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
Commonly confused with
- A/R aging: Days in A/R is a single average; A/R aging buckets outstanding balances by age (0–30, 31–60, …) to show where the delay actually sits.
- Net collection rate: Days in A/R measures how fast revenue is collected; net collection rate measures how much of the collectible revenue is ultimately collected.
