Other specified acquired deformities of unspecified thigh

This code signifies an acquired, non-congenital structural abnormality of the thigh that is not otherwise classified by more specific ICD-10-CM codes. It represents a deformity that developed after birth due to various factors such as trauma, disease, or iatrogenic causes, affecting the overall shape or alignment of the thigh region.

Use this code when documentation specifies an acquired deformity of the thigh, but the exact nature or specific type of deformity (e.g., valgus, varus, shortening) is not detailed enough for a more precise code. It is appropriate when the laterality of the thigh is not specified in the medical record. Supporting documentation would include physician notes describing an "acquired thigh deformity" without further specification of type or side.

• Always attempt to obtain clarification from the provider if the specific type of acquired thigh deformity or laterality is not documented to allow for a more precise code.
• Avoid using this code if a more specific code for an acquired deformity of the thigh (e.g., M21.15- for valgus deformity, M21.25- for varus deformity) can be assigned based on the clinical documentation.
• Ensure the documentation clearly states "acquired" to differentiate from congenital deformities (Q codes).
