Oth injury of blood vessel of unspecified thumb, init encntr

This code signifies an injury to a blood vessel in the thumb that is not a laceration, puncture, or contusion, and the specific vessel (artery, vein, or unspecified) is not documented. It indicates an initial assessment and treatment for such an injury where the affected thumb is not specified as right or left.

This code is appropriate for documenting initial encounters for injuries like crush injuries to the thumb resulting in hematoma or other non-lacerating vascular damage, where the exact vessel type is not specified. It is used when the injury is to the thumb, but laterality (right/left) is not recorded in the medical documentation.

• Ensure the documentation clearly states an "other specified" blood vessel injury, not a laceration, puncture, or contusion.
• Verify that the encounter is the initial treatment for this specific injury.
• Confirm that the medical record does not specify which thumb (right or left) was injured.
