Outpatient A/R days ideally land in the high 20s to mid-30s. Past 40, you are floating payer float. Past 50, timely-filing risk rises and write-offs start looking inevitable. When eBillRCM hears “our days crept over 40,” we do not start with opinions — we start with three report cuts.
Cut 1: aging mix
Break open AR into 0–30, 31–60, 61–90, 91–120, and 120+. A workable target mix is roughly two-thirds in 0–30, under a fifth in 31–60, under a tenth in 61–90, and single digits beyond that.
If 91–120 exceeds about 8%, follow-up is lagging. If 120+ exceeds about 6%, claims that should have been appealed or written off are padding the report and distorting management decisions.
Cut 2: days by payer
Recut the same aging by payer. Divide each payer’s AR by their average monthly billed amount to approximate payer-specific days. Medicare often clears in the mid-teens; large commercials often clear in the low-to-mid 20s when submission is clean.
A payer stuck at 45+ without an active appeal queue usually means silent rejections, incomplete demographics, or unworked remits — not “slow insurance.” Corrupted EDI loops and unposted rejection reports are classic culprits.
Cut 3: follow-up cadence
“Someone works the aging when they can” is not a cadence. Define day thresholds and escalate on a schedule: status inquiry after day 25, documented payer contact after day 35, escalation/appeals queue by day 50, and manager-reviewed write-off recommendation by day 70.
The two-week sprint
Meaningful movement in the 60+ bucket often shows within fourteen days when four habits stick:
- 1Freeze scope to the top three payers by aged dollars for the first two weeks.
- 2Name one owner per payer for the 60+ inventory — no shared anonymous queues.
- 3Hold a brief daily stand-up: claims touched, payer responses, blockers.
- 4Re-run aging every Friday and watch only the 60+ dollar total until it moves.
A 15–25% drop in the 60+ bucket in two weeks is common when focus is protected. Overall A/R days usually follow within a month. The hard part is defending those focused hours from every other fire in the office.
