Unequal limb length (acquired), unspecified ulna and radius
ICD-10 M21.739 is a billable code used to indicate a diagnosis of unequal limb length (acquired), unspecified ulna and radius.
Unequal limb length, or limb length discrepancy, refers to a condition where one limb is shorter or longer than the other due to acquired factors. This can occur due to various reasons such as trauma, surgical interventions, or diseases affecting bone growth and development. In the case of M21.739, the specific focus is on the ulna and radius, which are the two long bones in the forearm. Acquired deformities can arise from conditions such as fractures that heal improperly, infections that affect bone integrity, or conditions like osteomyelitis. Patients may present with functional limitations, gait abnormalities, or cosmetic concerns. Treatment options often include corrective procedures such as limb lengthening, osteotomy, or the use of orthotic devices to improve function and appearance. Accurate coding is essential for proper reimbursement and to reflect the complexity of the patient's condition and treatment plan.
Detailed clinical notes including measurements of limb lengths, imaging studies, and treatment plans.
Patients presenting with post-fracture limb length discrepancies or those requiring corrective surgery.
Ensure that all relevant imaging and surgical notes are included to support the diagnosis and treatment.
Comprehensive assessments of functional limitations and rehabilitation goals.
Patients undergoing rehabilitation post-surgery for limb lengthening or correction.
Document functional assessments and progress notes to justify the need for ongoing therapy.
Used when performing corrective surgery for limb length discrepancy.
Detailed operative notes and pre-operative assessments.
Orthopedic specialists should ensure all relevant imaging and measurements are documented.
Congenital unequal limb length is present at birth due to genetic or developmental factors, while acquired unequal limb length develops later in life due to trauma, disease, or surgical interventions.
