Milt op involving unsp effect of nuclear weapon, milt, subs

This code signifies a subsequent encounter for a military service member who has experienced an unspecified health effect resulting from exposure to a nuclear weapon during military operations. The specific health consequences are not yet determined or documented.

This code is appropriate for follow-up visits, ongoing monitoring, or treatment for military personnel where the long-term or delayed effects of nuclear weapon exposure are being assessed or managed, but a definitive diagnosis of the specific effect has not been established. It should be used when the initial exposure occurred during military operations.

• Ensure the patient is identified as military personnel and the exposure occurred during military operations.
• Only use for subsequent encounters; an initial encounter would use the 'A' seventh character.
• Avoid if a more specific diagnosis related to nuclear weapon exposure (e.g., radiation sickness, specific cancers) can be coded.
