Find out how you need to document grafts.

Orthopedic coders frequently encounter varying terminology when reporting Achilles tendon reconstruction procedures. Terms such as reconstruction, augmentation, allograft, autograft, tendon transfer, and revision can complicate code selection. Accurate coding depends on determining whether the procedure represents a primary or secondary repair and whether the surgeon performed graft augmentation.

Get to Know the Achilles Tendon Repair Codes

The following CPT^® codes are the primary options for Achilles tendon rupture procedures:

When reviewing the operative report, look beyond the procedure title and focus on the work actually performed. Surgeons may use terms such as repair, reconstruction, augmentation, allograft, autograft, tendon transfer, or revision throughout the documentation. While these terms provide important clues, code selection ultimately depends on whether the repair is primary or secondary and whether the surgery required graft augmentation.

Understand Primary vs. Secondary Repair

A common source of confusion is the term primary repair. In this context, primary does not necessarily mean the patient’s first surgery. Rather, it refers to the initial treatment of the ruptured tendon.

A surgeon performs a secondary repair when a previous repair has failed, the tendon has re-ruptured, or additional surgery is necessary due to complications or persistent dysfunction.

Learn How to Code Chronic Achilles Ruptures

Chronic Achilles tendon ruptures are often associated with delayed presentation, tendon retraction, poor tissue quality, significant degeneration, or tendon defects that cannot be repaired with a simple end-to-end approximation. Documentation may describe these procedures as reconstruction, augmentation, bridging repair, or delayed repair.

One frequent coding misconception occurs when the surgeon documents the use of an allograft or autograft. Coders may be tempted to assign 27652 because the physician used a graft. However, many chronic ruptures are considered delayed or secondary repairs. In these cases, 27654 is typically appropriate because it describes a secondary repair with or without graft augmentation.

Examine the following examples to get a better understanding of how to code chronic rupture cases:

Example 1: Untreated Chronic Rupture

In the documentation, the surgeon noted the following operative findings:

• Rupture occurred four months earlier
• MRI demonstrated a 5 cm tendon gap
• Significant tendon degeneration was present
• Debridement and reconstruction were performed using an Achilles tendon allograft

Coding consideration: Although the surgeon used an allograft, the procedure was not a primary repair. The chronic nature of the rupture and reconstructive work performed support reporting 27654 rather than 27652.

Example 2: Chronic Rupture With Flexor Hallucis Longus (FHL) Transfer

The provider’s operative note lists the following findings:

• Poor native tissue quality associated with a chronic rupture
• Large tendon defect preventing direct repair
• FHL tendon transfer performed to restore plantar flexion strength

Coding consideration: Carefully review the operative report to determine whether you may report the tendon transfer separately according to CPT^® guidelines and National Correct Coding Initiative (NCCI) edits, or whether it is considered integral to the reconstruction performed. The provider should clearly document the harvest, transfer technique, fixation method, and clinical purpose.

Analyze These Revision and Re-Rupture Cases

A surgeon performs a revision procedure following a prior repair or after reconstruction has already been completed. Reasons for revision may include persistent dysfunction, failed healing, adhesions, infection, or other postoperative complications.

A re-rupture occurs when a previously repaired or reconstructed tendon ruptures again. The defining feature is failure of a prior repair or reconstruction. Re-rupture can occur following a primary repair, tendon reconstruction, or even a prior revision procedure.

Both revision and re-rupture cases often involve extensive scar tissue excision, debridement, mobilization of tendon ends, and graft supplementation. Code 27654 is generally the appropriate selection for these secondary repairs.

Check out the following examples of re-rupture repair cases:

Example 3: Failed Prior Achilles Repair

Under the operative findings, the physician documented the following:

• Achilles tendon repair performed one year earlier
• Chronic pain and weakness developed
• Imaging confirmed failure of the prior repair
• Reconstruction performed with allograft augmentation and scar tissue excision

Coding consideration: This represents revision of a previously repaired tendon. Because the repair is secondary in nature, 27654 is typically appropriate regardless of graft use.

Example 4: Postoperative Re-Rupture

The surgeon noted the following operative findings:

• New tendon rupture sustained following a prior surgical repair
• Revision repair performed using tendon grafting and suture anchor fixation

Coding consideration: The patient previously underwent Achilles tendon repair, making this a secondary repair. Code 27654 remains appropriate because it includes repair with or without grafting.

Keep This Documentation Checklist Handy

When reviewing Achilles tendon repair and reconstruction cases, confirm the following:

• Acute versus chronic rupture
• Prior repair history
• Primary versus secondary procedure
• Graft type and clinical indication
• Tendon defect size
• Tendon transfer performed
• Revision status and operative findings

You’ll also want to follow these practical coding steps:

1. Confirm that the procedure involves repair or reconstruction of a ruptured Achilles tendon.
2. Determine whether the repair is primary or secondary by reviewing the operative note for evidence of prior repair, failed repair, revision, or reinjury.
3. For primary repairs, determine whether a graft was used. Do not rely solely on the term augmentation.
4. Remember that 27654 includes secondary repair with or without graft augmentation.
5. Review the entire operative report. The procedure title, diagnosis, clinical history, and surgical technique should support the same clinical story.
6. Query the provider when documentation uses ambiguous terminology, such as graft augmentation, without clearly identifying the material used or the procedure performed.

Key Takeaway

For Achilles tendon reconstruction procedures, the presence of a graft alone does not determine code selection. Coders should focus on whether the repair is primary or secondary and carefully evaluate the operative documentation. Chronic ruptures, revisions, and re-ruptures generally support reporting 27654, even when the surgeon performs an allograft or autograft augmentation.
