Osteitis deformans without mention of bone tumor
  • Billable Code
  • Short description: Osteitis deformans NOS.
  • ICD-9-CM 731.0 will be replaced by an equivalent ICD-10-CM code (or codes) when the United States transitions from ICD-9-CM to ICD-10-CM on October 1, 2015.
  • ICD-9-CM 731.0 is a billable medical code that can be used to specify a diagnosis on a reimbursement claim.

Clinical Information
  • A disease of bone that initially results in the excessive resorption of bone (by osteoclasts) followed by the replacement of normal bone marrow with vascular and fibrous tissue.
  • Disease marked by repeated episodes of increased bone resorption followed by excessive repair, resulting in weakened, deformed bones of increased mass.
Applies To
  • Paget's disease of bone

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 731.0 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
