What is a healthy days in AR?
Days in AR is the average number of days it takes to collect a dollar of revenue from date of service, calculated as (Net AR / Average Daily Net Charges).
Quick answer
Healthy days in AR is under 40 days for most outpatient practices. HFMA MAP Keys defines under 30 days as the high-performer threshold; 30–40 days is the healthy band; above 60 days indicates revenue cycle dysfunction.
The detail
HFMA MAP Keys, the industry-standard revenue cycle KPI set, defines net days in AR under 30 as the high-performer threshold, 30–40 days as the healthy band, and above 60 days as concerning. The median across healthcare specialties typically lands at 40 to 50 days. AR over 90 days as a percentage of total AR is the companion metric: under 15 percent is healthy, over 25 percent indicates collection breakdown. Specialty matters: dermatology and dental practices with high cash-pay mix often run under 30 days; behavioral health and orthopedics with heavy commercial insurance often run 45 to 55 days. The biggest drivers of high AR days are slow eligibility verification, claim submission delays beyond 48 hours from date of service, denial backlog, and patient AR collection breakdown. Reducing AR days from 50 to 40 on a $5M practice releases roughly $137,000 of working capital one time and improves cash flow predictability permanently.

From Sorso
Days in AR is the single best leading indicator of revenue cycle health. Track it monthly. If it drifts up by more than 5 days quarter over quarter, something specific broke and you can usually find it within a week.

A good clean claim rate is 95 percent or higher on first submission, per HFMA MAP Keys. Most outpatient practices average 85 to 92 percent, leaving meaningful revenue stuck in rework.
What is a healthy denial rate?
A healthy initial denial rate is under 5 percent of submitted claims, with denial write-offs under 2 percent of net patient revenue per HFMA MAP Keys. Industry averages have climbed above 11 percent.
What is the average net collection rate?
The average net collection rate for healthcare practices is 95 to 99 percent, with HFMA MAP Keys high-performer threshold at 98 percent or higher. Below 95 percent indicates meaningful revenue leakage.
How do I improve my net collection rate?
Improve net collection rate by working denials promptly (60 to 75 percent recovery achievable), reconciling contractual underpayments, collecting patient AR at point of service, and tightening write-off authorization workflows. Most practices can recover 1 to 3 percentage points within 6 months.
