Unspecified fracture of unspecified ischium, sequela

This code indicates a long-term complication or residual effect stemming from an unspecified fracture of the ischium, where the specific side (left or right) is not documented. It signifies that the acute phase of the fracture has passed, and the patient is now experiencing ongoing issues directly related to that past injury.

This code is appropriate for documenting conditions such as chronic pain, nonunion, malunion, or functional limitations that are a direct consequence of a previously sustained ischial fracture. It should be used when the original fracture occurred in the past and the patient is being treated for its lasting effects, and the specific ischium involved is not specified in the medical record.

• Always assign a seventh character "S" for sequela when documenting a current problem resulting from a previous injury.
• Avoid using this code for acute or initial encounters for an ischial fracture; those require different seventh characters.
• Ensure documentation clearly links the current condition to the prior ischial fracture to support the use of a sequela code.
