In simple words: This code describes a birth defect where the smaller bone in the lower leg (fibula) is shorter than usual or not fully formed, causing a leg deformity.

Q72.6, Longitudinal reduction defect of the fibula, is an ICD-10-CM code classifying a congenital condition where the fibula, the smaller of the two lower leg bones, is underdeveloped or abnormally short along its length. This can result in various degrees of leg deformity and functional limitations, depending on the severity of the defect.

Example 1: A newborn infant is diagnosed with a significantly shortened fibula, resulting in a noticeable bowing of the leg.The condition is identified during the routine physical exam., A child presents with persistent leg pain and difficulty walking.Imaging studies reveal a longitudinal reduction defect of the fibula, necessitating corrective surgery., During a prenatal ultrasound, a longitudinal reduction defect of the fibula is detected in a fetus. Genetic testing and counseling are recommended for the parents.

Complete prenatal history (if applicable), physical examination findings, radiographic images (X-rays, MRI, CT scans), genetic test results (if performed), surgical reports (if applicable), and physical therapy notes.

** Further clarification may be needed depending on the severity and associated anomalies.The diagnosis should be confirmed through appropriate imaging and clinical evaluation.
