Other cyst of bone, left hand

This code signifies the presence of a non-specified bone cyst located in the left hand. These are benign, fluid-filled or semi-solid lesions within the bone, distinct from aneurysmal bone cysts or osteoid osteomas.

Use this code when documentation specifies a bone cyst in the left hand without further characterization of the cyst type (e.g., simple, unicameral, or aneurysmal). It is appropriate for conditions like simple bone cysts or ganglion cysts that have eroded into the bone, provided the laterality is clearly documented as left hand.

• Ensure documentation specifies "left hand" to support laterality.
• Avoid using this code if a more specific type of bone cyst (e.g., aneurysmal, solitary) is identified; use the appropriate specific code instead.
• Confirm the lesion is indeed a cyst of the bone, not a soft tissue cyst adjacent to the bone.
