String or thread causing external constriction, init encntr

This diagnosis code indicates an injury resulting from a string or thread tightly constricting an external body part. This constriction can lead to various issues, including impaired circulation, tissue damage, or nerve compression, depending on the duration and tightness of the binding.

Apply this code when documenting injuries such as a finger constricted by a piece of string, a toe bound by a loose thread from clothing, or any other external body part experiencing harmful compression from a string-like object. This code is appropriate for the initial presentation of such an injury.

• Ensure the documentation clearly specifies an external constriction caused by a string or thread, not other objects.
• Verify that this is the patient's first encounter for this specific injury. Subsequent encounters would require a different seventh character.
• Always code the specific body part affected by the constriction using an additional, more specific ICD-10-CM code.
