Perf due to fb acc left in body fol unsp procedure, sequela

This code signifies a delayed complication where a foreign object, inadvertently retained after a medical procedure, has led to a perforation of an organ or tissue. It specifically points to the sequela, meaning the long-term or late-developing consequence of the initial event. The "unspecified procedure" aspect indicates that the exact type of procedure during which the foreign body was left is not documented.

Apply this code when documentation clearly indicates a perforation resulting from a retained surgical sponge, instrument fragment, or other foreign body that was left inside a patient during a prior, unspecified medical intervention. This code is appropriate for follow-up encounters addressing the perforation itself, not the initial discovery of the retained foreign body without perforation.

• Always sequence this code after the code identifying the specific retained foreign body (e.g., T81.51xS, T81.52xS).
• Look for documentation specifying the type of perforation (e.g., bowel, bladder) and the type of retained foreign body for more specific coding if available.
• The 7th character "S" indicates a sequela, meaning this code is used for complications or conditions that arise as a direct result of the initial injury or condition, even if the original injury has healed.
