Unsp opn wnd right lesser toe(s) w damage to nail, sequela

This code signifies a long-term consequence or late effect of an open wound on one or more of the right lesser toes, where the injury specifically involved damage to the toenail. The initial wound itself is not specified, meaning its exact nature (e.g., laceration, puncture) is unknown, but its lasting impact on the toe and nail is being documented.

Use this code when documenting a patient presenting with a chronic condition or complication directly resulting from a past, unspecified open wound to the right lesser toes that involved nail damage. This would apply to follow-up encounters for issues like chronic nail deformity, persistent infection, or other long-term sequelae stemming from the original injury.

• Always sequence this code after the code for the primary condition or sequela being treated.
• Ensure documentation clearly states the injury is to the "right lesser toe(s)" and explicitly mentions "damage to nail" as a sequela.
• If the specific type of open wound is known, a more specific code from the S91.2 series should be used instead.
