Oth disorders of bone development and growth, multiple sites

This code signifies a diagnosis of various non-specific abnormalities in bone formation or maturation that affect multiple anatomical locations. These are conditions where the bones do not develop or grow normally, leading to structural or functional impairments across the skeletal system.

Apply this code when documentation indicates a generalized disorder of bone development or growth that is not classified elsewhere and affects more than one site. This includes conditions like osteodysplasia or skeletal dysplasias that are not specified by a more precise code. Supporting documentation should clearly state the multi-site involvement and the nature of the developmental or growth abnormality.

• Ensure the documentation explicitly states "multiple sites" or describes involvement in various skeletal areas.
• Always search for a more specific code within the M89 category or other relevant chapters if the exact disorder is identified.
• Do not use this code if the bone development disorder is localized to a single site; instead, look for site-specific codes.
