Unspecified injury of popliteal vein, right leg, subs encntr

This code indicates an unspecified injury to the popliteal vein in the right leg, meaning the exact nature of the trauma (e.g., laceration, contusion) is not documented. It is used when a patient is receiving follow-up care for this injury after the initial treatment phase.

This code is appropriate for patients presenting for subsequent care, such as wound checks, follow-up imaging, or physical therapy, related to an unspecific right popliteal vein injury. It should be used after the initial encounter for the injury has been coded. Examples include a patient returning for a scheduled re-evaluation of a right leg deep vein injury sustained in a fall, where the specific type of injury was not initially determined.

• Ensure the documentation clearly states "right leg" and "popliteal vein" for accurate site specificity.
• Verify that the encounter is for follow-up care, not the initial treatment, to justify the "D" seventh character.
• If the specific type of popliteal vein injury is later identified, a more specific code should be used for subsequent encounters.
