Unspecified acquired deformity of left thigh

This code signifies a non-congenital, unspecified structural abnormality or malformation affecting the left thigh. This could include changes in shape, size, or alignment that are not present at birth and whose specific nature is not documented.

Apply this code when documentation indicates an acquired deformity of the left thigh, but the specific type of deformity (e.g., valgus, varus, shortening, lengthening) is not specified. This code is appropriate when the provider notes "deformity of left thigh, unspecified acquired" or similar.

• Avoid using this code if a more specific acquired deformity of the left thigh is documented (e.g., M21.052 for valgus deformity).
• Ensure the documentation clearly states "acquired" rather than congenital; congenital deformities are coded differently.
• Always query the provider for greater specificity if possible, to allow for more precise coding.
