Oth complications of surgical and medical care, NEC, sequela

This code identifies long-term or late effects resulting from surgical or medical care that are not specifically classified elsewhere in ICD-10-CM. These are conditions that arise as a consequence of an earlier acute complication or adverse event related to a procedure or treatment, and are now considered a permanent or chronic issue.

Apply this code when documenting a sequela (late effect) of a surgical or medical complication that is not covered by more specific codes. Examples include chronic pain syndromes post-procedure where the initial complication is resolved, or persistent functional deficits directly attributable to a past adverse event from medical care. This code is used when the original complication is no longer active but its lasting impact is being treated.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure the documentation clearly links the current condition to a past complication of surgical or medical care.
• Do not use for active, acute complications; those require codes from the T80-T88 range without the "S" seventh character.
