Days in accounts receivable (Days in A/R) is one of the more commonly referenced metrics in revenue cycle management, and for good reason: it offers a quick read on how efficiently a practice is converting billed services into collected revenue.
What it measures
In general terms, Days in A/R estimates the average number of days it takes a practice to collect payment after a claim is billed. A lower number generally suggests claims are being paid faster; a rising number can be an early sign that something in the billing process needs attention.
What can drive it up
Several factors commonly contribute to a rising Days in A/R figure: claims stuck at a payer without follow-up, a growing backlog of denials, slow charge entry, or inconsistent patient billing. Because the metric is an average, a relatively small number of very old claims can noticeably skew it.
Using it as a diagnostic, not just a scorecard
Days in A/R is most useful when reviewed alongside other detail: which payers, which claim types, and which age buckets are contributing most. That level of detail turns the metric from a single number into a starting point for actually improving the process.
