How is M34.2 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to M34.2. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Sclerosis, sclerotic › systemic › drug-induced
- Sclerosis, sclerotic › systemic › due to chemicals NEC
Code first
The underlying condition below must be sequenced before M34.2. M34.2 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 M34.2 to fully describe the condition. M34.2 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 M30-M36
The conditions below can never be reported together with M34.2 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- autoimmune disease, single organ or single cell-type -code to relevant condition category
Excludes1 — never code together — inherited from M34
The conditions below can never be reported together with M34.2 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 13
The conditions below are not part of M34.2, but a patient may have both at the same time. When documentation supports it, M34.2 and the excluded code may both be reported.
- arthropathic psoriasis (L40.5-)
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- compartment syndrome (traumatic) (T79.A-)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
How long has M34.2 existed?
M34.2 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
