Cutting Days in A/R: A Cash Flow Playbook for Practices

You earned the money. The claim went out. And now it sits — in accounts receivable, aging by the day, funding nothing. For most practices, cutting days in A/R is the single fastest cash win available: no new patients, no new services, just collecting what you've already earned, faster and more completely.

Why A/R is the hidden cash lever

Extended A/R cycles force a practice to fund payroll, rent, and supplies out of pocket before revenue converts to cash. The longer claims age, the more the practice is effectively lending money to its payers, interest-free. Reducing days sales outstanding (DSO) releases cash you've already earned — which is why it's the first place a fractional CFO looks.

Where A/R breaks down

A high A/R number is a symptom. The cash is trapped for specific, fixable reasons that cluster in a handful of places:

• Front-end breakdowns — incomplete registration, missed eligibility checks, missing prior authorizations.
• Documentation and coding gaps — incomplete notes delay submission; wrong codes trigger denials.
• Slow submission — charges that sit before billing; every day of lag adds a day to A/R.
• Weak follow-up — denials not worked and aged claims not chased, quietly becoming write-offs.
• Untracked payer rules — each payer's requirements missed, producing predictable repeat denials.

Collectibility falls off a cliff after 90 days. The goal isn't just a lower average — it's pulling claims forward before they cross into the zone where recovery becomes unlikely.

The playbook: cutting days in A/R

1. Fix the front door — real-time eligibility verification and prior-auth workflow before the visit.
2. Tighten charge capture and coding — close documentation gaps and get charges out within 48 hours.
3. Run a denial root-cause sprint — fix the top five denial reasons by payer and resubmit the recoverable backlog.
4. Systematize follow-up — work queues by aging bucket and payer, appeal deadlines tracked.
5. Manage patient balances — real-time estimates, card-on-file, and standard payment-plan terms.
