Major osseous defect, right hand

This code signifies a significant structural deficiency or loss of bone tissue in the right hand. This defect is substantial enough to be considered "major," implying a significant impact on the hand's anatomy and function. It typically results from trauma, disease, or congenital anomalies.

This code is appropriate when documentation clearly indicates a major osseous defect affecting the right hand. This could include conditions like large bone cysts, significant bone loss due to osteomyelitis, or extensive non-union following a fracture. Supporting documentation should specify the location (right hand) and the severity (major) of the defect.

• Ensure documentation specifies "major" to differentiate from minor defects or non-specified osseous defects.
• Always verify laterality (right hand) as separate codes exist for the left hand and unspecified hand.
• Consider sequencing this code after a primary diagnosis describing the underlying cause of the defect, if applicable (e.g., fracture, osteomyelitis).
