Puncture wound without foreign body of scalp, sequela

This code describes the long-term effects or complications arising from a past puncture wound to the scalp, where no foreign object was retained. It indicates that the initial injury has healed, but residual issues related to that wound are now being addressed.

Use this code when a patient presents with a current condition that is a direct consequence of a previously sustained puncture wound to the scalp. Documentation should clearly link the current sequela (e.g., scar tissue, chronic pain, nerve damage) to the old injury. This code is appropriate when the acute phase of the original wound has passed.

• Always sequence the code for the specific sequela (e.g., scar, pain) first, followed by this sequela code.
• Ensure documentation explicitly states the current condition is a "sequela" or "due to old puncture wound" of the scalp.
• Do not use for acute puncture wounds; those require codes from the acute injury section.
