Days in A/R

Days in accounts receivable is the average time to collect after care is delivered — a core measure of how quickly a practice turns services into cash.

Updated

Days in A/R (accounts receivable) is the average number of days it takes a practice to collect payment after a service is delivered. It reflects how quickly claims move from billed to paid across all payers and patients.

It is typically derived from total outstanding A/R measured against average daily charges over a recent period — commonly a trailing window such as the last 3, 6, or 12 months.

How it’s calculated

Total accounts receivable ÷ (Total charges over a period ÷ number of days in that period)

Equivalently: total A/R ÷ average daily charges. The charge period (for example a trailing 90 or 365 days) must be stated for the figure to be comparable.

How to read it

A lower days-in-A/R generally signals a healthier, faster cycle, but a reasonable range depends heavily on payer mix and specialty. Read it as a trend over time and alongside an A/R aging breakdown rather than a single target — treat any benchmark as directional, not absolute.

What moves it

  • Clean-claim and denial performance upstream
  • Speed of claim submission and payer turnaround
  • Effectiveness of A/R follow-up on aged balances
  • Timeliness of patient-responsibility collection
