Osteophyte, unspecified shoulder

This code signifies the presence of an osteophyte, commonly known as a bone spur, in an unspecified shoulder joint. An osteophyte is a bony outgrowth that typically forms along joint margins, often in response to degenerative changes or stress. In the shoulder, it can contribute to impingement, pain, and restricted range of motion.

Use this code when documentation clearly indicates the presence of an osteophyte in the shoulder, but the specific shoulder (left or right) is not specified. This is appropriate for conditions like rotator cuff impingement syndrome or osteoarthritis where bone spurs are noted but laterality is not detailed. Supporting documentation would include imaging reports (X-ray, MRI) or physician notes describing the finding.

• Avoid using this code if laterality (left or right shoulder) is documented; instead, choose the more specific code.
• Frequently confused with codes for shoulder impingement without mention of an osteophyte. Ensure the documentation explicitly states "osteophyte" or "bone spur."
• Consider sequencing this code after a primary diagnosis like osteoarthritis (M19.xx) or shoulder impingement (M75.xx) if the osteophyte is a contributing factor to that condition.
