What Medicare edits apply to L49.2?

The Medicare Code Editor screens inpatient claims before they are grouped. These edits name L49.2 directly.

Cannot be a principal diagnosis — MCE edit 9

CMS will reject this code as the principal diagnosis on an inpatient claim. It describes something other than the condition chiefly responsible for the admission.

Which MS-DRGs does L49.2 group to?

L49.2 sits in MDC 09 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

How is L49.2 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to L49.2. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Exfoliation › due to erythematous conditions according to extent of body surface involved › 20-29 percent of body surface

Excludes1 — never code together — inherited from L49-L54

The conditions below can never be reported together with L49.2 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

Code first — inherited from L49

The underlying condition below must be sequenced before L49.2. L49.2 describes a manifestation and cannot be the principal or first-listed diagnosis.

  • 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)

Excludes2 — not included here — inherited from Chapter 12

The conditions below are not part of L49.2, but a patient may have both at the same time. When documentation supports it, L49.2 and the excluded code may both be reported.

  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • lipomelanotic reticulosis (I89.8)
  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
  • systemic connective tissue disorders (M30-M36)
  • viral warts (B07.-)

How long has L49.2 existed?

L49.2 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
