ICD-10-CM Code W90.0XXA

Exposure to radiofrequency, initial encounter

Version 2020 Billable Code

Valid for Submission

W90.0XXA is a billable code used to specify a medical diagnosis of exposure to radiofrequency, initial encounter. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code W90.0XXA might also be used to specify conditions or terms like overexposure to radar radiation or overexposure to radiation or overexposure to radioactive isotopes or overexposure to radiofrequency radiation or overexposure to radiopharmaceuticals.

Short Description:Exposure to radiofrequency, initial encounter
Long Description:Exposure to radiofrequency, initial encounter


The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Overexposure to radar radiation
  • Overexposure to radiation
  • Overexposure to radioactive isotopes
  • Overexposure to radiofrequency radiation
  • Overexposure to radiopharmaceuticals

Convert W90.0XXA to ICD-9

  • E926.0 - Radiofreq radiat exposur (Approximate Flag)

Code Classification

  • External causes of morbidity and mortality (V01–Y98)
    • Exposure to electric current, radiation and extreme ambient air temperature and pressure (W85-W99)
      • Exposure to other nonionizing radiation (W90)

Information for Patients

Electromagnetic Fields

Electric and magnetic fields (EMFs), also called radiation, are areas of energy that surround electrical devices. Everyday sources of EMFs include

  • Power lines
  • Electrical wiring
  • Microwave ovens
  • Computers
  • Cell phones

Some people worry about EMF exposure and cancer. Some studies have found a link between EMF exposure and a higher risk of childhood leukemia, but other studies have not. Other studies have not found proof that EMF exposure causes other childhood cancers. Studies in adults did not prove that EMF exposure causes cancer.

Some people worry that cell (wireless) phones cause cancer or other health problems. The phones do give off radiofrequency energy (RF), a form of electromagnetic radiation. So far, scientific evidence has not found a link between cell phone use and health problems in humans. However, scientists need to do more research on this before they can say for sure. If you are worried about avoiding any possible risks, you can limit your exposure by

  • Reducing the amount of time you spend using your cell phone
  • Use speaker mode or a headset to place more distance between your head and the cell phone
