W90.2 is the authoritative medical code for Exposure to laser radiation. This classification is used in medical billing and clinical recording to specify the clinical criteria for exposure to laser radiation (ICD-10-CM W90.2), ensuring healthcare documentation aligns with 2026 federal coding standards.
Billing Status: NO. This is a clinician non-billable / parent hierarchy grouping in the ICD-10-CM system.
Official Registry Overview & Definition
Exposure to laser radiation is a non-billable ICD-10-CM category code W90.2. A more specific billable subcode must be selected for claims submission. Excludes1 (not coded here): exposure to:; failure in dosage of radiation or temperature during surgical and medical care Y63.2-Y63.5; lightning T75.0-; natural cold X31; natural heat X30; natural radiation NOS X39; radiological procedure and radiotherapy Y84.2; sunlight X32. Excludes2 (not included here): exposure to sunlight X32. 7th character: The appropriate 7th character is to be added to each code from category W90.

Frequently Asked Questions (FAQ) & Clinical Guidance
Can W90.2 be billed directly?
No. W90.2 (Exposure to laser radiation) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
Does W90.2 require a 7th character?
Yes. The appropriate 7th character is to be added to each code from category W90.
What can't be coded together with W90.2?
Per Excludes1 instructions, W90.2 must not be reported with: exposure to:; failure in dosage of radiation or temperature during surgical and medical care (Y63.2-Y63.5); lightning (T75.0-); natural cold (X31).
Can W90.2 be reported alongside related conditions?
Per Excludes2 instructions, W90.2 and the following may both be reported when both are present: exposure to sunlight (X32).
