Code Classification

  • External causes of morbidity and mortality
    (V01–Y99)
    • Exposure to forces of nature
      (X30-X39)
      • Exposure to sunlight
        (X32)

X32.XXXD is a billable diagnosis code used to specify a medical diagnosis of exposure to sunlight, subsequent 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. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

X32.XXXD is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like exposure to sunlight. According to ICD-10-CM Guidelines a "subsequent encounter" occurs when the patient is receiving routine care for the condition during the healing or recovery phase of treatment. Subsequent diagnosis codes are appropriate during the recovery phase, no matter how many times the patient has seen the provider for this condition. If the provider needs to adjust the patient's care plan due to a setback or other complication, the encounter becomes active again.

Present on Admission (POA)

X32.XXXD 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.

Patient Education


Sun Exposure

Ultraviolet (UV) rays are an invisible form of radiation. They can pass through your skin and damage your skin cells. Sunburns are a sign of skin damage. Suntans aren't healthy, either. They appear after the sun's rays have already killed some cells and damaged others. UV rays can cause skin damage during any season or at any temperature. They can also cause eye problems, wrinkles, skin spots, and skin cancer.

To protect yourself :

  • Stay out of the sun when it is strongest (between 10 a.m. and 2 p.m.)
  • Use sunscreen with an SPF of 15 or higher
  • Wear protective clothing
  • Wear wraparound sunglasses that provide 100% UV ray protection
  • Avoid sunlamps and tanning beds

Check your skin regularly for changes in the size, shape, color, or feel of birthmarks, moles, and spots. Such changes are a sign of skin cancer.
