Exposure to radiofrequency, subsequent encounter

This code indicates a follow-up encounter for a patient who has previously experienced exposure to radiofrequency radiation. This could include exposure from sources such as radar, microwave ovens, or industrial radiofrequency equipment. The "subsequent encounter" designation signifies that the patient is receiving ongoing care related to the initial exposure, rather than the initial event itself.

Use this code when a patient presents for follow-up evaluation, monitoring, or treatment of symptoms or conditions that are a direct result of a past radiofrequency exposure. This would include scenarios like a patient returning for re-evaluation of burns, neurological symptoms, or other health concerns attributed to the prior exposure. It is appropriate for any visit after the initial assessment of the exposure.

• Always pair this code with an external cause code (X-code) to specify the circumstances of the radiofrequency exposure.
• Ensure an additional code is used to identify any specific health conditions or symptoms resulting from the exposure.
• The "D" seventh character indicates that this is a subsequent encounter, meaning the patient is in the healing or recovery phase.
