Which MS-DRGs does G40.C01 group to?

G40.C01 sits in MDC 01 and helps define the logic of 1 MS-DRG (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 023Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis with MCC or Antineoplastic Implant or Epilepsy with Neurostimulatorsurgical

As a secondary diagnosis, G40.C01 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

How is G40.C01 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to G40.C01. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Epilepsy, epileptic, epilepsiamyoclonus, myoclonicprogressiveLaforanot intractablewith status epilepticus (attack) (cerebral) (convulsion) (fit) (seizure)

Excludes1 — never code together — inherited from G40

The conditions below can never be reported together with G40.C01 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • conversion disorder with seizures (F44.5)
  • convulsions NOS (R56.9)
  • post traumatic seizures (R56.1)
  • seizure (convulsive) NOS (R56.9)
  • seizure of newborn (P90)

Excludes2 — not included here — inherited from Chapter 6

The conditions below are not part of G40.C01, but a patient may have both at the same time. When documentation supports it, G40.C01 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)

Excludes2 — not included here — inherited from G40

The conditions below are not part of G40.C01, but a patient may have both at the same time. When documentation supports it, G40.C01 and the excluded code may both be reported.

Code also — inherited from G40.C

Two codes may be needed to describe the condition fully. Whether G40.C01 is sequenced first depends on the reason for the encounter.

  • , if applicable, associated conditions such as dementia (F02.8-)

How long has G40.C01 existed?

G40.C01 first appears in FY2024.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
