Which MS-DRGs does G93.0 group to?

Excludes1 — never code together

The conditions below can never be reported together with G93.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • acquired periventricular cysts of newborn (P91.1)
  • congenital cerebral cysts (Q04.6)

Inclusion terms

Alternative wording in documentation that is classified to G93.0.

  • Arachnoid cyst
  • Porencephalic cyst, acquired

Excludes2 — not included here — inherited from Chapter 6

The conditions below are not part of G93.0, but a patient may have both at the same time. When documentation supports it, G93.0 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)
  • 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 G93.0 existed?

G93.0 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 G93.0?
