Accounts Receivable Management in Healthcare: Best Practices for Reducing AR Days

AR Aging Analysis Framework

AR aging buckets — 0–30, 31–60, 61–90, 91–120, 120+ days — provide a structural view of receivables. The health benchmark: more than 75–80% of AR should be in the 0–60 day bucket. AR aging greater than 90 days is a warning indicator; AR greater than 120 days represents a collection risk requiring active management. Analyze AR aging separately by payer class (commercial insurance, Medicare, Medicaid, self-pay/patient) — each payer class has different expected payment timelines and collection strategies. Aging analysis by payer identifies systematic payment delays: if one payer's claims are consistently aging past 60 days, investigate whether claims are being submitted correctly, whether there's a payer system issue, or whether specific denial codes are holding up payment on that payer's claims.

Payer-Specific Follow-Up Strategies

Follow-up timelines should be calibrated to payer payment expectations: Medicare and Medicaid typically pay clean electronic claims within 14–21 days; commercial payers within 15–30 days. A claim that has not received a response (payment or denial) within the payer's typical payment window should trigger proactive follow-up. Best practices: establish payer-specific follow-up triggers (e.g., follow up on Medicare claims at 21 days, commercial at 30 days); automate claim status inquiry through EDI 276/277 or payer portal automation where possible; create payer-specific denial patterns and address them at root cause (if a specific commercial payer regularly denies for a specific reason, fix the root cause rather than just working the same denial repeatedly); and maintain payer contact information, appeals deadlines, and portal access credentials in a centralized resource for follow-up staff.

Working Denials Efficiently

Denials in the AR queue should be triaged by: dollar amount (work high-dollar denials first); timely filing deadline (denials where the appeal window is closing should be priority regardless of dollar amount); and denial type (clean correctable denials — billing errors, missing information — should be resubmitted quickly; complex medical necessity denials requiring clinical documentation and appeal letters require more time). Denial working workflow: categorize the denial code; determine if the denial is correctable (resubmit) or requires appeal; assign to the appropriate staff (coding appeals require coding expertise; clinical appeals require clinical documentation); track the appeal response; and escalate to senior appeal or external appeal if the initial appeal fails. Every worked denial that results in payment should feed back into root cause analysis — if the same denial type recurs, the workflow generating it needs to change.

Patient AR and Self-Pay Collections

Patient responsibility AR (balances after insurance payment or for uninsured patients) has grown with high-deductible health plan adoption — patient collections now represent a larger share of practice revenue. Patient AR strategy: collect at the point of service (co-pays, outstanding balances, and estimated responsibility for scheduled services) using a systematic collections at time of service policy; offer payment plans for balances patients cannot pay in full (a structured payment plan with automated payments collects more than periodic statements); use automated patient statement and text/email payment reminder workflows before forwarding to collections; and establish a financial counseling or financial assistance screening pathway for patients who may qualify for charity care or Medicaid. Patient balances forwarded to third-party collections after 120+ days represent a revenue loss AND a patient experience failure — investing in pre-service financial engagement prevents both.

Write-Off Policies

Write-off policies protect against two failure modes: writing off collectible accounts too early (leaving revenue on the table), and carrying uncollectible accounts in AR too long (inflating reported AR and masking real performance). Write-off criteria should be specific and documented: timely filing write-offs (claims filed after the payer's timely filing deadline, past all appeal options); contractual adjustments (the difference between billed charges and contracted rates, written off as a contractual adjustment); bad debt write-off (patient balances forwarded to collections and returned as uncollectible after the defined collection period). All write-offs should require authorization above a defined threshold — write-offs above $X require supervisor or manager approval, write-offs above $Y require CFO approval. Audit write-off patterns regularly to ensure accounts are being written off correctly — high write-off rates without corresponding denial or collection activity can be a sign of fraudulent write-offs or systematic billing problems being buried.
