End-of-Month Reconciliation for Wound Care Practices

Month-end reconciliation is the financial checkpoint that separates wound care practices running on real data from those running on assumptions. Every practice has a general sense of how the month went -- busy, slow, somewhere in between. Reconciliation replaces that sense with numbers: charges captured versus visits rendered, claims submitted versus claims paid, supply costs versus supply consumption, and aging balances that need attention before they become write-offs.

Most wound care practices skip formal month-end reconciliation or reduce it to "check the bank account." The result is revenue leakage that accumulates invisibly -- missed charges from two weeks ago, denied claims that were never reworked, supply costs that crept up 12 percent without anyone noticing. By the time these issues surface, they have compounded.

This guide covers a structured monthly close process designed for wound care practices. For the KPIs that drive ongoing revenue cycle monitoring, Wound Care Revenue Cycle KPIs covers the metrics framework.

Charge Reconciliation: Every Visit Must Have a Charge

The first reconciliation step is confirming that every patient visit in the month generated at least one billable charge. This sounds basic. In practice, charge leakage is one of the most common revenue problems in wound care.

The Visit-to-Charge Audit

Pull two reports: your visit log (every patient encounter for the month) and your charge log (every billable charge submitted). Compare them side by side.

Every visit should have at least one charge. A wound care visit that involved debridement, a dressing change, or an E/M service generated billable work. If a visit appears on the visit log without a corresponding charge, investigate. Common causes: the clinician deferred documentation and forgot the charge, the charge was entered but not submitted, or the encounter was saved as a draft and never finalized.

Check for under-coding. A visit note documenting selective debridement of three wounds with distinct tissue removal should generate multiple charge lines -- 97597 for the first wound, 97598 for additional areas, plus modifiers for wound-specific coding. If the charge only shows one 97597, revenue was left behind. This is not upcoding -- it is capturing what was actually performed and documented.

Verify modifier accuracy. Wound-specific modifiers (59, XE, XS for distinct anatomical sites) must match the wound locations documented in the note. A claim with modifier 59 on a second debridement but wound locations that do not justify distinct-site coding will be denied or recouped on audit.

Accounts Receivable Review

Accounts receivable (AR) aging tells you how much money is owed to your practice and how long it has been outstanding. Month-end is when you identify claims that are aging into danger zones.

AR Aging Buckets

0 to 30 days. These are current claims. Verify they have been submitted to the correct payer and are in processing. No action needed unless a claim shows a rejection or pending status that requires intervention.

31 to 60 days. Check for claims that have not adjudicated. Contact the payer on any claim over 45 days without a response. Common causes: claim not received (resubmit), claim pended for additional information (respond immediately), or claim processing backlog at the payer (document the follow-up).

61 to 90 days. This is the action zone. Every claim in this bucket should have an assigned follow-up with a specific next step documented. Claims that sit in this range without active pursuit have a declining probability of collection with each passing week.

Over 90 days. Claims over 90 days are at serious risk. Some payers have timely filing limits that start at 90 days from date of service. If a clean claim has not been submitted within the payer's filing window, the revenue is permanently lost. Review each claim individually and determine whether appeal, resubmission, or write-off is appropriate.

Denial Rework

Pull all denied claims for the month. Categorize denials by type: eligibility/coverage denials, medical necessity denials, coding denials, and timely filing denials.

Eligibility denials usually mean the patient's coverage was not active on the date of service or the wrong payer was billed. Verify eligibility and resubmit to the correct payer.

Medical necessity denials mean the documentation did not support the service billed. Review the note for missing elements -- wound measurements, tissue type, treatment rationale, healing trajectory -- and resubmit with corrected or supplemental documentation.

Coding denials mean the CPT or ICD-10 codes did not match payer requirements. Common in wound care: wrong modifier, unlisted diagnosis code, or procedure code that does not match the documented wound depth.

Supply Inventory Count

Month-end is when you reconcile what you bought against what you used and what remains on the shelf.

Physical Count

Count every dressing, topical product, and supply item in stock. Compare the count to your beginning-of-month inventory plus purchases minus documented usage. The difference is your shrinkage -- a combination of untracked usage, waste, and potential misallocation.

Target shrinkage below 5 percent. A wound care practice with $6,000 in monthly supply purchases should not have more than $300 in unaccounted shrinkage. If shrinkage exceeds 5 percent, investigate by category to find the source.

Expiration Check

Pull every item expiring within the next 60 days. Determine whether current patient census will consume it. Reallocate, return to vendor if within return policy, or flag for accelerated use. Products that expire without being used are pure loss.

Cost Per Visit Calculation

Divide total supply cost for the month by total patient visits. This gives you a supply cost-per-visit metric that should remain relatively stable month to month. If cost per visit spikes, investigate -- it usually means a high-cost product (skin substitute, collagen, NPWT supplies) was used more than expected, or waste increased.

Monthly Metric Review

Month-end is when practice performance metrics get a formal review. These numbers drive decisions for the following month.

Core Metrics

Visits per clinician per day. Average across the month. Trending up means efficiency gains or increased demand. Trending down may indicate scheduling gaps, cancellations, or documentation backlog slowing visit throughput.

Collection rate. Total payments received divided by total charges submitted. A healthy wound care practice should target 85 to 95 percent collection on clean claims. Below 80 percent indicates systematic billing problems.

Days in AR. Average number of days between charge submission and payment receipt. Target 30 to 45 days. Above 50 days means claims are stuck in the pipeline and need intervention.

Denial rate. Total denied claims divided by total claims submitted. Below 5 percent is strong. Above 10 percent requires root cause analysis by denial category.

Patient census. Active patients at month end versus beginning of month. Net growth or decline tells you whether your referral pipeline is keeping pace with discharges and completions.

Key Takeaways

Compare your monthly visit log to your charge log line by line -- every documented visit should have at least one submitted charge, and charge leakage is one of the most common revenue problems in wound care.
Review AR aging buckets monthly with specific follow-up actions for every claim over 60 days, as collection probability declines sharply after 90 days and timely filing limits can make recovery impossible.
Conduct a physical supply inventory count at month end, targeting shrinkage below 5 percent of total supply cost, and check for items expiring within 60 days.
Track five core metrics each month: visits per clinician per day, collection rate, days in AR, denial rate, and active patient census to identify trends before they become problems.
