Unequal limb length (acquired), unspecified femur
ICD-10 M21.759 is a billable code used to indicate a diagnosis of unequal limb length (acquired), unspecified femur.
Unequal limb length, or limb length discrepancy (LLD), refers to a condition where one limb is shorter or longer than the other, which can be acquired due to various factors such as trauma, surgery, or disease. In the case of M21.759, the focus is on the femur, the longest bone in the body, which can be affected by conditions such as fractures, infections, or tumors that may lead to growth disturbances or deformities. Acquired limb length discrepancies can result from conditions like osteomyelitis, which can damage the growth plate, or from surgical interventions that may inadvertently alter limb length. Patients may experience functional limitations, gait abnormalities, and discomfort, necessitating corrective procedures. Treatment options may include limb lengthening surgeries, orthopedic braces, or physical therapy to improve function and alleviate symptoms. Accurate coding for this condition is crucial for appropriate management and reimbursement, as it often requires multidisciplinary approaches involving orthopedic surgeons, physical therapists, and rehabilitation specialists.
Detailed clinical notes on the cause of LLD, treatment plans, and outcomes.
Post-traumatic limb length discrepancies, surgical corrections, and pre-operative assessments.
Ensure accurate measurement of limb lengths and clear documentation of any surgical interventions.
Progress notes detailing functional assessments and treatment interventions.
Rehabilitation following limb lengthening procedures or corrective surgeries.
Document functional limitations and progress towards rehabilitation goals.
Used in cases of significant limb length discrepancy requiring surgical intervention.
Pre-operative assessment, surgical notes, and post-operative follow-up documentation.
Orthopedic surgeons must document the rationale for surgery and expected outcomes.
Congenital limb length discrepancy is present at birth and often results from genetic factors or developmental issues, while acquired limb length discrepancy develops later in life due to trauma, surgery, or disease.
