Other batteries entering via natural orifice, sequela

This code signifies the long-term or residual effects resulting from a battery, other than a button battery, having entered the body through a natural opening. These sequelae can manifest after the initial acute injury has resolved, indicating ongoing health issues directly attributable to the foreign body ingestion or insertion.

Apply this code when documenting conditions such as strictures, perforations, chronic inflammation, or other lasting damage to the gastrointestinal tract, respiratory system, or other affected areas, that are a direct consequence of a non-button battery foreign body event. This code is appropriate for follow-up encounters where the initial injury has passed the acute phase but its impact persists.

• Always use in conjunction with a code identifying the specific sequela (e.g., K22.2 for esophageal obstruction).
• Ensure the medical record clearly links the current condition to a past event involving a non-button battery.
• Distinguish carefully from acute foreign body encounters, which use different codes.
