Which MS-DRGs does M30.8 group to?
M30.8 sits in MDC 08 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 545Connective Tissue Disorders with MCCmedical
- 546Connective Tissue Disorders with CCmedical
- 547Connective Tissue Disorders without CC/MCCmedical
As a secondary diagnosis, M30.8 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
How is M30.8 listed in the Alphabetic Index?

Excludes1 — never code together — inherited from M30-M36
The conditions below can never be reported together with M30.8 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 M30
The conditions below can never be reported together with M30.8 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- microscopic polyarteritis (M31.7)
Excludes2 — not included here — inherited from Chapter 13
The conditions below are not part of M30.8, but a patient may have both at the same time. When documentation supports it, M30.8 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 M30.8 existed?
M30.8 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 M30.8?
ICD-10-CM declares these codes mutually exclusive with M30.8 — exactly one of each pair can be correct for a given encounter.
