Code Description

ICD-10 M21.02 is a billable code used to indicate a diagnosis of valgus deformity, not elsewhere classified, elbow.

Key Diagnostic Point:

Valgus deformity of the elbow is characterized by an abnormal angulation of the forearm relative to the upper arm, resulting in an outward deviation of the forearm when the arm is extended. This condition can be acquired due to various factors, including trauma, repetitive stress, or underlying conditions such as arthritis. The deformity can lead to functional limitations, pain, and increased risk of joint degeneration. Patients may present with symptoms such as discomfort during movement, difficulty in performing daily activities, and a noticeable change in the alignment of the elbow joint. Treatment options may include physical therapy, bracing, or surgical interventions aimed at correcting the alignment and restoring function. It is essential for healthcare providers to document the specific nature of the deformity, any associated symptoms, and the impact on the patient's quality of life to ensure accurate coding and appropriate management.
