L49

Exfoliation due to erythematous conditions according to extent of body surface involved

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 10 more specific codes instead:

  • L49.0 Exfoliation due to erythematous condition involving less than 10 percent of body surface
  • L49.1 Exfoliation due to erythematous condition involving 10-19 percent of body surface
  • L49.2 Exfoliation due to erythematous condition involving 20-29 percent of body surface
  • L49.3 Exfoliation due to erythematous condition involving 30-39 percent of body surface
  • L49.4 Exfoliation due to erythematous condition involving 40-49 percent of body surface
  • L49.5 Exfoliation due to erythematous condition involving 50-59 percent of body surface
  • L49.6 Exfoliation due to erythematous condition involving 60-69 percent of body surface
  • L49.7 Exfoliation due to erythematous condition involving 70-79 percent of body surface
  • L49.8 Exfoliation due to erythematous condition involving 80-89 percent of body surface
  • L49.9 Exfoliation due to erythematous condition involving 90 or more percent of body surface

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.
