10 Reasons Why Home Health Agencies Are Choosing WellSky (Kinnser)
Selecting an EMR is one of the most important operational decisions a home health agency makes.

Common OASIS Documentation Mistakes That Lead to Payment Delays
Common OASIS documentation mistakes, such as incomplete assessments, incorrect diagnosis coding, inaccurate Section GG scoring, medication and homebound-status errors, weak skilled-need documentation, and missing physician signatures, are among the biggest causes of home health payment delays. Because OASIS data drives PDGM reimbursement, most of these errors are preventable with point-of-care charting, strong QA, and AI-powered documentation validation.
Why OASIS Documentation Is Burning Out Your Nurses
OASIS documentation is the CMS-required Outcome and Assessment Information Set that home health nurses complete for Medicare patients. With more than 100 data elements and a Start of Care assessment that takes 60 to 90 minutes, it often follows nurses home as after-hours 'pajama time,' making it a leading cause of home health nurse burnout. AI-powered documentation with human-in-the-loop review can cut charting time and give nurses their evenings back.
