Periarthritis, right wrist

This code signifies inflammation of the tissues surrounding the right wrist joint, excluding the joint capsule itself. This condition often involves tendons, ligaments, and bursae in the periarticular region, leading to pain, swelling, and restricted movement.

Apply this code when documentation explicitly states periarthritis affecting the right wrist. This diagnosis is typically supported by physical examination findings of localized tenderness, swelling, and pain with movement around the wrist, without evidence of intrinsic joint disease.

• Ensure laterality (right) is clearly documented.
• Distinguish from arthritis (M19.-) which involves the joint itself.
• Look for documentation specifying the exact anatomical structures involved (e.g., tenosynovitis, bursitis) for more specific coding if available.
