Polyosteoarthritis (M15)

ICD-10 code M15 covers various types of polyosteoarthritis, a condition involving osteoarthritis affecting multiple joints. These codes help specify whether the osteoarthritis is primary, involves specific finger joint deformities like Heberden's nodes (M15.1) or Bouchard's nodes (M15.2), or represents other forms such as erosive or secondary arthritis.

The ICD-10 code for polyosteoarthritis includes subcodes that clarify the cause and presentation. For example, M15.0 is used for primary generalized osteoarthritis, also called idiopathic osteoarthritis, without a known secondary cause. M15.1 identifies Heberden's nodes, which are bony swellings at the end finger joints, while M15.2 notes Bouchard's nodes, swelling in the middle finger joints. The code M15.3 applies to secondary multiple arthritis, emerging due to another disease. Erosive osteoarthritis, characterized by joint erosions, is coded as M15.4. For other or unspecified forms affecting several joints, M15.8 and M15.9 are used. These codes guide accurate documentation when coding for degenerative joint disease involving multiple joints and aid healthcare professionals in recording precise clinical diagnoses.
