Unspecified injury of blood vessel of right thumb, sequela

This code indicates a long-term or late effect resulting from an unspecified injury to a blood vessel in the right thumb. It signifies that the initial injury has healed, but residual symptoms or conditions related to the vascular damage persist. This could include chronic pain, altered sensation, or impaired function stemming from the original trauma.

Use this code when documenting a patient presenting with ongoing issues directly attributable to a past, unspecified blood vessel injury of the right thumb. This is appropriate for follow-up encounters where the acute phase of the injury has passed, and the current treatment addresses the lingering effects. It should be assigned when the specific type of blood vessel (e.g., artery, vein) was not documented at the time of the original injury or is unknown.

• Always sequence this code after the code for the sequela itself, if applicable.
• Ensure documentation clearly links the current condition to a previous right thumb blood vessel injury.
• If the specific blood vessel injured is known, a more specific code from the S65.4- series should be used.
