Explosion and rupture of boiler, sequela

This code indicates a health condition or injury that is a lasting consequence of an explosion and rupture of a boiler. It signifies that the patient is presenting for treatment of a chronic or residual effect directly attributable to such an incident, occurring at some point after the initial acute injury.

Apply this code when documenting conditions such as chronic pain, scarring, neurological deficits, or organ damage that are directly linked to a past boiler explosion. This is appropriate for follow-up encounters where the sequelae, rather than the initial acute injury, are the primary focus of care.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., T20.2XXA for burn scar).
• Ensure documentation clearly links the current condition to the past boiler explosion event.
• The "S" in the 7th character indicates sequela and should be used for encounters after the acute phase of injury.
