Exposure to laser radiation, sequela

This code signifies a long-term or late effect resulting from a previous exposure to laser radiation. It is used when the initial injury or condition caused by the laser has healed, but residual problems or complications persist. This could include chronic pain, vision impairment, scarring, or other lasting tissue damage.

Apply this code when documenting a patient's current condition that is a direct consequence of a past laser exposure, and the acute phase of the injury has resolved. Examples include a patient presenting with persistent visual disturbances years after an accidental laser pointer exposure, or chronic skin discoloration following a therapeutic laser treatment.

• Always sequence this code after the code describing the specific sequela (e.g., H53.8 for other visual disturbances).
• Ensure documentation clearly links the current condition to a prior laser exposure.
• Do not use for acute laser injuries; those require codes from the T20-T32 range for burns or T33-T34 for corrosions, or other specific injury codes.
