External constriction of right index finger, init encntr

This code signifies an injury to the right index finger caused by an external object or material tightly encircling it, leading to compression. This constriction can impede blood flow, nerve function, or cause tissue damage.

Apply this code when documenting the initial treatment for a patient presenting with a right index finger constricted by an external agent, such as a ring, string, or other binding material. This includes cases where the constriction is causing pain, swelling, discoloration, or numbness.

• Ensure the documentation clearly specifies the right index finger as the affected digit.
• Verify that this is the initial encounter for this specific injury; subsequent encounters will require a different seventh character.
• Distinguish from other finger injuries like lacerations or contusions, as this code specifically denotes external constriction.
