For medical practices, insurance reimbursements don’t arrive in neat, predictable amounts. You bill one thing, the insurer pays something less, and there’s a contractual adjustment in between. Tracking this properly means understanding the difference between what you charged, what you expected, and what you actually received.

The starting point is your practice management or billing software. When you submit a claim, that creates an accounts receivable entry. The patient owes you money, or rather their insurance does. Most practices use software like Kareo, AdvancedMD, or Athenahealth for this. Your accounting software, usually QuickBooks, needs to reflect these amounts accurately.

When the insurance company processes the claim, they send an Explanation of Benefits. This document shows what you billed, what the insurance allowed, what they paid, and what the patient owes. Recording this correctly in your books requires separating the payment from the adjustment.

Here’s how the entries typically work. Say you billed $200 for a service. The insurance allowed rate is $150, they paid $120, and the patient owes $30. You record the $120 payment received, the $30 as patient A/R, and the $50 difference as a contractual adjustment. That $50 isn’t a loss or a write-off in the traditional sense. It’s the difference between your fee schedule and what you contractually agreed to accept from that payer.

Contractual adjustments should have their own account in your chart of accounts. Don’t lump them with bad debt or general write-offs. Bad debt is money you expected to collect but couldn’t. Contractual adjustments are expected reductions based on your insurance contracts. Mixing them gives you a distorted picture of your practice’s financial health and makes it harder for a small business accountant in the San Gabriel Valley to help you analyze your revenue.

Track reimbursements by payer. Different insurers pay different rates for the same service. Over time, you’ll see which payers reimburse well and which ones drag down your revenue. This data helps when renegotiating contracts or deciding which insurance panels to stay on.

Reconcile your billing software to your accounting software monthly. They should agree on total A/R, total payments received, and total adjustments. When they don’t match, something got recorded wrong. Catching these discrepancies early prevents bigger problems at year end.

Run aging reports weekly or at least every two weeks. Claims sitting unpaid for 30, 60, or 90 days need follow-up. Insurance companies deny claims or lose them. Without active tracking, you’ll miss reimbursements you’re entitled to. Many practices leave thousands on the table simply because nobody followed up on unpaid claims.

Patient responsibility portions need tracking too. After insurance pays their part, patients owe co-pays, deductibles, or coinsurance. These amounts should appear as patient A/R in your books. If you’re not billing patients for their portion or following up on unpaid balances, you’re losing revenue.

The complexity of medical practice billing and reimbursement is why most practices need either dedicated staff or outside help. A bookkeeper who understands the nuances of EOBs, contractual adjustments, and payer tracking can set up systems that give you real visibility into your revenue cycle.

If your books don’t clearly show what you’re owed, what you collected, and what you adjusted off, you’re flying blind. Clean financial records tell you whether your practice is actually profitable or just busy.
