Unspecified open wound, unspecified thigh, sequela

This code signifies a past open wound of the thigh, where the specific nature of the wound (e.g., laceration, puncture) and the affected thigh (left or right) are not documented. The "sequela" indicator means this code is used to report a condition that is a late effect or complication of the original wound, rather than the acute injury itself.

Use this code when a patient presents with a current condition or symptom directly resulting from a previously sustained, but now healed, open wound of the thigh. This is appropriate when the original wound details are unknown or not specified in the medical record, and the current encounter addresses a long-term consequence such as scarring, chronic pain, or functional impairment related to that past injury.

• Always sequence this code after the code for the specific sequela being treated.
• Avoid using this code for acute open wounds; those require codes from the S71.1- range without the "S" seventh character.
• Query the provider for more specific documentation regarding the original wound type and laterality if possible, to allow for more precise coding.
