Superficial foreign body of unsp part of head, sequela

This code signifies the long-term effects or complications arising from a superficial foreign body embedded in an unspecified area of the head. It indicates that the acute phase of the foreign body presence has passed, and the patient is now experiencing a residual condition directly attributable to that past event.

Use this code when documenting a sequela (e.g., scarring, chronic pain, nerve damage, infection) resulting from a superficial foreign body that was previously located in the head, and the specific anatomical site within the head is not documented. Documentation should clearly link the current condition to the prior foreign body and specify that it is a sequela.

• Always assign an additional code to specify the nature of the sequela (e.g., L90.5 for scar conditions, G89.29 for other chronic pain).
• Ensure documentation explicitly states "sequela" or describes a residual condition directly linked to a past superficial foreign body of the head.
• Do not use for current, active foreign body presence; refer to codes without the "S" (sequela) seventh character for acute encounters.
