Explosion and rupture of unspecified gas cylinder, sequela

This code describes the long-term effects or complications arising from an injury caused by the explosion and rupture of an unspecified gas cylinder. It indicates that the initial acute injury has healed, but the patient continues to experience residual problems directly attributable to that event.

Use this code when documenting conditions such as chronic pain, scarring, neurological deficits, or organ damage that are a direct consequence of a past explosion of an unknown type of gas cylinder. This applies to follow-up encounters for these persistent issues, occurring after the initial injury has been treated.

• Always sequence this code after the code(s) for the specific sequela (e.g., scar, chronic pain syndrome).
• Ensure documentation clearly links the current condition to the past explosion of an unspecified gas cylinder.
• Do not use for initial or acute injury encounters; those require an acute injury code with an appropriate seventh character.
