Which MS-DRGs does L53.0 group to?
L53.0 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.
- 595Major Skin Disorders with MCCmedical
- 596Major Skin Disorders without MCCmedical
As a secondary diagnosis, L53.0 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
How is L53.0 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to L53.0. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Erythema, erythematous › toxic, toxicum NEC (infectional) (inflammation)
- Eruption › skin › toxic NEC
- Erythema, erythematous › due to › chemical NEC (infectional) (inflammation)
Excludes1 — never code together
The conditions below can never be reported together with L53.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- neonatal erythema toxicum (P83.1)
Code first
The underlying condition below must be sequenced before L53.0. L53.0 describes a manifestation and cannot be the principal or first-listed diagnosis.
- poisoning due to drug or toxin, if applicable (T36-T65 with fifth or sixth character 1-4)
Use additional code
Report an additional code alongside L53.0 to fully describe the condition. L53.0 is sequenced first.
- code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
Excludes1 — never code together — inherited from L49-L54
The conditions below can never be reported together with L53.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes1 — never code together — inherited from L53
The conditions below can never be reported together with L53.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 12
The conditions below are not part of L53.0, but a patient may have both at the same time. When documentation supports it, L53.0 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 L53.0 existed?
L53.0 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.
Which codes are confused with L53.0?
ICD-10-CM declares these codes mutually exclusive with L53.0 — exactly one of each pair can be correct for a given encounter.
