Explosion of explosive gases, sequela

This code signifies the long-term or residual effects resulting from an injury caused by the explosion of explosive gases. These sequelae are conditions that arise as a direct consequence of the initial blast, manifesting after the acute phase of the injury has passed. Examples include chronic pain, scarring, neurological deficits, or hearing loss directly attributable to the gas explosion.

Use this code when documenting a patient presenting with a current condition that is a direct, late effect of an injury sustained from an explosion of explosive gases. This applies when the acute injury has healed, but its lasting impact is still present and requires ongoing treatment or management. It should be assigned for follow-up encounters addressing these chronic complications.

• Always sequence this sequela code after the code for the specific nature of the sequela (e.g., T90.5XXA for sequela of intracranial injury).
• Ensure documentation clearly links the current condition to the past explosion of explosive gases.
• Do not use for acute injuries; this code is exclusively for late effects.
