Loose body in unspecified finger joint(s)

This code signifies the presence of a loose body, such as a cartilage fragment or bone chip, within an unspecified joint of a finger. This intra-articular foreign body can cause pain, clicking, locking, or restricted range of motion in the affected digit.

Use this code when documentation clearly indicates a loose body in a finger joint, but the specific finger (e.g., thumb, index) is not identified. This applies to cases where imaging (e.g., X-ray, MRI) or arthroscopy confirms the presence of a loose body without further anatomical specificity.

• Ensure the documentation explicitly states "unspecified finger joint" or lacks specificity regarding the digit.
• If the specific finger joint is known, a more precise code from the M24.04- subcategory should be used.
• Do not use this code if the loose body is due to a traumatic injury; instead, refer to codes in the S66- or S69- categories.
