L93: Lupus erythematosus

Non-billable headerICD-10-CM

L93 is a non-billable header ICD-10-CM code for lupus erythematosus. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • lupus exedens (A18.4)
  • lupus vulgaris (A18.4)
  • scleroderma (M34.-)
  • systemic lupus erythematosus (M32.-)

Use additional code

Add a secondary code to capture the detail described below.

  • code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
