Sprain of tarsal ligament of unspecified foot, sequela

This code signifies a long-term complication or residual effect stemming from a sprain of the tarsal ligaments in an unspecified foot. This could include chronic pain, instability, limited range of motion, or other persistent issues that developed as a direct result of the initial sprain, even after the acute injury has healed.

This code is appropriate when documenting a patient presenting with ongoing symptoms or conditions directly attributable to a past tarsal ligament sprain, and the specific foot (left or right) is not documented or is unknown. It should be used for follow-up encounters where the sequela is being managed, rather than the initial acute injury.

• Always ensure documentation clearly links the current condition to a previous tarsal ligament sprain.
• Confirm the "S" (sequela) seventh character is appropriate, indicating a late effect rather than an active injury.
• Only use this code when the laterality of the affected foot is truly unspecified in the medical record.
