pulls EVV data from HHAExchange via API, cross-references it with authorization records from the agency's care management system, and generates a nightly exception report. Visits with time discrepancies greater than 15 minutes, missing GPS data, or mismatched procedure codes are flagged for review before claims are batched. We also created a caregiver training module covering offline clock-in, GPS permissions, and common error scenarios.
✓Measurable Results
- Claim denial rate dropped from 18% to 4.7% within 90 days
- Weekly biller reconciliation time reduced from 12 hours to under 3 hours
- MCO corrective action was lifted after two consecutive clean audit months
- Pre-submission validation catches an average of 23 exceptions per week before they become denials
- Agency retained full ownership of the reconciliation codebase and runs it on their own AWS account
