Other magnet metal obj entering via natrl orifice, sequela

This code describes the long-term effects or complications arising from a magnetic metal object that entered the body through a natural opening (e.g., mouth, nose, ear, rectum, urethra) at some point in the past. It indicates that the initial injury has resolved, but the patient is now experiencing a residual condition directly attributable to that foreign body.

Use this code when documenting a current health problem that is a direct consequence of a previously ingested, inserted, or aspirated magnetic metal object. This applies to conditions such as chronic inflammation, strictures, fistulas, or other persistent issues that developed after the acute foreign body event. Do not use for the initial encounter or acute phase of the foreign body presence.

• Always sequence this code after the code describing the specific sequela (e.g., K31.89 for other diseases of stomach and duodenum, unspecified).
• Ensure documentation clearly links the current condition to a past magnetic metal foreign body event through a natural orifice.
• This "S" seventh character indicates sequela, meaning the residual effect of a previous injury or disease.
