The Carlyle Group-backed CorroHealth, a provider of reimbursement cycle tracking services, completed the acquisition of ParaRev, a accounts receivable recovery and resolution service provider, from Housatonic Partners, a private equity investment firm. Financial terms were not disclosed. “The ParaRev team has excelled in taking on and delivering in several niche areas in the RCM space. These areas are typically overlooked by the various vendors in the space. Focusing on these often-ignored opportunities including zero-balance underpayments and denial recovery will be a valued offering for the clients we serve,” Pat Leonard, CorroHealth CEO.
