Other disorders of bone development and growth, right femur

This code signifies a non-specific developmental or growth abnormality affecting the right femur. It encompasses various conditions where the bone's formation or growth process is disrupted, leading to structural or functional impairments, excluding more specific diagnoses like osteogenesis imperfecta or Paget's disease.

Apply this code when documentation indicates an unspecified or "other" disorder of bone development or growth specifically impacting the right femur. This is appropriate when a more precise diagnosis from the M89.2 subcategory (e.g., M89.20 for unspecified site) is not supported, and the laterality is clearly documented.

• Ensure documentation specifies "right femur" to support laterality.
• Avoid using this code if a more specific M89.2 subcategory code (e.g., M89.21 for osteomalacia) is applicable.
• Query the provider for a more precise diagnosis if the documentation is vague regarding the specific type of bone development or growth disorder.
