Chondromalacia patellae, unspecified knee
ICD-10 M22.40 is a billable code used to indicate a diagnosis of chondromalacia patellae, unspecified knee.
Chondromalacia patellae refers to the softening and breakdown of the cartilage on the underside of the kneecap (patella). This condition often results from overuse, injury, or misalignment of the knee joint, leading to pain and dysfunction. Patients typically present with anterior knee pain, which may worsen with activities such as climbing stairs, squatting, or sitting for prolonged periods. The condition is often associated with internal derangements of the knee, including meniscal tears and ligament injuries, which can complicate the clinical picture. Diagnosis is primarily clinical, supported by imaging studies such as MRI or X-rays to rule out other pathologies. Treatment may include conservative measures like physical therapy, anti-inflammatory medications, and activity modification. In more severe cases, arthroscopic procedures may be indicated to address cartilage damage or to repair associated injuries. Accurate coding is essential for proper reimbursement and to reflect the complexity of the patient's condition.
Detailed operative reports, pre-operative assessments, and post-operative follow-ups are essential.
Patients presenting with knee pain, history of trauma, or chronic knee issues requiring surgical intervention.
Ensure that all associated conditions are documented to support the complexity of the case.
Comprehensive evaluations, treatment plans, and progress notes are necessary.
Patients undergoing rehabilitation for knee pain or post-operative recovery.
Document functional limitations and response to therapy to justify ongoing treatment.
Used when performing a diagnostic arthroscopy to evaluate chondromalacia.
Document indications for surgery and findings during the procedure.
Orthopedic surgeons should ensure that all findings are clearly documented.
The primary symptom is anterior knee pain, often exacerbated by activities such as climbing stairs or sitting for long periods.
Diagnosis is typically made through a combination of clinical evaluation and imaging studies, such as MRI.
Treatment options include physical therapy, anti-inflammatory medications, and in some cases, surgical intervention.
