Claim denials and prior-authorization delays are pushing days in accounts receivable higher, with industry median AR days up 2.4 days in 2026, K-38 Consulting said.
On Tuesday, October 13, 2026, K-38 Consulting reported that medical practices are facing longer accounts receivable cycles, with industry-wide median days trending up by 2.4 days in 2026.
Initial claim denial rates reached 11.8% industry-wide, up from 10.2%, driven by Medicare Advantage prior authorization backlogs and payers deploying AI-driven audit tools; each denied claim adds an estimated 15 to 30 days to the cycle.
Cardiology, orthopedics, and oncology practices absorbed a disproportionate share of the 2026 AR days increase; for a $5 million billing practice, a 10-day increase ties up roughly $137,000 in working capital.
Dallas Alford, founder of K-38 Consulting, advises practices to "track AR days alongside an aging report broken out by payer and denial category," warning that aggregate averages mask concentration problems.
Tightening front-end processes—eligibility verification, authorization confirmation, and clean claim submission—prevents delays before they occur, K-38 Consulting recommends, benchmarking against Medical Group Management Association norms since healthy AR days vary meaningfully by specialty.
