Other specified arthritis, right knee

This code signifies an inflammatory joint condition affecting the right knee that does not fit into more specific categories of arthritis. It encompasses various forms of arthritis that are not rheumatoid, osteoarthritis, traumatic, or infectious, but are clearly identified as arthritic.

Apply this code when documentation specifies arthritis of the right knee that is not otherwise classified, such as psoriatic arthritis, gouty arthritis, or other crystal arthropathies, when the specific type is known but lacks a dedicated ICD-10-CM code for the knee. Supporting documentation should clearly state "other specified arthritis" or a specific type of arthritis not found elsewhere, localized to the right knee.

• Ensure the documentation explicitly states "right knee" and a type of arthritis that is not more specifically coded elsewhere.
• Avoid using this code if a more precise ICD-10-CM code exists for the documented type of arthritis affecting the right knee (e.g., M05.xx for rheumatoid arthritis).
• Always review the medical record for laterality and the specific type of arthritis to prevent miscoding with unspecified arthritis (M13.961) or arthritis of other specified sites.
