Non-billable headerICD-10-CM

L49 is a non-billable header ICD-10-CM code for exfoliation due to erythematous conditions according to extent of body surface involved. It cannot be billed on its own: choose one of the more specific child codes below.

Code first

The underlying condition must be sequenced before this code.

  • erythematous condition causing exfoliation, such as:
  • Ritter's disease (L00)
  • (Staphylococcal) scalded skin syndrome (L00)
  • Stevens-Johnson syndrome (L51.1)
  • Stevens-Johnson syndrome-toxic epidermal necrolysis overlap syndrome (L51.3)
  • Toxic epidermal necrolysis (L51.2)

Risk adjustment

L49 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead L49

10 child codes. Green means billable.
