Localized osteoporosis [Lequesne]

This code represents a localized reduction in bone density, often affecting a specific region or joint, without evidence of systemic osteoporosis. It is characterized by bone loss in a confined area, which can lead to increased fracture risk in the affected site. This condition is also known as Lequesne's osteoporosis.

Use this code when documentation specifies localized osteoporosis, particularly when the term "Lequesne's osteoporosis" is used. It is appropriate for cases where bone density loss is confined to a specific anatomical region, such as around a joint, and is not part of a generalized osteoporotic process. Documentation should clearly indicate the localized nature of the bone density reduction.

• Do not code this with Sudeck's atrophy (M89.0) as per the Excludes1 note; these are distinct conditions.
• Ensure documentation specifies "localized" osteoporosis to differentiate from generalized forms (e.g., M81.0-M81.5).
• If the specific site of localized osteoporosis is known, consider if a more specific code within the M81 category is applicable, though M81.6 is for unspecified localized forms.
