Contusion of unspecified thigh, sequela

This diagnosis code indicates a bruise or contusion of an unspecified thigh, where the injury itself is no longer acute but has left a residual effect or complication. This could include persistent pain, scarring, muscle weakness, or other long-term issues stemming from the original trauma.

Apply this code when documenting follow-up care for a patient who previously sustained a thigh contusion and is now presenting with a sequela related to that past injury. This is appropriate when the initial acute injury has resolved, but ongoing treatment or evaluation is necessary for its lasting effects.

• Always use in conjunction with a code describing the specific sequela (e.g., chronic pain, scar, muscle weakness).
• Ensure documentation clearly states the thigh contusion is a past injury and the current encounter addresses a residual condition.
• Do not use for acute contusions; refer to the appropriate acute injury code for initial encounters.
