Underpayment recovery
on claims marked paid
Your margin isn't lost at the denial — it's shaved at the deposit.
Ask a surgical group where revenue-cycle pain lives and you'll hear denials, A/R days, prior auth. Those are loud. They aren't what costs the most. The most expensive problem clears cleanly, posts as paid, and quietly settles a few points under your contracted rate.
Across the 38 orthopaedic revenue cycles we've analyzed, an average of 4.2–7.3% of gross revenue is withheld this way. On a $12M practice, that's $504K–$876K a year — and it compounds over every payer-contract cycle.

The 4.2–7.3% range reflects OneMed's analysis of 38 orthopaedic revenue cycles; the dollar figures apply that range to a $12M example practice. Your actual exposure depends on payer mix, case mix, and documentation.
Where surgical dollars quietly go missing.
Ortho billing is a minefield of global periods, implant carve-outs, and modifier rules. High-volume payer systems lean on that complexity, and the shortfalls hide on claims your team already booked as paid.
Global-period Modifier 24 erasure
A post-op patient returns within the 90-day global period for an unrelated problem — say, the opposite shoulder. The E/M is billed with Modifier 24, but payer rules see an E/M inside the global window and pay it at $0 as "included in the global package."
Implant carve-out failure
High-value implants (reverse shoulder components, revision knee hardware, biologic anchors) are separately reimbursable under contractual carve-outs. Payers routinely pay the flat APC or DRG rate instead, bundling the implant cost into the base procedure.
MPPR misapplication
Under the Multiple Procedure Payment Reduction, the primary procedure pays at 100% and secondaries at 50% — but some ortho combinations are exempt and certain add-ons should pay at 100%. Payers sometimes reduce the primary instead of the secondary, or apply MPPR to exempt procedures.
Bilateral modifier shortfall
Bilateral procedures — bilateral knee arthroscopy, carpal tunnel, trigger finger — should pay at 150% of the unilateral rate with Modifier 50. Payers frequently pay them at the unilateral rate, silently dropping the additional 50%.
E/M level downgrade
High-complexity ortho visits — new injuries, post-op complications, surgical decision-making — support 99214 / 99204, but payers routinely reprice them to 99213 / 99203, claiming the medical decision making didn't meet the threshold.
The 150% rule is public. So is the shortfall.
Take the bilateral shortfall. Under standard payment rules, a bilateral procedure billed with Modifier 50 should pay at 150% of the unilateral rate. When a payer pays it flat — at 100% — that missing 50% is pure margin, gone.
The rule is public and you can check it against your own contracts. Across a few hundred bilateral cases a year, a flat-rate payment on even a third of them is a six-figure leak on one trap alone.

The 150% bilateral (Modifier 50) rule is standard; the $1,200 is an illustrative example — confirm against your contracted rates. Actual exposure depends on your bilateral volume and payer.
Your team isn't the problem — the bandwidth is
It isn't effort. No billing team can hand-check hundreds of surgical claims against contract terms, case by case, every month.
The "paid means paid" blind spot
Attention goes to $0 rejections. When a claim says paid, the file closes — no one re-checks 300 joint replacements against your payer contracts for silent carve-out failures.
No contract-level verification
Comparing each paid APC rate against your specific carve-out terms, case by case, isn't realistic for a standard billing team.
No global-period tracking
When a patient returns six weeks post-op, there's no system flagging whether the visit is unrelated and whether Modifier 24 applies.
We recover what your contracts actually owe you.
Certified orthopaedic coders, working inside your current system. No EHR swap, no workflow change — just people who read the operative note, where payer rules only ever read the remit.
ClearView operational visibility
Our ClearView dashboard gives leadership real-time visibility into the revenue cycle — flagging when a joint replacement paid at $4,200 against a $6,800 carve-out, or a bilateral case paid at the unilateral rate — without changing how your staff logs in.
Expert clinical chart audit
Flagged claims route to our AAPC-certified orthopaedic coders, who work inside your system to read the operative note, verify the implants and bilateral procedures, and confirm unrelated post-op visits.
Targeted clinical appeal
We draft a documentation-backed appeal — the exact operative and contractual language that supports the correct payment.
Payer pattern mapping
We track which payers fail to apply your carve-outs or misapply MPPR, and pursue systematic corrections and contract fixes — not just one claim at a time.

Of that $4.41M, here's where it had been hiding. The highest-cost surgical work gets underpaid the most — the leak is the baseline, not the exception.
| Underpayment pattern | Share of recovered value |
|---|---|
| Implant carve-out failures | 38% |
| MPPR misapplications | 24% |
| E/M level downgrades | 16% |
| Bilateral modifier shortfalls | 14% |
