Traumatic rupture of collateral ligament of unsp wrist, init

This code signifies an acute, non-degenerative tear of a collateral ligament within the wrist joint, resulting from a recent injury. The specific collateral ligament (radial or ulnar) is not documented, and the affected wrist (left or right) is also unspecified.

Apply this code for a patient presenting with a new wrist injury, where clinical examination or imaging (e.g., MRI) confirms a collateral ligament rupture. This code is appropriate when the exact ligament and laterality are not yet determined or documented, and it's the first time the patient is being treated for this specific injury.

• Ensure documentation clearly states "initial encounter" for the injury.
• Avoid using this code if the specific collateral ligament (radial or ulnar) or laterality (left/right) is known; instead, use a more specific code.
• Do not use for chronic or recurrent ruptures; look for codes indicating subsequent or sequela encounters.
