Common Reasons Claims Move Into 31+ Day Aging
Most claims don't become aging claims overnight.
They enter the 31+ day bucket because small issues weren't addressed early in the revenue cycle.
What Commonly Causes Delays?
• Eligibility issues identified after submission
• Missing or incorrect authorizations
• Claim rejections not corrected promptly
• Documentation pending provider completion
• Payer requests for additional information
• Delayed follow-up on unpaid claims
• Payment variances and underpayments left unresolved
Why It Matters
Once claims move beyond 30 days, collections slow down.
The longer a claim remains unresolved, the greater the risk of:
• Increased AR days
• Higher administrative costs
• Delayed cash flow
• Escalation into 60+ and 90+ aging buckets
What High-Performing RCM Teams Do
✔ Monitor claims before they age
✔ Prioritize unresolved claims daily
✔ Follow up on payer requests immediately
✔ Resolve rejections before they become AR issues
✔ Track aging trends by payer and denial reason
Aging claims are often a symptom of workflow gaps not payer delays.
The goal isn't just to work old AR. It's to prevent claims from getting there in the first place.
