Miltry op w nuclr radiation eff of nuclear weapon, civ, init

This code signifies an initial encounter for a civilian experiencing health effects directly attributable to nuclear radiation exposure from a military operation involving a nuclear weapon. It specifically captures the long-term or delayed consequences of such exposure, rather than acute injury from the weapon itself.

Use this code when documenting the initial diagnosis and treatment of a civilian patient presenting with conditions (e.g., specific cancers, genetic mutations, chronic illnesses) linked to past exposure to nuclear radiation from a military nuclear weapon operation. This applies to individuals who were not part of the military forces involved.

• Ensure the patient is explicitly documented as a civilian and the exposure is linked to a military nuclear weapon operation.
• This "A" initial encounter character is only for the first time the patient is seen for this specific condition. Subsequent encounters will use "D" or "S".
• Always code the specific medical condition resulting from the radiation exposure first, then use this code as an external cause code.
