Which MS-DRGs does G04.1 group to?

G04.1 sits in MDC 01 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.

  • 052Spinal Disorders and Injuries with CC/MCCmedical
  • 053Spinal Disorders and Injuries without CC/MCCmedical

As a secondary diagnosis, G04.1 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

How is G04.1 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to G04.1. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Paraplegia › tropical spastic (lower)
  • Paraplegia › spastic › tropical (lower)

Excludes1 — never code together — inherited from G04

The conditions below can never be reported together with G04.1 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 6

The conditions below are not part of G04.1, but a patient may have both at the same time. When documentation supports it, G04.1 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 G04

The conditions below are not part of G04.1, but a patient may have both at the same time. When documentation supports it, G04.1 and the excluded code may both be reported.

  • acute transverse myelitis (G37.3)
  • alcoholic encephalopathy (G31.2)
  • multiple sclerosis (G35-)
  • myalgic encephalomyelitis (G93.32)
  • subacute necrotizing myelitis (G37.4)
  • toxic encephalitis (G92.8)
  • toxic encephalopathy (G92.8)

How long has G04.1 existed?

G04.1 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.
