Physical therapy billing services
When a payer underpays against your contract, the gap often posts as a CO-45 contractual adjustment. The claim shows as paid and looks like a normal write-down, so nobody looks at it again.
Twenty minutes. If your current billing is in good shape, we will tell you that.
Pull the last ninety days of remittances and filter for CO-45 adjustments. For your five most billed codes, compare what was paid against your contracted rate.

The basics, since you will check anyway
Your lead biller is US based and has 8 to 15 years of billing experience, with a support team behind them. Invoisync has been doing this for 9 years.
Most of that comes from work nobody was doing: claims never submitted, denials never worked, and payments under the contracted rate.
We sign a Business Associate Agreement at onboarding. We work inside the EHR you already use, with nothing to install, and your data stays yours.
Contract renegotiation is an additional service we provide to new clients at no charge, as a way to raise what you are paid for the work you already do.
Each one leaves your reports looking healthy.
The claim came back paid, below the contracted rate, and the difference was adjusted off as contractual.
The visit happened and the note exists. The charge was never built, so nothing came back denied.
Your payer contract renews every year at the rate you agreed to years ago.
A client kept running long on follow-up visits. The schedule said one thing, the claim numbers said another, and the two never lined up. Our team asked about the gap.
The practice had been providing a service they did not know was covered. It was documented in the notes every time. It had never been submitted. We filed retroactively and it kept paying going forward. The level of care they wanted to provide stopped being a time cost, and growth became an option.
Step one
You check it yourself. The self-check above takes one report and about ten minutes. You do not need us for that part and you do not have to tell us what you found.
Step two
Twenty minutes on the phone. You tell us what you found and what you run on. We tell you what we would expect to find underneath it and what it takes to fix.
Step three
If you move, payer contract renegotiation is part of onboarding, at no separate fee. Rates set back when the practice was smaller are usually the second thing we find.
Not one of these requires a meeting, and how long the answers take is the answer.
How much did we write off as CO-45 last quarter, and how much of it was below our contracted rate?
When were our payer contracts last renegotiated?
Of the denials from the last ninety days, how many have had no activity in the last thirty?
How many days from visit to claim, on average?
Which payers changed their therapy rules this year, and what did we change?
Can you hand me a list of every open denial and what has been done to it?
