Osteophyte, left knee

This code describes the presence of an osteophyte, commonly known as a bone spur, specifically located in the left knee joint. An osteophyte is a bony outgrowth that forms along joint margins, often in response to joint damage or degeneration.

This code is used when documentation clearly indicates the presence of an osteophyte affecting the left knee. This often occurs in the context of osteoarthritis or other degenerative joint conditions. Supporting documentation would include imaging reports (e.g., X-ray, MRI) or physician notes explicitly stating "osteophyte, left knee."

• Always specify laterality (left, right, bilateral) when documented.
• Do not code an osteophyte as a standalone diagnosis if it is an integral part of a more specific condition like osteoarthritis, unless the osteophyte itself is the primary reason for the encounter.
• Review documentation carefully to determine if the osteophyte is symptomatic or incidental, as this may influence sequencing with other knee diagnoses.
