How to Read an Accounts Receivable Aging Report in an Optometry Practice

A full appointment schedule does not always mean every visit has been paid. An insurance claim may still be awaiting a response, a payment may not have been matched to the account, or a patient balance may need a different check. For optometry practice owners, managers, and billing teams, an accounts receivable (A/R) aging report shows how long open balances have been outstanding under the report’s settings. It does not explain why they remain open. This guide shows how to read the buckets, interpret a sample report, separate payer from patient follow-up, and give each selected balance a clear next action.

What do the A/R aging buckets mean?

Aging reports commonly group open balances into intervals such as 0–30, 31–60, 61–90, and 91 or more days. The intervals show how long a balance has been outstanding according to the report’s selected aging calculation. The exact boundaries and the date used to calculate age vary by system and configuration.

An older balance may deserve earlier investigation, but age alone does not establish that it is overdue, incorrect, or uncollectible. A newer balance can still need attention. The claim or account history supplies the context for deciding what to check and who should handle it.

Check the report settings first

Before comparing totals or assigning work, note the as-of date, the date the system uses to age a balance, the bucket boundaries, and filters for location, provider, payer, or account status. Check whether the report is a summary or account-level detail and whether it includes credits, estimates, unapplied payments, or only billed balances.

Report definitions differ by product. For example, Therabill’s balance-aging guide describes insurance aging based on date billed, while Open Dental’s A/R report manual documents its own as-of date, filters, and treatment of negative balances and estimates. These are system-specific examples. Use your own practice system’s report description when interpreting its columns.

If you review the report weekly or monthly, keep its date basis, filters, and included balance types consistent. Otherwise, a shift between buckets may reflect a changed setup rather than a change in follow-up.

Read the totals, then inspect individual balances

Start with the total row to see how much open A/R falls into each age bucket. Then read across the payer or patient row to see who is associated with the balance and where it sits. The example below represents a fictional optometry practice as of September 30, 2026. The amounts and bucket labels are illustrative; use the labels in your own report.

To reuse this as a spreadsheet summary, copy the columns, replace the example amounts with your report totals, and calculate each bucket’s share as bucket total ÷ total open A/R. Keep the bucket labels and aging basis from your own report.

The rows and columns reconcile: payer balances total $17,600, patient balances total $6,900, and together they equal $24,500. The 91+ bucket contains $5,900, or $5,900 ÷ $24,500 = 24.1% of the example’s total. The 61–90 and 91+ buckets together contain $10,300, or 42.0%.

In practical terms, 42% of this example’s A/R is more than 60 days old. That points to records worth examining; it does not reveal why they remain open. Older payer claims may call for a status or remittance check, while patient balances may require verification of responsibility, payment allocation, or statement activity. Read down the total column for the overall age distribution, then open the relevant claim or account to establish what happened. These figures describe one fictional practice, not a benchmark, write-off estimate, or proof that a balance is uncollectible. For a practical follow-up framework, see the patient balance collection process.

Separate payer work from patient work

Payer and patient balances call for different checks. For a payer balance, verify whether the claim was sent and accepted, review the latest payer status, and look for a remittance or adjustment. If the payer adjudicated the claim, compare the remittance with the posted payment and remaining account balance. A balance may reflect a submission issue, an unresolved response, a posting mismatch, or another cause; the aging bucket does not identify which one.

Optometry practices may handle both medical insurance claims and vision-plan claims, but their payer mix and arrangements vary. Coverage and payment rules can differ by service and plan; for example, CMS guidance distinguishes Original Medicare coverage for certain eye-related medical services from routine vision services, while vision-plan benefits are defined by the applicable plan. Follow up using the payer, claim type, current status, remittance, and relevant plan terms for that specific balance.

On the patient side, verify the amount in the account record and the applicable remittance before deciding whether the next step is a statement, a corrected allocation, or further review. In Medicare remittance advice, CMS explains that group code PR assigns financial responsibility to the patient and CO assigns it to the provider. This is a Medicare example, not a rule for other payers or, by itself, authorization to bill. Check the actual remittance, contract, and practice policy.

Turn the report into a follow-up worklist

A useful worklist makes the next check visible and assigns someone to own it. The three fictional examples show how different balances lead to different checks. Replace the sample labels with internal account or claim references, and follow your approved process for handling identifiers.
