What ICD-10 Codes are Used for Knee Osteoarthritis?
Osteoarthritis (OA) is a degenerative joint disorder involving wear and tear of cartilage. The knee, being a major weight-bearing joint, is often affected. The ICD-10-CM system provides specific codes to document the knee's severity and site of OA.
Here are some commonly used ICD-10-CM codes for knee osteoarthritis:
- M17.0: Bilateral primary osteoarthritis of knee
Both knees are affected, and the cause is primarily degenerative, without an identifiable initiating factor.
- M17.1: Unilateral primary osteoarthritis of knee
Only one knee is affected by primary osteoarthritis.
- M17.10: Unilateral primary osteoarthritis, unspecified knee
One knee is affected, but it's unspecified which one.
- M17.11: Unilateral primary osteoarthritis, right knee
Only the right knee is affected.
- M17.12: Unilateral primary osteoarthritis, left knee
Only the left knee is affected.
- M17.2: Bilateral post-traumatic osteoarthritis of knee
Both knees have OA resulting from an injury.
- M17.3: Unilateral post-traumatic osteoarthritis of knee
One knee has OA resulting from an injury.
