L53.0

L53.0 — Toxic erythema

Billable / specific codeICD-10-CM

L53.0 is a billable, specific ICD-10-CM code for toxic erythema. It is valid for submission on a claim.

Excludes1 — never code together

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

neonatal erythema toxicum (P83.1)

Code first

The underlying condition must be sequenced before this code.

poisoning due to drug or toxin, if applicable (T36-T65 with fifth or sixth character 1-4)

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)

Risk adjustment

L53.0 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.

How L53.0 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to L53.0.

Erythema, erythematous›toxic, toxicum NEC
Eruption›skin›toxic NEC
