Understanding Patellar Tendon Repair
Patellar tendon repair is a surgical intervention performed to address ruptures or tears of the patellar tendon, which connects the kneecap (patella) to the shinbone (tibia). Such injuries often result from trauma, sports injuries, or degenerative conditions, leading to functional impairment and difficulty with knee extension.
Indications for Surgery
Patellar tendon repair is typically indicated when:
- Complete rupture of the patellar tendon
- Partial tears causing significant functional deficits
- Failed conservative management
- Associated injuries requiring surgical intervention
Surgical Techniques
Various techniques exist for patellar tendon repair:
- Primary repair with sutures
- Augmentation with grafts or synthetic materials
- Open versus arthroscopic approaches
- Use of anchors, transosseous tunnels, or suture anchors
The specific technique used influences the coding and billing process, making precise documentation crucial.
Overview of CPT Codes for Patellar Tendon Repair
CPT codes are standardized codes maintained by the American Medical Association (AMA) that describe medical, surgical, and diagnostic services. For patellar tendon repair, several CPT codes may apply depending on the procedure performed.
Primary CPT Codes for Patellar Tendon Repair
The main CPT codes that generally encompass patellar tendon repair procedures include:
- 27560 – Repair, primary, rupture or laceration, of extensor mechanism of knee, age 8 or older
- 27562 – Repair, secondary, extensor mechanism of knee, age 8 or older
- 27650 – Repair, quadriceps or patellar tendon, primary, age 8 or older
- 27652 – Repair, quadriceps or patellar tendon, secondary, age 8 or older
- 27654 – Repair, quadriceps or patellar tendon, with graft, age 8 or older
Note that the choice among these codes depends on whether the repair is primary or secondary, the location of the injury, and whether a graft or augmentation is involved.
Additional Related Codes
Other CPT codes may be applicable depending on ancillary procedures:
- 27412 – Anterior cruciate ligament reconstruction (if performed concurrently)
- 29888 – Arthroscopically aided ligament repair or reconstruction
- 27405 – Arthroscopic knee meniscectomy (if performed alongside)
Proper selection of codes requires careful review of operative reports and documentation.
Guidelines for Coding Patellar Tendon Repairs
Accurate coding hinges on understanding specific guidelines issued by the AMA and CMS (Centers for Medicare & Medicaid Services).
Primary vs. Secondary Repairs
- Primary repair (27560, 27650): Used when the tendon is repaired in a fresh injury without prior attempts.
- Secondary repair (27562, 27652): Applicable when the tendon has failed previous repair or is delayed.
- Repair with graft (27654): When a graft or augmentation device is used to reinforce the repair.
Age Considerations
Codes specify "age 8 or older," which guides the coder to select appropriate codes based on patient age.
Laterality and Documentation
Ensure that the operative report clearly states:
- Side of the repair (left or right knee)
- Type of repair performed (primary, secondary, with graft)
- Details about the technique used
Use of Modifiers
Modifiers are essential for precise billing:
- RT – Right side
- LT – Left side
- 59 – Distinct procedural service, if multiple procedures are performed
Common Coding Scenarios and Examples
Understanding real-world examples can clarify CPT coding practices.
Example 1: Primary Patellar Tendon Repair
A 25-year-old athlete sustains a complete rupture of the right patellar tendon. The surgeon performs an open primary repair using sutures. The appropriate CPT code is:
- 27560 – Repair, primary, rupture or laceration, of extensor mechanism of knee, age 8 or older
The billing should include the modifier RT to specify the right knee.
Example 2: Secondary Repair with Graft Augmentation
A 30-year-old patient with a failed previous repair undergoes a secondary repair with graft augmentation. The CPT code used is:
- 27654 – Repair, quadriceps or patellar tendon, with graft, age 8 or older
Modifiers like RT or LT are added based on the side involved.
Documentation Tips for Accurate CPT Coding
Proper documentation supports correct CPT code assignment and ensures compliance:
- Describe the injury (rupture, laceration, tear)
- Specify whether the repair is primary or secondary
- Detail the surgical technique, including use of grafts or anchors
- Note the side of the procedure
- Include any additional procedures performed
Conclusion
Accurate coding of patellar tendon repair procedures using CPT codes is fundamental for effective billing and reimbursement. Understanding the distinctions between primary and secondary repairs, graft involvement, and the appropriate use of modifiers helps ensure compliance and minimizes claim denials. Always refer to the latest CPT coding guidelines and ensure thorough documentation in operative reports. By staying informed and meticulous, healthcare providers and billing professionals can facilitate smooth administrative processes and focus on delivering quality orthopedic care.

Frequently Asked Questions
What is the CPT code for patellar tendon repair?
The CPT code commonly used for patellar tendon repair is 27358, which covers repair of the extensor mechanism of the knee, including the patellar tendon.
Are there different CPT codes based on the type of patellar tendon repair performed?
Yes, CPT codes vary depending on whether the repair is open or arthroscopic, the extent of the repair, and any additional procedures performed. For example, 27358 is for open repair, while other codes may apply for associated procedures.
How does the CPT coding differ for primary versus revision patellar tendon repair?
Primary repair is typically coded as 27358, whereas revision procedures may require different codes or modifiers to specify the complexity and nature of the revision surgery.
What modifiers are commonly used with CPT codes for patellar tendon repair?
Modifiers such as -51 (Multiple Procedures), -59 (Distinct Procedural Service), or -LT/-RT (Left/Right limb) may be used to specify multiple procedures or laterality in CPT coding for patellar tendon repairs.
Are there specific CPT codes for minimally invasive or arthroscopic patellar tendon repair?
Yes, arthroscopic procedures involving the patellar tendon may be coded with specific arthroscopy CPT codes, such as 29827, depending on the exact procedure performed, in addition to repair codes.
How do insurance companies typically verify CPT codes for patellar tendon repair?
Insurance companies verify CPT codes against operative reports and documentation to ensure the procedures billed match the services provided, often requiring detailed operative notes for approval.
Can CPT codes for patellar tendon repair be bundled with other knee procedures?
Yes, certain CPT codes may be bundled if performed together during the same operative session. However, modifiers like -51 or -59 may be used to indicate distinct procedures when appropriate.
What resources are available for accurate CPT coding of patellar tendon repair?
Resources include the AMA CPT Professional Edition, coding guidelines, payer-specific coding policies, and consultation with certified medical coders to ensure accurate billing and coding.
