The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Skin changes due to chronic expsr to nonionizing radiation

Non-specific codes like L57 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for skin changes due to chronic expsr to nonionizing radiation:

  • Use L57.0 for Actinic keratosis - BILLABLE CODE

  • Use L57.1 for Actinic reticuloid - BILLABLE CODE

  • Use L57.2 for Cutis rhomboidalis nuchae - BILLABLE CODE

  • Use L57.4 for Cutis laxa senilis - BILLABLE CODE

  • Use L57.5 for Actinic granuloma - BILLABLE CODE

  • Use L57.8 for Other skin changes due to chronic exposure to nonionizing radiation - BILLABLE CODE

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.
