Varus deformity, not elsewhere classified
ICD-10 M21.1 is a billable code used to indicate a diagnosis of varus deformity, not elsewhere classified.
Varus deformity refers to a condition where a limb or joint is angled inward, resulting in a bowing appearance. This deformity can occur in various parts of the body, including the knees, elbows, and toes. In the context of acquired deformities, varus deformities can arise due to conditions such as osteoarthritis, trauma, or developmental issues. Finger and toe abnormalities, including hallux valgus (bunion), can also be associated with varus deformities, where the alignment of the digits is altered, leading to functional impairment and discomfort. Corrective procedures may include osteotomy, where the bone is cut and realigned, or arthrodesis, which fuses the joint to correct the deformity. Accurate coding of varus deformity is essential for appropriate treatment planning and reimbursement, as it often requires a multidisciplinary approach involving orthopedic surgeons, physical therapists, and podiatrists.
Detailed descriptions of the deformity, imaging results, and treatment plans.
Patients presenting with knee varus deformity due to osteoarthritis requiring surgical intervention.
Ensure that the documentation specifies the location and severity of the deformity for accurate coding.
Foot examination findings, including alignment and functional assessment.
Patients with hallux varus presenting for corrective surgery.
Document any conservative treatments attempted prior to surgical intervention.
Used in conjunction with M21.1 when correcting hallux varus.
Document the indication for surgery and pre-operative assessments.
Orthopedic surgeons should ensure that the deformity is well documented to justify the procedure.
Varus deformities involve inward angulation of the limb or joint, while valgus deformities involve outward angulation. Accurate coding requires understanding these distinctions.
