Short answer · Medically reviewed summary · Last updated: 2026-05-08
Paget's Disease of bone, also known as osteitis deformans, is classified under ICD-10 code M88 (with specific sub-codes for affected sites, such as M88.8 for other bones) and historically falls under ICD-9 code 731.0. These codes are essential for medical billing, clinical documentation, and tracking the prevalence of Paget's Disease within healthcare systems. What exactly is Paget's Disease? Paget's Disease is a chronic skeletal disorder characterized by excessive bone resorption followed by disorganized bone formation.

Paget's Disease is a chronic skeletal disorder characterized by excessive bone resorption followed by disorganized bone formation. This leads to enlarged, structurally weaker, and more brittle bones that are prone to deformity and fracture. While the exact etiology remains under investigation, it is believed to involve a combination of genetic predisposition and environmental triggers, such as viral infections in early life. Within the DiseaseMaps community, we have seen members navigate the unique challenges of managing the bone pain and orthopedic complications associated with Paget's Disease.
Healthcare providers use specific coding systems to ensure accurate diagnosis and treatment planning. The ICD-10 system provides greater granularity than the older ICD-9 system, allowing clinicians to specify the anatomical location of Paget's Disease, such as the skull, spine, or femur. Precise coding helps in:
Research indicates that Paget's Disease has a significant genetic component. Approximately 15% to 40% of individuals with Paget's Disease have a first-degree relative with the condition. Mutations in the SQSTM1 gene are the most commonly identified genetic factor, though the disease is considered complex rather than strictly Mendelian. Genetic counseling may be helpful for families concerned about the hereditary transmission of Paget's Disease.
