Crushing injury of skull, sequela

This code signifies a long-term complication or late effect resulting from a crushing injury to the skull. It indicates that the initial acute injury has resolved, but the patient continues to experience residual symptoms or conditions directly attributable to that trauma. These sequelae can include neurological deficits, chronic pain, or cosmetic deformities.

Apply this code when documentation clearly states a current condition is a direct consequence of a previously sustained crushing skull injury. This is appropriate for follow-up encounters addressing persistent issues, such as post-traumatic epilepsy, cognitive impairment, or cranial nerve palsies, that are directly linked to the original trauma. The medical record should explicitly connect the current problem to the past crushing injury.

• Always sequence this sequela code after the specific code identifying the nature of the sequela (e.g., G40.509 for post-traumatic epilepsy).
• Ensure documentation specifies "sequela," "late effect," or a similar term linking the current condition to the past injury.
• Do not use this code for acute or active crushing skull injuries; use the appropriate acute injury code (S07.1XXA, S07.1XXD) instead.
