Longitudinal reduction defect of radius
ICD-10 Q71.4 is a billable code used to indicate a diagnosis of longitudinal reduction defect of radius.
Longitudinal reduction defect of the radius is a congenital malformation characterized by the underdevelopment or absence of the radius bone in the forearm. This condition can lead to significant functional impairment, affecting the range of motion and strength of the affected limb. It may present as a unilateral or bilateral condition and is often associated with other congenital anomalies, such as those affecting the ulna or hand. Clinically, patients may exhibit a shortened forearm, radial deviation of the wrist, and functional limitations in grasping and manipulation. Diagnosis typically involves physical examination and imaging studies, such as X-rays, to assess the extent of the defect and any associated skeletal abnormalities. Management may include orthopedic interventions, such as corrective surgery or the use of prosthetics, to improve function and appearance. Early intervention is crucial for optimizing outcomes and enhancing the quality of life for affected individuals.
Documentation should include detailed physical examination findings, imaging results, and any functional assessments performed. Growth and developmental milestones should also be noted.
A pediatric patient presents with a shortened forearm and limited wrist mobility; imaging reveals a longitudinal reduction defect of the radius.
Coders should ensure that all associated conditions are documented and coded appropriately to reflect the full clinical picture.
Genetic testing results, family history of congenital conditions, and any syndromic associations should be documented.
A child with a longitudinal reduction defect of the radius undergoes genetic counseling due to a family history of limb malformations.
Coders must be aware of the potential for syndromic associations and ensure that genetic documentation supports the diagnosis.
Used in cases where surgical intervention is required for functional improvement.
Document the nature of the defect and the surgical approach taken.
Orthopedic specialists should provide detailed operative notes.
A longitudinal reduction defect refers to a partial underdevelopment of the radius, while a complete absence indicates that the radius is entirely missing. Accurate coding is essential to reflect the specific nature of the condition.
