🎯 Quick Answer: How Do You Clean Up AR Before Year End?
Year-end AR cleanup is a 30-day push to collect or resolve every open receivable before January 1. Work it in four weekly steps:
- Triage: Pull aged AR, flag timely filing risks, post unapplied cash, list open denials.
- Payer push: Check claim status, resubmit, correct, appeal and dispute underpayments.
- Patient balances: Collect 2026 balances before new deductibles start — statements, text-to-pay, plans.
- Close & prepare: Refund credits, apply write-off policy, re-verify January eligibility, set 2027 targets.

📈 1. Why Q4 Is the Best Time to Clean Up Accounts Receivable
Accounts receivable (AR) is money your organization has earned but not yet collected — from insurers and from patients. Every month it sits, the chance of collecting it drops. The last quarter of the year is the most important time to clean it up, because three deadlines line up at once:
| Factor | October–December | After January 1 |
|---|---|---|
| Patient deductibles | Many patients have met their deductible; payers cover more of each claim | Deductibles start over; patients owe more for every visit |
| Old patient balances | Patients can still pay before new costs pile up | 2026 balances compete with brand-new 2027 bills |
| Timely filing | Late-2025 dates of service are near their Medicare 12-month limit | Claims past the limit are usually unpayable |
| Payer & staff capacity | Normal through mid-December | Holiday closures, PTO and January volume surge |
| Financial reporting | Time to fix credits, write-offs and unposted cash | Errors carry into year-end close and audits |

🔄 2. The January 1 Deductible Reset: What Changes for 2027
Most patients start 2027 with a fresh deductible, and high-deductible plans keep getting higher. The IRS minimum deductible for an HSA-eligible high-deductible health plan (HDHP) rises to $1,750 for self-only and $3,500 for family coverage in 2027 (from $1,700 and $3,400 in 2026). Out-of-pocket maximums rise to $8,700 and $17,400.
| Figure | 2026 | 2027 |
|---|---|---|
| HDHP minimum deductible — self-only | $1,700 | $1,750 |
| HDHP minimum deductible — family | $3,400 | $3,500 |
| HDHP out-of-pocket max — self-only | $8,500 | $8,700 |
| HDHP out-of-pocket max — family | $17,000 | $17,400 |
| Medicare Part B annual deductible | $283 | Announced by CMS later in 2026 |
What this means for your AR: a patient who owes you $400 from 2026 will, in January, also face a new deductible of $1,750 or more. Your old balance moves down their list. That is why Week 3 of the checklist focuses on patient balances before the reset.
💡 Not every plan resets on January 1. Some employer plans use a non-calendar plan year. Confirm each patient’s plan year during your eligibility check instead of assuming.
⏳ 3. Timely Filing & Appeal Deadlines to Check Right Now
Year-end is when timely filing losses peak, because services from late 2025 reach their Medicare 12-month limit. Example: a service on November 15, 2025 must be filed with Medicare by November 15, 2026. Commercial and Medicaid deadlines are often much shorter.
| Payer Type | Typical Initial Filing Limit | Year-End Action |
|---|---|---|
| Medicare (Original) | 12 months from date of service | File every late-2025 date of service now |
| Medicare redetermination (appeal) | 120 days from initial determination | Appeal recent denials before the window closes |
| Medicare Advantage | Set by plan contract | Check each plan; many are shorter than 12 months |
| Medicaid | Varies by state (often 90 days to 12 months) | Pull your state rules and MCO contracts |
| Commercial payers | Often 90–180 days (check your contract) | Prioritize the shortest deadlines first |
General guidance as of October 17, 2026 — always confirm deadlines in your payer contracts and current payer manuals. Look up any denial reason in our denial code library.

🧮 4. AR Aging Calculator: How Much Revenue Is at Risk?
Enter the dollars in each bucket of your aged AR report. The calculator uses typical collection rates by age to estimate what you can still expect to collect — and what is at risk.
Estimate only. Collection rates by age are common planning assumptions; your own history, payer mix and follow-up quality will differ. A focused cleanup raises collection on older buckets. For an exact analysis, request a free AR audit.

🎯 6. AR Triage Matrix: What to Work First
With limited time, work AR in this order. Deadline risk always comes first, then dollar value.
| Priority | Accounts | Why |
|---|---|---|
| 1 — Today | Claims within 30 days of timely filing or appeal deadline | Lost permanently if missed |
| 2 — This week | High-dollar claims (top 50 by balance) over 60 days | Biggest impact per hour of work |
| 3 — This week | Denials with a clear fix (eligibility, coding, missing info) | Fast to correct and resubmit |
| 4 — Next week | Underpayments against contracted rates | Money already owed under contract |
| 5 — Week 3 | 2026 patient balances, largest first | Harder to collect after January 1 |
| 6 — Week 4 | Small balances and long-aged accounts | Resolve per written policy |

💬 7. Patient Balance Playbook Before the Deductible Reset

⚖️ 8. Credit Balances, Refunds & Write-Offs
Year-end is also when compliance risk hides in your AR. Clean these up before you close the books:
| Item | What to Do | Watch Out For |
|---|---|---|
| Patient credit balances | Research, then refund or apply to another open balance with the patient’s consent | Unclaimed refunds may fall under state unclaimed property rules |
| Payer overpayments | Report and refund; for Medicare, identified overpayments generally must be returned within 60 days of identification | Holding known overpayments creates False Claims Act risk |
| Unapplied / unposted cash | Match every deposit to an ERA or patient payment | Inflates AR and hides real collection rate |
| Small-balance write-offs | Apply your written threshold after required statements | Inconsistent use can look like routine waivers |
| Bad debt | Write off only after documented collection effort | Hospitals: Medicare bad debt has specific effort rules |
| Contractual adjustments | Confirm they match contracted rates | Adjusting away underpayments loses real money |
General information, not legal advice — confirm requirements with your compliance officer. See our compliance services and data security in healthcare RCM.

🗓️ 10. Prepare for January: Stop AR from Rebuilding
A cleanup only lasts if January starts clean. Most new AR in Q1 comes from front-end problems: new insurance cards, changed plans and higher deductibles.
Re-verify every January visit
Run eligibility for all appointments in the first weeks of January and ask every patient for their current card.
AI eligibility check →Catch terminated policies
Detect plans that ended December 31 before claims go out.
Policy status verification →Estimate patient costs
Give estimates using the new deductible; provide good faith estimates to uninsured and self-pay patients.
Self-pay guide →Update codes & fees
Load 2027 CPT/HCPCS changes effective January 1 and the 2027 Medicare fee schedule once CMS finalizes it.
AI compliance checks →Renew authorizations
Re-authorize ongoing treatment whose approvals end December 31.
Prior auth guide →Lock in a weekly AR review
Thirty minutes every week keeps AR over 90 days under target all year.
KPI benchmarks →📊 11. KPIs to Measure Your Year-End AR Cleanup
