Selecting the correct ACL repair CPT code requires more than identifying a torn anterior cruciate ligament. Coders must review the surgical approach, repair technique, graft source, and associated injuries.29888 covers arthroscopically aided ACL repair, augmentation, or reconstruction. However, open procedures and avulsion fracture treatments require different coding considerations. statesc.southcarolinablues.comThis guide explains those distinctions through procedure comparisons, documentation requirements, and practical examples. Always apply the code set and payer requirements effective on the service date.
Additionally, avoid automatically reporting ligament repair alongside fracture fixation for the same restorative work.
Graft preparation also requires careful review. Do not assume every preparation task represents an additional billable service.Furthermore, preserve implant records and tissue documentation. These records help explain discrepancies between professional claims and facility charges.
Track recurring errors through medical coding audits. Then use findings to improve documentation templates and claim review.Additionally, separate coding corrections from coverage appeals. Each issue requires different evidence.
ACL Repair CPT Code Selection by Procedure and Surgical Approach
The operative report establishes the coding pathway. Scheduling descriptions, authorization requests, and patient terminology may describe different procedures.For example, patients frequently call reconstruction an ACL repair. Nevertheless, coders must identify whether surgeons repaired native tissue or reconstructed the ligament.Before choosing an ACL repair CPT code, confirm:- Primary repair, augmentation, or reconstruction.
- Arthroscopically aided or open approach.
- Soft-tissue tear or avulsion fracture.
- Right or left knee.
- Graft source and harvest location.
- Additional procedures and anatomic sites.

Arthroscopic ACL Repair CPT Code: Reporting 29888
Procedures Addressed by 29888
Code 29888 addresses arthroscopically aided anterior cruciate ligament repair, augmentation, or reconstruction. Therefore, it does not describe reconstruction exclusively.An arthroscopic ACL repair CPT code search commonly leads to this code. However, the surgeon must document work matching its requirements.Repair preserves and reconnects native ligament tissue. Reconstruction replaces the ligament using graft tissue.Although 29888 encompasses these techniques, the clinical record should identify the actual procedure.Arthroscopic Assistance Versus an Open Procedure
An ACL repair CPT code should reflect the operative technique rather than incision size.Surgeons may create incisions for graft harvest, tunnel access, or fixation during arthroscopically aided reconstruction. Those incisions alone do not establish open ligament reconstruction.Read the complete operative narrative. Request clarification when the approach remains unclear.Diagnostic Arthroscopy During ACL Surgery
Diagnostic arthroscopy forms part of surgical arthroscopy during the same encounter. Consequently, do not add 29870 for routine inspection preceding arthroscopic ACL treatment.The CMS musculoskeletal NCCI manual explains this inclusion. Chapter 4Open ACL Repair CPT Code: Primary Repair Versus Reconstruction
Open Primary Cruciate Ligament Repair
For an open ACL repair CPT code, review 27407 when the surgeon documents primary cruciate ligament repair.The report should describe ligament reattachment, suturing, and the open approach. Avoid assigning this code solely because documentation mentions an incision.Furthermore, distinguish primary repair from graft-based reconstruction.Open ACL Reconstruction and Augmentation
An ACL repair CPT code cannot represent every open reconstructive technique.Review 27428 for open intra-articular ligament reconstruction. Meanwhile, 27427 addresses extra-articular reconstruction, and 27429 addresses combined intra-articular and extra-articular reconstruction. statesc.southcarolinablues.comMultiple ligament procedures require additional analysis. Confirm the structures treated and applicable reporting restrictions before assigning multiple codes.The orthopedic billing and coding guide provides related background on orthopedic claims.ACL Avulsion Fracture Repair CPT Code: Coding the Fracture Treatment
Bony Avulsion Versus Soft-Tissue ACL Avulsion
An avulsion may involve a bone fragment or detached ligament tissue. These findings create different coding pathways.A tibial spine avulsion involves the ligament’s bony attachment. Conversely, soft-tissue avulsion does not necessarily involve a fracture.Therefore, an ACL repair CPT code should not replace appropriate fracture coding without reviewing the operative findings.Arthroscopically Aided Avulsion Fracture Treatment
For an ACL avulsion fracture repair CPT code, evaluate the fracture location and fixation.Code 29850 addresses qualifying arthroscopically aided fracture treatment without internal or external fixation. Code 29851 addresses qualifying treatment with fixation.Both pathways include arthroscopy. Current payer code lists maintain this distinction. bluecrossma.orgOpen Avulsion Fracture Treatment
Review 27540 for open treatment of qualifying intercondylar spine or tuberosity fractures.Confirm the fracture location before selecting this code. Do not apply it automatically to every injury labeled “ACL avulsion.”Avulsion Documentation Table
| Finding | Documentation needed |
| Bony avulsion | Exact fracture location |
| Arthroscopic treatment | Approach and fracture management |
| Fixation | Method and devices used |
| Open treatment | Exposure and fracture treatment |
| Soft-tissue avulsion | Ligament attachment and repair technique |
ACL Repair Right Knee CPT Code and Left Knee Reporting
Right Knee ACL Procedures
The ACL repair CPT code generally remains unchanged between right and left knees. Laterality modifiers identify the operative side when required.For supported arthroscopically aided right ACL surgery, 29888-RT illustrates right-sided reporting. However, modifier requirements depend on the payer.Arthroscopic Left ACL Repair
Similarly, 29888-LT illustrates supported left-sided reporting.An arthroscopic left ACL repair CPT code does not require a separate left-specific base code. Instead, match the procedure, modifier, and diagnosis laterality.Matching Laterality Across the Claim
Compare the operative report against imaging, authorization, and claim fields. Resolve conflicting sides before submission.Moreover, select diagnosis codes from the documented injury and encounter circumstances. Do not infer the diagnosis from the procedure alone.ACL Repair With Allograft CPT Code: Procedure and Tissue Reporting
Coding the Underlying ACL Procedure
The ACL repair CPT code depends on the operative work, rather than donor tissue alone.Arthroscopically aided reconstruction using an allograft generally follows the 29888 pathway when documentation supports it. Allograft use does not automatically establish another primary procedure code.Allograft Documentation and Billing Considerations
Document the graft source, tissue type, preparation, and implantation. Also, distinguish professional procedure reporting from facility tissue charges.A facility may face separate supply-reporting requirements. However, reporting a charge does not guarantee additional payment.Review contractual terms, setting requirements, and payer instructions. Never assume the surgeon can separately bill the donor graft purchase.ACL Repair With Hamstring Autograft CPT Code
Reconstruction Using the Patient’s Hamstring Tendon
A hamstring autograft uses the patient’s tendon to reconstruct the ligament.For arthroscopically aided reconstruction, the ACL repair CPT code commonly remains 29888. Nevertheless, the operative report must establish the technique.Document the harvested tendon and operative side. Also, distinguish graft harvest from ligament implantation.Graft Harvest and Separate Reporting
A separate incision does not automatically support separate harvest billing.Review harvest location, current CPT guidance, applicable edits, and payer instructions. Do not automatically add 20924 whenever the surgeon harvests a hamstring tendon.CMS restricts separate tissue-transfer reporting when the primary code includes that work. However, this general rule does not resolve every ACL harvest scenario. Chapter 4Consequently, evaluate the complete procedure rather than relying on an isolated graft reference.Graft for ACL Repair CPT Code: Autograft, Allograft, and Supply Distinctions
The ACL repair CPT code identifies the supported ligament procedure. Graft-related reporting requires a separate assessment.| Graft component | Coding consideration |
| Hamstring autograft | Harvest location and inclusion rules |
| Patellar tendon autograft | Technique and associated harvest documentation |
| Quadriceps tendon autograft | Source and applicable reporting guidance |
| Donor allograft | Facility tissue reporting and payment rules |
| Fixation devices | Supply reporting and payment packaging |
CPT Code for ACL Repair With BEAR Implant
Bridge-Enhanced ACL Restoration and Operative Documentation
The ACL repair CPT code for a BEAR procedure requires review of the documented surgical technique.BEAR supports healing of the patient’s native ligament. It differs from reconstruction using a donor or harvested tendon.The manufacturer’s official BEAR information explains the implant’s role in ligament healing. Miach OrthopaedicsDocument native tissue repair, approach, implant placement, and associated work. Avoid describing the implant as a tendon allograft.Procedure Coding, Implant Reporting, and Coverage
Assess whether 29888 describes the documented arthroscopically aided repair. Confirm current coding guidance and payer instructions before submission.Separately review:- Professional procedure reporting.
- Facility implant charges.
- Medical necessity requirements.
- Coverage exclusions.
- Authorization conditions.
Additional Procedures Performed With ACL Repair
ACL Surgery With Meniscus Repair or Meniscectomy
The ACL repair CPT code does not automatically describe every additional knee procedure.For example, evaluate 29882 for one meniscus repair and 29883 for medial and lateral repairs. Meniscectomy follows different code selections.Identify the meniscus treated and the work performed. Then review current code-pair edits before reporting additional services.Chondroplasty, Synovectomy, and Other Arthroscopic Work
CMS restricts separate reporting of 29874 and 29877 with other knee arthroscopy codes.G0289 may apply under specific circumstances. Nevertheless, compartment differences alone do not resolve every reporting restriction.Limited incidental synovectomy also requires careful review. Do not assign additional codes simply because the surgeon removed tissue. Chapter 4Current NCCI Edit Review
Check edits for the service date and claim setting. CMS updates procedure-to-procedure edit files quarterly. www.cms.govConfirm the modifier indicator and supporting circumstances. Never append modifier 59 solely to obtain payment.Operative Documentation Required for Accurate ACL Coding
An ACL repair CPT code requires clear, consistent operative documentation.The surgeon should record:- Right or left knee.
- Ligament involved.
- Tear location.
- Native tissue condition.
- Repair, augmentation, or reconstruction.
- Surgical approach.
- Fracture presence and location.
- Reduction and fixation details.
- Graft source and harvest location.
- Implant identification.
- Additional procedures and compartments.
Common ACL Coding Errors and Denial Prevention
An incorrect ACL repair CPT code can trigger edits, payment delays, or documentation requests.However, not every denial indicates an incorrect procedure code. Investigate authorization, eligibility, modifiers, and contractual requirements before changing coding.| Common error | Corrective action |
| Coding from the scheduled procedure | Review the completed operative report |
| Confusing repair with reconstruction | Confirm native tissue versus graft reconstruction |
| Missing an avulsion fracture | Verify fracture anatomy and treatment |
| Reporting the wrong side | Reconcile laterality across records |
| Automatically adding harvest charges | Review inclusion rules and edits |
| Assuming implant coverage | Check patient-specific benefits |
| Adding unsupported modifiers | Validate distinct-service requirements |
Practical ACL Coding Scenarios
These examples illustrate coding pathways. Each assumes documentation supports the described procedure.Arthroscopically Aided Right ACL Reconstruction With Allograft
The surgeon reconstructs the right ACL using donor tendon tissue.Review 29888 with RT when the payer requires laterality. Separately evaluate facility graft reporting.Do not add another ligament procedure code solely because the surgeon uses an allograft.Arthroscopic Left ACL Reconstruction With Hamstring Autograft
The surgeon harvests a hamstring tendon and reconstructs the left ACL.Review 29888-LT when appropriate. Then evaluate harvest reporting without assuming the separate incision supports another code.Open Primary ACL Repair Without Reconstruction
The surgeon directly repairs native cruciate tissue through an open approach.Review 27407 against the operative details. Do not substitute a reconstruction code merely because the surgery restores stability.Arthroscopically Aided Tibial Spine Avulsion Fixation
The surgeon reduces and fixes a qualifying tibial spine fracture.Review 29851 when documentation establishes arthroscopically aided fracture treatment with fixation. Avoid automatically adding 29888 for the same restorative work.ACL Repair With a BEAR Implant
The surgeon documents arthroscopically aided native ligament repair with implant placement.Assess 29888 against the procedure description. Separately verify implant coverage, facility reporting, and authorization conditions.ACL Reconstruction With Meniscus Repair
The surgeon reconstructs the ACL and repairs a documented meniscus tear.Evaluate 29888 and the appropriate meniscus repair code. Confirm current edits, modifiers, and documentation before reporting both.Conclusion
The correct ACL repair CPT code follows the documented operation, surgical approach, and injury pattern.Distinguish arthroscopic ligament procedures from open repair and avulsion fracture treatment. Additionally, review graft harvest, implant coverage, and concurrent procedures individually.Clear documentation supports consistent coding decisions. Current CPT instructions, official payer policies, and applicable edits complete the review.Frequently Asked Questions (FAQs)
Get clear answers about ACL repair CPT codes, including arthroscopic procedures, open repairs, grafts, and avulsion fractures. Understand coding requirements, modifiers, and documentation to support accurate billing.
Which CPT code applies to arthroscopic ACL repair?
CPT code 29888 covers arthroscopically aided ACL repair, augmentation, or reconstruction. Select it when the operative report supports the procedure.
Does open ACL repair use the same code as reconstruction?
No. 27407 addresses primary cruciate ligament repair. Open intra-articular reconstruction may support 27428, depending on the documented work.
Which CPT code applies to ACL avulsion fracture repair?
For qualifying arthroscopically aided fracture treatment, review 29850 without fixation or 29851 with fixation. Confirm the fracture location and technique.
Does an allograft change the arthroscopic ACL procedure code?
Allograft use alone does not change the primary code. 29888 applies when the documented arthroscopically aided procedure meets its requirements. Review facility tissue reporting separately.
Can coders bill diagnostic arthroscopy separately during arthroscopic ACL surgery?
No. Surgical arthroscopy includes diagnostic arthroscopy during the same encounter. Do not separately report routine diagnostic inspection preceding arthroscopic ACL treatment.
Does a BEAR implant replace the ACL with donor tissue?
No. The BEAR implant supports healing of the patient’s native ACL. It differs from reconstruction using a donor tendon graft.
