Code Classification

  • External causes of morbidity and mortality
    (V01–Y98)

      • Exposure to other nonionizing radiation

W90.0XXA is a billable diagnosis code used to specify a medical diagnosis of exposure to radiofrequency, initial encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

W90.0XXA is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like exposure to radiofrequency. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.
