What Is CPT Code 11750? Modifiers, Reimbursement, and Denials in 2026

Quick Answers

CPT code 11750 is the procedure code for permanent removal of a nail and its underlying matrix, partial or complete, used when a problem nail such as an ingrown or deformed one is destroyed so it cannot grow back. Because it permanently removes the matrix, it is a distinct, higher level service than a simple nail avulsion, and it requires a digit modifier on every claim to identify the exact finger or toe treated.

Matrix removal is the key:
11750 applies only when the nail matrix is destroyed for permanent removal, which is what separates it from the simple avulsion code 11730, where the nail can still grow back.

Digit modifiers are mandatory:
Every 11750 claim must carry an anatomical modifier, a T modifier for toes or an F modifier for fingers, and the code is reported only once per digit.

It carries a 10-day global period:
Routine follow up care within 10 days is bundled into the payment, so it cannot be billed separately unless an unrelated service is documented.

What CPT 11750 Actually Covers

CPT 11750 reports the permanent removal of a nail and its matrix, whether partial or complete. The distinguishing feature is destruction of the matrix, the tissue under the nail that generates new growth. A provider lifts and removes the nail plate, then destroys the matrix by chemical means such as phenol, by electrocautery, or with a laser, so the treated portion of the nail cannot return. Per the Medicare article on the surgical treatment of nails (A52998), a single unit of 11750 represents all work performed on that one nail for that date of service. When both the lateral and the medial borders of the same nail are treated, that still counts as one procedure and one unit, not two. That is the single most useful fact to hold onto, because trying to bill each border separately is a fast route to a denial.

There is also a history worth knowing. An older companion code, 11752, which covered matrix excision together with amputation of the tuft of the distal phalanx, was deleted. When a bone procedure is genuinely part of the surgery today, the work is reported as 11750 for the nail and matrix plus a separate bone code such as 28124, rather than one combined code.

In our experience matching providers with billing partners, the confusion almost always starts at this definition. A note that simply says the nail was removed is not enough to support 11750. The record has to show that the matrix itself was destroyed for permanent removal. Without that language, the correct code is the simpler nail avulsion, code 11730, and billing 11750 instead invites an audit.

When 11750 Is the Right Code

11750 is appropriate when conservative care has failed and the clinical goal is to stop a problem nail from returning. The classic case is a recurrent ingrown toenail that keeps getting infected, where the provider performs a matrixectomy on the affected border to end the cycle. It also applies to severely deformed or chronically diseased nails where permanent removal is the treatment plan rather than a first response.

Medical necessity is carried by the diagnosis code, and payers scrutinize the pairing closely. Common supporting ICD-10 codes include L60.0 for an ingrowing nail, L60.2 for onychogryphosis, which is a thickened, claw like nail, L60.3 for nail dystrophy, and B35.1 for tinea unguium, the fungal nail infection also called onychomycosis. B35.1 is valid through September 30, 2026 for current claims. The most common issue we see providers run into is a mismatch between the procedure and the diagnosis, where the operative note describes permanent matrix destruction but the linked diagnosis does not clearly justify it. Clean documentation and a supported diagnosis are what move an 11750 claim from pended to paid.

What is the difference between CPT 11750 and 11730?

The difference is the matrix. CPT 11750 permanently removes the nail and destroys the matrix so the nail cannot grow back, while CPT 11730 is a simple avulsion that lifts off the nail plate but leaves the matrix intact, so the nail regrows over time. Using 11730 when the matrix was destroyed underbills the work, and using 11750 when it was not invites a denial.

This one distinction drives most nail coding errors. 11730 is a temporary removal and a lower value service. 11750 is a permanent removal and a higher value service. A third code, 11765, covers a wedge excision of the skin of the nail fold and is a different procedure again. The three should never be reported together for the same digit on the same date of service, since each represents the complete service for that nail. The comparison below lays out how they separate.

Factor	CPT 11750	CPT 11730	CPT 11765
What is removed	Nail plus matrix, permanent	Nail plate only, temporary	Wedge of nail fold skin
Matrix destroyed	Yes	No	No
Nail regrows	No	Yes	Yes
Typical use	Recurrent ingrown or deformed nail	Ingrown nail, trauma, infection	Ingrown toenail, soft tissue
Digit modifier required	Yes	Yes	Yes

Modifiers That 11750 Requires

Because 11750 has to identify exactly which digit was treated, it cannot be billed without an anatomical modifier. Payers deny the claim outright when the digit modifier is missing. These are the modifiers that matter most for this code:

• T modifiers (T1 through T9 and TA) identify the specific toe treated, and TA is the left great toe.
• F modifiers (FA and F1 through F9) identify the specific finger when the procedure is performed on a hand.
• Modifier 50 reports a bilateral procedure when the same nail is treated on both the left and right foot.
• Modifier 59 or the X modifiers mark 11750 as a distinct service when it is performed on a separate digit alongside another procedure.
• Modifier LT or RT indicates the left or right side when a payer requires side identification instead of a T modifier.
• Modifier KX signals a medically necessary repeat excision on the same toe, which payers otherwise deny as a duplicate.
• Modifier 24 reports an unrelated evaluation and management visit during the 10-day global period.

When 11750 is performed on two different toes in the same session, report one unit per toe with the matching digit modifier, for example 11750 TA and 11750 T5, rather than stacking multiple units on a single line. For a fuller reference on which modifiers pair with which podiatry codes, the podiatry billing and coding cheat sheet is a useful desk companion.

How is CPT 11750 reimbursed in 2026?

CPT 11750 is paid under the Medicare Physician Fee Schedule and carries a 10-day global period, so routine post procedure visits are bundled into the payment. The exact allowed amount is set by relative value units and adjusted by locality, so it varies by Medicare Administrative Contractor and by whether the service is performed in an office or a facility.

Because the rate is locality adjusted, there is no single national number a practice can safely rely on. The accurate way to confirm a rate is to pull the code in the CMS Physician Fee Schedule Look Up Tool for your locality and year, or check your MAC portal directly. Contractors such as Novitas and First Coast Service Options publish their own coverage articles for nail procedures, and their rules on repeat excisions have shifted in recent years, including guidance to append modifier KX and let a repeat be considered rather than resubmitting for redetermination. Across the billing companies we vet, the strong ones always confirm the current year allowable and the payer specific policy before posting, rather than assuming last year’s rate still holds.

Common 11750 Denials and How to Prevent Them

Every podiatry practice runs into the same handful of 11750 denials. Providers often come to us after watching these claims pend or reject for reasons that trace back to documentation and coding rather than to the care itself. Fixing them is usually a matter of process, not effort:

• Missing digit modifier. The claim does not identify the toe or finger. Fix: append the correct T or F modifier to every 11750 line before submission.
• Wrong code for the work. 11750 is billed when only a simple avulsion was done, or 11730 is billed when the matrix was actually destroyed. Fix: match the code to the operative note and confirm whether the matrix was permanently destroyed.
• Repeat excision on the same digit. A second 11750 on a toe already treated is denied as a duplicate. Fix: append modifier KX and document why the repeat is medically necessary.
• Unsupported diagnosis. The linked ICD-10 code does not justify permanent removal. Fix: pair 11750 with a supporting diagnosis such as L60.0, L60.2, L60.3, or B35.1.
• Billing both borders separately. Two units are reported for the medial and lateral sides of one nail. Fix: report one unit of 11750 per nail regardless of how many borders were treated.
• Global period conflicts. A follow up visit inside 10 days is billed separately. Fix: bundle routine post op care and use modifier 24 only for a genuinely unrelated visit.

Catching these before submission rather than after rejection is where a dependable podiatry billing partner earns its keep, since each reworked claim costs staff time that a busy schedule cannot spare.

Documentation That Supports 11750

An 11750 claim is only as strong as the operative note behind it. To survive a payer review, the record should state the specific nail and digit treated, the clinical reason for permanent removal such as a recurrent ingrown nail, and the fact that the matrix was destroyed along with the method used, whether phenol, electrocautery, or laser. It should also confirm that conservative measures were tried or were not appropriate, since payers expect permanent removal to be a considered step. One question we hear constantly from practice managers is why a clean looking claim still got denied, and the answer is almost always that the note described removing the nail without ever documenting the matrix destruction that defines the code. If the words matrix and permanent are not in the note, the code is exposed.
