ICD Code M67.51

ICD code M6751 is used to identify and classify the medical condition known as plica syndrome specifically affecting the right knee. Plica syndrome occurs when a fold in the thin tissue lining the knee joint, known as the plica, becomes irritated or inflamed. This can lead to knee pain, swelling, and a feeling of instability or clicking in the joint. The code M6751 helps healthcare providers document and communicate this specific diagnosis for treatment planning, billing, and insurance purposes.

When considering the use of the ICD code for Plica syndrome of the right knee, the following diagnostic criteria and symptoms should be evaluated:

1. Patient History
- Previous knee injuries or trauma.
- History of repetitive knee motion or overuse.

2. Physical Examination Findings
- Tenderness along the medial or lateral aspect of the knee.
- Swelling or effusion in the knee joint.

3. Range of Motion Assessment
- Limited range of motion, particularly in flexion and extension.
- Pain during specific movements, such as squatting or climbing stairs.

4. Palpation Results
- Palpable plica or thickened tissue in the knee joint.
- Reproduction of symptoms upon palpation of the plica.

5. Imaging Studies
- MRI or ultrasound showing thickened plica or associated inflammation.
- Exclusion of other knee pathologies (e.g., meniscus tears, ligament injuries).

6. Symptomatology
- Pain localized to the knee, especially during activity.
- Clicking or popping sensations in the knee during movement.
- Symptoms worsening with activity and improving with rest.

7. Response to Conservative Treatment
- Evaluation of symptom relief following rest, ice, compression, and elevation (RICE).
- Assessment of response to physical therapy interventions.

These criteria should be thoroughly assessed to determine the appropriateness of using the ICD code for Plica syndrome of the right knee.

For the ICD code M67.51, which pertains to plica syndrome of the right knee, the relevant CPT codes that may be applicable for treatment include:

1. 29870 - Arthroscopy, knee, diagnostic, with or without synovial biopsy (separate procedure).

2. 29875 - Arthroscopy, knee, surgical; synovectomy, limited (e.g., plica or shelf resection).

3. 29876 - Arthroscopy, knee, surgical; synovectomy, major, two or more compartments.

4. 29877 - Arthroscopy, knee, surgical; debridement/shaving of articular cartilage (chondroplasty).

5. 29880 - Arthroscopy, knee, surgical; with meniscectomy (medial AND lateral, including any meniscal shaving).

These CPT codes are commonly used in the treatment of conditions related to the knee, including procedures that may address issues associated with plica syndrome. It is important for healthcare providers to select the appropriate CPT code based on the specific procedure performed.
