Unspecified injury of diaphragm, sequela

This code signifies a long-term or late effect resulting from an unspecified injury to the diaphragm. It indicates that the original acute injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to that past diaphragmatic trauma.

This code is appropriate when documenting a current condition or symptom that is a direct consequence of a previously sustained, but now healed, diaphragmatic injury. Examples include chronic pain, respiratory compromise, or other functional limitations clearly linked to the old trauma, where the specific nature of the original injury was not documented or is unknown.

• Always sequence this sequela code after the code for the specific residual condition being treated.
• Ensure documentation clearly links the current condition to a past diaphragmatic injury.
• Avoid using this code for acute injuries; instead, use the appropriate acute injury code from the S27 category.
