CPT Code for Distal Biceps Tendon Repair

If you are reading this, chances are you have a patient with a torn distal biceps tendon, or you are the medical coder trying to make sense of the operative report. You are not alone. Distal biceps ruptures are relatively uncommon compared to proximal ruptures, but when they happen, the surgical repair can be technically tricky.

The good news is that the coding landscape for this procedure is more stable than it used to be. However, there is still plenty of confusion. Does the repair involve a suture anchor? Was it an acute tear or a chronic one? Did the surgeon use an endoscopic technique?

This guide will walk you through everything you need to know about the cpt code for distal biceps tendon repair. We will keep the language simple, avoid unnecessary medical jargon, and focus on what actually works in the real world of billing and reimbursement.

Let us start with the short answer, and then we will dive into the details.

The Short Answer: Which Code Do You Use?

For the majority of distal biceps tendon repairs performed today, you will use CPT 24342. However, context matters.

• CPT 24341: Repair of the biceps tendon, at the elbow; distal, with or without suture anchor.

• CPT 24342: Repair of the biceps tendon, at the elbow; distal, with a single incision technique (this often includes tenodesis or reattachment).

Important Note for Readers: Many coders and surgeons get confused between these two codes. The key difference is not always the device (anchor vs. no anchor) but the complexity of the exposure and the chronicity of the tear. Do not guess. Read the operative note carefully.

Why the Correct CPT Code Matters for Your Practice

Using the wrong code does two things. First, it delays payment. Second, it puts you at risk for an audit. Insurance companies look closely at upper extremity repairs because they are frequently miscoded.

When you submit a claim for a distal biceps repair, you are telling a story. The CPT code is the title of that story. If the title does not match the content (the operative report), the claim will be rejected or downcoded.

A downcoded claim means you get paid less. For example, if you bill for a complex repair but the documentation only supports a simple repair, you lose revenue. On the other hand, if you bill for a simple repair when the surgeon performed a complex revision, you are leaving money on the table.

Accuracy protects your revenue and your reputation.

Anatomy Primer: Understanding the Distal Biceps Tendon

To code this correctly, you need to understand where the tendon is and what it does. The biceps muscle has two proximal tendons (the long head and the short head) and one distal tendon. The distal tendon attaches to the radial tuberosity, which is a bony bump on the radius bone in the forearm.

When this tendon tears, the patient usually feels a sudden pop in the elbow. They may have a “Popeye” deformity, where the muscle bunches up near the shoulder. The patient loses significant supination strength (turning the palm up) and some elbow flexion strength.

Surgery aims to reattach the tendon back to the radial tuberosity. The way the surgeon does this determines the CPT code.

The Two Main CPT Codes for Distal Biceps Repair

Let us break down the two primary codes side by side. This comparison table will help you see the differences at a glance.

CPT 24341: The Standard Acute Repair

Think of CPT 24341 as the workhorse code for a straightforward, first-time repair. The surgeon makes an incision in the front of the elbow (anterior approach). They locate the torn tendon end, clear out scar tissue if necessary, and then reattach the tendon to the radial tuberosity.

The code description says “with or without suture anchor.” This is important. Some surgeons drill bone tunnels and suture the tendon through them. Others use a single suture anchor. Both methods fall under 24341, as long as the procedure is a relatively uncomplicated reattachment.

When to use 24341:

• The tear is acute (less than 4 weeks old).

• The tendon has not retracted more than a few centimeters.

• The surgeon does not need to perform a graft or a complex reconstruction.

CPT 24342: The Single Incision Technique (Often More Complex)

CPT 24342 is a bit of a chameleon. The official descriptor emphasizes a “single incision technique.” Historically, surgeons used a two-incision approach to avoid injuring the posterior interosseous nerve (PIN). Today, most surgeons use a single anterior incision with improved safety.

So why would you use 24342 instead of 24341? The answer usually comes down to chronicity and retraction.

When a distal biceps tendon tears and is not repaired immediately, it shrinks. The muscle shortens. The tendon retracts up the arm. Reattaching it becomes much harder. The surgeon may need to perform a tenodesis (attaching the tendon to a different spot) or use a graft to bridge a gap.

Real-world tip: Many coders report that 24342 is the correct code for a “distal biceps repair with tendon graft” or a “delayed repair with significant mobilization.” If the operative report mentions “extensive scar excision,” “tendon lengthening,” or “significant retraction,” lean toward 24342.

When to Use Modifiers with Distal Biceps Repair Codes

Sometimes the basic CPT code is not enough. You may need a modifier to tell the full story.

Modifier 50: Bilateral Procedure

Distal biceps ruptures in both elbows are extremely rare, but they can happen, usually in weightlifters or manual laborers. If the surgeon repairs both elbows during the same surgical session, you append Modifier 50 to the CPT code.

Example: 24342-50

Modifier 58: Staged or Related Procedure

If the patient had a previous distal biceps repair that failed, and the surgeon goes back to the operating room for a revision during the postoperative period, you may use Modifier 58. This tells the payer that the second procedure was planned or was more extensive than the first.

Modifier 78: Return to the OR for a Complication

This is less common but happens. If the patient develops a hematoma or a rerupture within the global period and requires a return to the operating room, you use Modifier 78. This modifier reduces the payment, but it is better than no payment.

Partial Ruptures vs. Complete Ruptures

Here is a question that comes up frequently: Does the CPT code change for a partial distal biceps tear?

The short answer is no. CPT does not distinguish between partial and complete ruptures for these codes. Both 24341 and 24342 can apply to partial tears if the surgeon performs a repair.

However, you need to read the operative note carefully. If the surgeon only performs a debridement of a partial tear without reattachment, that is a different code entirely (CPT 24340, tenotomy or debridement). Do not confuse the two.

A quick checklist for coders:

• Does the note say “reattached,” “repaired,” or “fixed to bone”? → Use 24341 or 24342.

• Does the note say “debrided” or “released” without fixation? → Use 24340 (tenotomy/debridement).

Endoscopic Distal Biceps Repair: Does It Have a Different Code?

Minimally invasive techniques are becoming more popular. Some surgeons now perform endoscopic distal biceps repairs using small incisions and a camera.

Here is the frustrating truth: There is no specific CPT code for endoscopic distal biceps repair.

You must use the code that describes the procedure performed, not the approach. Therefore, an endoscopic repair is still coded as 24341 or 24342 based on the complexity and technique (single incision vs. other).

Warning: Some coders try to use unlisted CPT codes (such as 29999 for unlisted arthroscopic procedure) for endoscopic repairs. This is generally a bad idea. Unlisted codes require a cover letter, often get denied, and reimburse unpredictably. Stick with 24341 or 24342 unless the payer has a specific local coverage determination stating otherwise.

Chronic Tears and the Use of Allograft (Tendon Graft)

Now we enter the gray zone. What happens when a patient shows up six months after a distal biceps rupture? The tendon has retracted, scarred down, and shortened. The surgeon cannot simply pull it back to the radial tuberosity. They need a graft.

Common graft sources include:

• Autograft (from the patient’s own semitendinosus or gracilis tendon)

• Allograft (cadaver tendon)

The CPT code for a distal biceps repair with graft is not explicitly listed. However, most coding experts agree that CPT 24342 is the appropriate code for this scenario. The graft is considered part of the complex reconstruction.

If the graft harvest requires a separate, significant incision (for example, harvesting the semitendinosus from the knee), you may add CPT 20924 (tendon graft harvest, each tendon). But check your payer policies. Some bundles this into the primary procedure.

A Realistic Billing Scenario

Let me paint you a picture. This is a typical chart you might see on a Monday morning.

Operative Note Summary:
Patient is a 42-year-old male, construction worker, who felt a pop in his right elbow while lifting a heavy pipe three days ago. MRI shows a complete distal biceps tendon rupture with 3 cm retraction. Surgeon performs an anterior single incision approach. The tendon end is identified, debrided, and reattached to the radial tuberosity using two suture anchors.

What is the correct CPT code?

Most coders would choose 24341. The repair is acute, uncomplicated, and uses suture anchors. The code explicitly allows for anchors. It is clean and straightforward.

Now change the scenario:
Same patient, but the injury happened eight months ago. The patient tried conservative treatment but lost supination strength. The surgeon finds the tendon severely retracted, requires extensive mobilization, and uses a gracilis allograft to bridge a 4 cm gap.

Now the correct code is 24342. The complexity is higher. The work is greater. Document the graft.

Common Denials and How to Fight Them

Even when you use the correct CPT code, payers may deny your claim. Here are the most common reasons.

Denial: “Procedure not medically necessary”

This often happens when the documentation does not show functional deficit. Make sure the operative report mentions:

• Loss of supination strength

• Loss of elbow flexion strength

• Inability to perform job duties or sports

• Failure of conservative care (for chronic tears)

Denial: “Bundled service”

Sometimes payers try to bundle the repair code with the closure or the diagnostic arthroscopy. Make sure you did not bill for an unnecessary diagnostic scope. If the surgeon performed a diagnostic elbow arthroscopy before the open repair, you may need Modifier 59 (distinct procedural service) on the arthroscopy code (29830) to show it was separate.

Denial: “Missing documentation”

This is the easiest one to fix. Always submit the operative report with the claim for distal biceps repairs. These are not routine office visits. Payers want to see the details.

How to Document Like a Pro (For Surgeons)

If you are a surgeon reading this, you have the power to make your coder’s life much easier. A few sentences in your dictation can mean the difference between a paid claim and a denied one.

Here is a template you can adapt:

“This is a [acute/chronic] distal biceps tendon rupture of the [left/right] elbow. The tendon retracted approximately [X] cm from the radial tuberosity. Using a [single anterior] incision, I identified the tendon stump, mobilized it by excising [adhesions/scar tissue], and repaired it to the radial tuberosity using [suture anchors/bone tunnels]. I used a [single incision/two incision] technique. The repair was stable through full range of motion.”

If you use a graft, add:

“Due to significant tendon retraction and shortening, a [gracilis/semitendinosus] allograft was utilized to bridge a [X] cm defect. The graft was woven into the distal tendon stump and secured to the radial tuberosity.”

This level of detail justifies the use of 24342 and prevents denials.

CPT Code for Distal Biceps Tendon Repair vs. Proximal Repair

Do not confuse the distal repair with the proximal repair. They are completely different codes.

Proximal biceps repairs are far more common. They are often done for SLAP tears or tenosynovitis. Do not accidentally use a shoulder code for an elbow procedure. The reimbursement rates are different, and the medical necessity criteria are different.

Global Period and Post-Operative Care

Both 24341 and 24342 have a 90-day global period. This means the reimbursement includes all routine post-operative care for 90 days after surgery. Do not bill separately for follow-up visits, dressing changes, or staple removal unless there is a complication.

What about physical therapy? Physical therapy is usually separate, but check your payer policies. Some require a separate referral and pre-authorization for PT. Others consider the first few visits as part of the global package. When in doubt, ask.

Medicare and Distal Biceps Repair Codes

Medicare does not have a national coverage determination (NCD) specifically for distal biceps repair. However, local coverage determinations (LCDs) vary by region. Some Medicare Administrative Contractors (MACs) consider distal biceps repair “medically necessary” only for patients with a documented loss of supination greater than 50% compared to the opposite side.

If you bill Medicare, check your MAC’s LCD before surgery. You may need to document specific range-of-motion measurements in the preoperative note.

A Helpful List: Steps to Choose the Right Code

When you are staring at an operative report, follow these steps in order.

1. Confirm the tendon. Is it the distal biceps at the elbow? (Yes → continue. No → go to shoulder codes.)

2. Is it a repair or a debridement? Look for words like “reattach,” “fix,” or “suture.” If you see only “debride” or “release,” use 24340.

3. Is it acute or chronic? Less than 4 weeks? Likely 24341. More than 3 months? Likely 24342.

4. Is there a graft? Yes → 24342. No → go to step 5.

5. What incision technique? Single incision? Could be either. Check the complexity.

6. Does the surgeon mention “significant mobilization” or “extensive scar”? Yes → 24342. No → 24341.

This algorithm is not official, but it works in most private practice settings.

The Future of Distal Biceps Repair Coding

Coding rules change. The American Medical Association (AMA) updates the CPT manual every year. As of this writing, there is no dedicated code for “distal biceps repair with graft” or “endoscopic distal biceps repair.” But that could change.

Keep an eye on the AMA CPT Changes publication each fall. If enough surgeons adopt new techniques, the coding committee creates new codes. For now, we work with what we have: 24341 and 24342.

What Patients Should Know About the CPT Code

If you are a patient reading this, you might wonder why you should care about a CPT code. Here is why: That code determines how much your insurance company pays the hospital and the surgeon. If the code is wrong, your bill could be wrong.

You have the right to ask your surgeon’s billing office:

• “What CPT code will you bill for my surgery?”

• “Is this code for an acute repair or a complex reconstruction?”

If you had a chronic tear or a graft, make sure they are using the higher-complexity code (24342) if it is justified. If they use a lower code, your insurance might pay less, and you could be responsible for the balance.

Frequently Asked Questions (FAQ)

1. Can I use CPT 24342 for a two-incision distal biceps repair?

Technically, the code descriptor says “single incision technique.” Many coders use 24342 for two-incision repairs if the complexity is high, but this is a gray area. When in doubt, check with your local payer. Some prefer 24341 for traditional two-incision repairs.

2. What is the CPT code for distal biceps tendon repair with suture anchor?

Both 24341 and 24342 can include suture anchors. The anchor alone does not determine the code. The complexity and chronicity do.

3. Is there a separate code for the diagnostic arthroscopy before the open repair?

Yes, you can bill 29830 (diagnostic elbow arthroscopy) with Modifier 59 if the arthroscopy was medically necessary and distinct from the open repair. However, many payers deny this. Only bill it if the documentation clearly shows the arthroscopy provided information that changed the surgical plan.

4. What is the CPT code for distal biceps tenodesis?

Tenodesis (cutting the tendon and reattaching it to a different location) falls under 24342. The descriptor explicitly says “tenodesis or reattachment.”

5. How much does Medicare pay for 24341 and 24342?

Payment varies by geographic location. In 2024, the national average facility payment for 24342 is roughly 25-30% higher than 24341 due to the increased complexity. Check the Medicare Physician Fee Schedule for your specific locality.

6. Can I bill the repair and the graft harvest separately?

Sometimes. CPT 20924 is for tendon graft harvest. If the graft is harvested from a distant site (like the knee or foot) through a separate incision, you may bill it with Modifier 59. If the graft is harvested from the same elbow incision (e.g., palmaris longus), it is usually bundled.

7. What if the patient has a failed previous repair by another surgeon?

That is a revision procedure. Use 24342. Append Modifier 22 (increased procedural services) if the work is substantially greater than normal. Be prepared to send records.

Conclusion: Three Key Takeaways

Choosing the correct CPT code for distal biceps tendon repair comes down to complexity and chronicity, not just the use of anchors. For most straightforward acute repairs, CPT 24341 is your answer. For chronic tears, graft reconstructions, or repairs requiring extensive mobilization, CPT 24342 is the better choice. Always document thoroughly, check your payer policies, and never assume a single code fits every scenario.
