Periarthritis, unspecified wrist

This code signifies inflammation of the tissues surrounding the wrist joint, excluding the joint capsule itself. It encompasses conditions like tenosynovitis, bursitis, or other soft tissue inflammation in the wrist region, without a more specific diagnosis.

Apply this code when documentation indicates periarticular inflammation of the wrist, but a more precise diagnosis such as specific tendonitis or bursitis is not identified. This is appropriate for initial presentations or when diagnostic workup is incomplete.

• Ensure documentation explicitly states "periarthritis" or "inflammation of tissues surrounding the wrist" without further specificity.
• Avoid using this code if a more precise diagnosis, such as de Quervain's tenosynovitis (M65.43-), is documented.
• Laterality (left, right, bilateral) is not specified for this code; if known, a more specific code should be sought.
