Crepitant synovitis (acute) (chronic), unspecified wrist

This code signifies inflammation of the synovial membrane, characterized by a crackling or grating sensation (crepitus) upon movement, affecting an unspecified wrist. It encompasses both acute and chronic presentations of crepitant synovitis.

Use this code when documentation clearly indicates crepitant synovitis of the wrist without specifying laterality (left or right). This diagnosis is often supported by physical examination findings of crepitus, pain, and swelling in the wrist joint.

• Ensure documentation specifies "unspecified wrist" if laterality is not documented.
• If laterality is known, use the more specific codes M70.031 (right wrist) or M70.032 (left wrist).
• Differentiate from other wrist conditions like tenosynovitis (M65.84-) or other forms of synovitis without crepitus.
