Battery unspecified, entering via natural orifice, sequela

This code signifies a long-term complication or residual effect resulting from an unspecified battery that entered the body through a natural opening. This could include issues like strictures, perforations, or chronic inflammation that developed after the initial battery ingestion or insertion.

Apply this code when documenting a patient presenting with a current health problem directly attributable to a past event where an unspecified battery entered a natural orifice. This is appropriate for follow-up care or when the sequela is the primary reason for the encounter, and the acute phase of the battery exposure has resolved.

• Always use an additional code to specify the exact nature of the sequela (e.g., K22.2 for esophageal obstruction).
• Ensure documentation clearly links the current condition to the past battery exposure.
• This code is for sequelae, not for the initial acute event of battery ingestion/insertion.
