Code Classification

  • External causes of morbidity and mortality
    (V01–Y99)
    • Exposure to electric current, radiation and extreme ambient air temperature and pressure
      (W85-W99)
      • Exposure to man-made visible and ultraviolet light
        (W89)

W89.9XXS is a billable diagnosis code used to specify a medical diagnosis of exposure to unspecified man-made visible and ultraviolet light, sequela. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

W89.9XXS is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like exposure to unspecified man-made visible and ultraviolet light. According to ICD-10-CM Guidelines a "sequela" code should be used for chronic or residual conditions that are complications of an initial acute disease, illness or injury. The most common sequela is pain. Usually, two diagnosis codes are needed when reporting sequela. The first code describes the nature of the sequela while the second code describes the sequela or late effect.

Unspecified diagnosis codes like W89.9XXS are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Present on Admission (POA)

W89.9XXS is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.
