A/R Recovery: The Aged Claims Hub
Accounts receivable is where revenue goes to die quietly. Claims that should have been paid are sitting in 60+ day buckets because nobody is working them. The collect-rate halves every 30 days a claim ages. This hub is the field manual for systematic A/R recovery — the age-bucket strategy, the follow-up cadence, the payer-specific tactics, and the metrics that separate top-quartile practices from the ones writing off six-figure receivables every year.
What This Hub Covers
Accounts receivable (A/R) is the total dollars owed to a practice by payers and patients for services already rendered. It is tracked in age buckets — 0 to 30 days, 31 to 60, 61 to 90, and 90+ — because the probability of collection drops sharply as a claim ages. A claim worked at day 14 collects at 95%+; the same claim sitting untouched at day 90 collects at 50% or less. By day 180 it is usually a write-off. Healthy practices keep 85%+ of A/R under 60 days. Practices with broken A/R workflows often have 30 to 50% of their receivables sitting past 90 days, representing six-figure annual write-offs even at modest claim volumes.
Days in A/R is the headline metric. It is calculated as total A/R divided by average daily charges. Top-quartile practices keep it under 35 days. Bottom-quartile sit above 60 days. The difference is not the number of billers — it is the discipline of the follow-up cadence. Every claim has predictable touch points: day 14 status check (most clean claims should have an EOB by then), day 30 first follow-up call if no response, day 45 escalation, day 60 supervisor escalation, day 90 final demand or external collection. A specialized A/R team works every age bucket against this cadence on every payer relationship simultaneously.

Why Aged Claims Stop Getting Worked
Every aged-A/R bucket has a predictable failure mode. The 0-30 bucket sits because a claim was submitted but no status check was scheduled at day 14. The 31-60 bucket sits because a denial came back and the biller did not have time to appeal it within the payer's deadline. The 61-90 bucket sits because the appeal was filed but the payer requested additional documentation that nobody routed back. The 90+ bucket sits because the timely-filing window has passed and the biller mentally wrote it off. Each bucket has a different recovery strategy, and a generic biller working in chronological order will always favor the easy 0-30 wins and starve the older buckets of attention. The fix is dedicated A/R specialists working oldest-first by payer.
The A/R Follow-Up Cadence That Recovers Revenue
Every claim should have five scheduled touch points. Day 14: status check via clearinghouse 277CA acknowledgment or payer portal — most clean claims have an EOB by then. Day 30: first follow-up if no payment or denial — call the payer's provider services line, get a claim status code, document the call. Day 45: second follow-up with escalation to supervisor if the day-30 call did not produce action. Day 60: formal status request in writing, usually triggers internal escalation at the payer. Day 90: final demand letter, decision point on external collection. Working every claim against this cadence — instead of working in chronological order — is what keeps days in A/R under 35.
Days in A/R: The Single Most Important Metric
Days in A/R = (Total A/R balance) / (Average daily charges). It tells you how many days of revenue are uncollected at any moment. Top-quartile practices: under 35 days. Median: 45 to 55 days. Bottom-quartile: 60+ days. A practice billing $1.5M annually with 60 days in A/R has $250K in receivables at any time; the same practice at 35 days has $145K. The difference is $105K in cash flow plus a sharply higher collection rate (because the older claims that bottom-quartile practice is carrying are aging into write-off territory). Track days in A/R weekly, broken out by payer.
Aging Bucket Distribution: The Health Check
Healthy A/R distribution: 85%+ under 60 days, less than 10% over 90 days. Unhealthy: 30 to 50% sitting past 90 days. The over-90 percentage is the warning indicator — once a claim crosses 90 days the collection probability drops below 50% and continues to fall. Pulling an aging report monthly and breaking it out by payer reveals the worst-performing payer relationships. A payer with consistent 60+ day aging usually means slow adjudication, frequent additional information requests, or undocumented authorization requirements — all addressable with the right prevention rules.
Patient A/R vs Insurance A/R
Patient-responsibility A/R follows different rules than insurance A/R. Patient balances are governed by the practice's patient billing policy and increasingly by the No Surprises Act for emergency and out-of-network surprise charges. The collection cadence is different — first statement at adjudication, second at 30 days, third at 60, payment plan offer at 75, final notice at 90, external collection at 120 if practice policy allows. Modern practices automate this with billing platforms that handle statement generation, online payment, and payment plans. The error most practices make is treating patient A/R like insurance A/R — chasing it with the same cadence and never offering payment plans, which leaves money on the table.
When to Outsource A/R Recovery
Three signals indicate A/R outsourcing pays for itself: days in A/R above 50, over-90 buckets above 15% of total A/R, or a stack of aged claims that have been sitting untouched for 60+ days because the in-house team cannot get to them. Specialized A/R recovery teams work nothing but aging — they have payer-relationship muscle memory, dedicated time, and contingency-fee economics that align their incentives with collection outcomes. For most mid-size practices, a specialist team can recover 30 to 60% of aged claims that the in-house team had effectively given up on, paying for the engagement many times over.
