Physical therapy practices operate differently from most service businesses because the patient who receives care usually isn’t the one paying for it. Insurance companies pay the bulk of revenue, and that changes everything about how the books need to work.

When a PT treats a patient, the practice bills the insurance company. But insurance rarely pays the full billed amount. They pay according to contracted rates, apply deductibles, and sometimes deny claims entirely. The books have to track what was billed, what was paid, what was adjusted off as a contractual write-off, and what remains as patient responsibility. Physical therapy practices that don’t track these pieces separately end up guessing at their true revenue.

Accounts receivable becomes the center of the financial picture. At any given time, a PT practice might have tens of thousands of dollars in outstanding claims waiting for payment. The books need to age these receivables by payer and by date so you can see which claims are current, which are getting stale, and which need follow-up before they age out.

Matching payments to claims is another layer of complexity. When an insurance payment arrives, it often covers multiple dates of service and multiple patients. Each payment has to be matched to the original claim and any remaining patient responsibility posted correctly. If this isn’t done right, you lose visibility into what’s actually owed and your collection rates by payer become meaningless.

Patient copays and deductibles add another revenue stream to track. Some patients pay at the time of service, others get billed later. Self-pay patients pay entirely out of pocket. Each needs separate tracking because collection rates and timing differ significantly from insurance payments.

Write-offs matter too. Contractual adjustments, meaning the difference between what you bill and what insurance allows, aren’t bad debt. They’re expected. But you need to separate contractual write-offs from actual uncollectible accounts to understand your true revenue. If these get lumped together, you can’t tell whether your payer contracts are reasonable or your collection process is failing.

The end result is that cash on hand doesn’t tell you much about financial health. A PT practice could show $100,000 in accounts receivable, but if half of it is over 90 days old and much of it will be written off, the actual collectible amount is far less. Good bookkeeping services surface this reality so the owner can make decisions based on what they’ll actually collect, not what they billed.
