L53.0: Toxic erythema | ICD-10-CM Code

Clinical notes

Code first

This code represents a manifestation of an underlying disease. Coding convention requires the underlying (etiology) code to be sequenced first, with this code listed second.

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

Excludes1 (not coded here)

An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).

neonatal erythema toxicum (P83.1)

Use additional code

This code represents an underlying condition. When a related manifestation is also present, coding convention calls for an additional code to be listed after this one.

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

Documentation support

General coding-documentation guidance — not a substitute for payer-specific requirements or professional coding judgment.

•Confirm the excluded condition(s) listed above are not also present — Excludes1 conditions cannot be coded together with this one.
•This code represents a manifestation. Documentation should identify the underlying condition, which must be coded first.
•If the associated manifestation or related condition noted above is also documented, an additional code should be reported alongside this one.
•As a general rule, code to the highest level of specificity supported by the documentation in the medical record.
