Recovering $1.2M in Stalled Claims for a Multi-Site Cardiology Group
A 12-provider cardiology group had 90+ days of aging A/R and a growing denial rate. A full claims audit plus a 48-hour appeal workflow recovered over $1.2M in stalled revenue within two quarters.

Regional Cardiology Partners came to Nevinex with a familiar problem: a growing practice, an aging billing system, and a denial rate that kept climbing every quarter. Their internal billing team was stretched across scheduling, coding, and collections, with no time left to chase down claims older than 60 days.
We began with a full historical claims audit spanning 18 months, which surfaced a recurring coding pattern responsible for nearly a third of all denials — a modifier error specific to a handful of high-volume cardiology CPT codes. Alongside the audit, we stood up a 48-hour denial appeal workflow so nothing new was allowed to age past the point of easy recovery.
Within the first quarter, the practice saw its denial rate drop by more than half. By the end of the second quarter, over $1.2M in previously stalled claims had been recovered, and average days-in-A/R had fallen by 18 days. We now run the practice's full revenue cycle, from charge capture through payment posting.
Nevinex found revenue we didn't know we were losing. The 48-hour denial appeal process alone recovered six figures in the first quarter, and their coding audit stopped the same errors from recurring.
