What Is Days in AR?

What Days in AR Means

Days in accounts receivable is a key revenue cycle metric that measures collection speed. It answers a simple question: on average, how many days pass between delivering a service and receiving payment? The calculation divides your total outstanding AR balance by your average daily net revenue. If your practice carries $500,000 in AR and generates roughly $15,000 per day in net revenue, your days in AR is approximately 33 days. This number is tracked monthly and compared against specialty benchmarks to gauge billing department performance and overall financial health.

Why Days in AR Matters

Every day a dollar sits in AR is a day your practice operates without that cash. High AR days strain payroll, supply purchases, and growth investments. MGMA data shows that practices in the top quartile for collections maintain AR days around 32, while bottom-quartile practices often exceed 50 days. The gap is rarely about payer speed alone — it reflects how effectively the practice prevents, identifies, and resolves claim denials. A practice that appeals 80 percent of recoverable denials collects faster than one that writes them off or lets them age past timely filing deadlines.

How Days in AR Affects Your Practice

Elevated AR days create a cascading financial problem. Denied claims remain on the books as receivables even though payment is uncertain. Staff spend hours reworking claims that should have been clean on first submission. Patient balances grow while insurance denials remain unresolved, making collections conversations harder. Creditors and potential acquirers view high AR days as a red flag for revenue cycle weakness. For a multi-provider group, the difference between 35 days and 50 days in AR can represent hundreds of thousands of dollars in trapped working capital at any given time.

What to Do About High Days in AR

Pull an AR aging report and segment balances by payer, denial status, and age bucket. Focus first on denied claims over 60 days old — these are closest to becoming unrecoverable write-offs. Implement a denial work queue with daily triage so new denials are categorized and assigned within 24 hours. Track your denial rate alongside AR days to prove the correlation to leadership. For denials that need immediate appeal, upload the EOB to Denial Appeal Pro to generate a targeted appeal letter and stop the clock on aging AR.

Frequently Asked Questions

How is days in AR calculated?

Days in AR is calculated by dividing total accounts receivable by average daily net patient service revenue. The result tells you how many days of billing it would take to collect all outstanding balances at current collection rates.

What is a good days in AR benchmark?

Most well-managed physician practices target 30 to 35 days in AR. Anything above 45 days signals collection problems, often driven by unworked denials, slow payer processing, or weak follow-up on patient balances.

Do denials increase days in AR?

Yes. Denied claims sit in AR while staff investigate, appeal, or resubmit. Each denied claim adds 30 to 90 days to collection time, and claims that are never appealed become permanent AR that inflates the metric.

How can I reduce days in AR quickly?

Work your oldest denials first, improve front-end claim scrubbing to reduce first-pass rejections, and establish a 48-hour turnaround on all new denials. Even a 5-day reduction in AR days frees significant working capital.
