I69.059 — Hemiplegia and hemiparesis following nontraumatic subarachnoid hemorrhage affecting unspecified side

BillableUnspecifiedCC

Is I69.059 billable?

Yes, but I69.059 will trip a Medicare edit. I69.059 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists I69.059 under Medicare Code Editor edit 20, “Unspecified code” — meaning a code specifying laterality (right, left or bilateral) exists in the same family. On an inpatient claim this triggers the edit, because CMS holds that there are very limited circumstances in which laterality cannot be documented.

What Medicare edits apply to I69.059?

The Medicare Code Editor screens inpatient claims before they are grouped. These edits name I69.059 directly.

Unspecified — a laterality-specific code exists — MCE edit 20

A code specifying laterality (right, left or bilateral) exists in the same family. CMS holds that there are very limited circumstances in which laterality cannot be documented.

Which MS-DRGs does I69.059 group to?

I69.059 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.

  • 056Degenerative Nervous System Disorders with MCCmedical
  • 057Degenerative Nervous System Disorders without MCCmedical

As a secondary diagnosis, I69.059 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

How is I69.059 listed in the Alphabetic Index?

The Alphabetic Index lists these routes under I69.05, the nearest indexed parent of I69.059. Use them to find the family, then select the specific code.

Excludes1 — never code together — inherited from I60-I69

The conditions below can never be reported together with I69.059 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • traumatic intracranial hemorrhage (S06.-)

Excludes1 — never code together — inherited from I69

The conditions below can never be reported together with I69.059 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • personal history of cerebral infarction without residual deficit (Z86.73)
  • personal history of prolonged reversible ischemic neurologic deficit (PRIND) (Z86.73)
  • personal history of reversible ischemic neurologcial deficit (RIND) (Z86.73)
  • sequelae of traumatic intracranial injury (S06.-)

Use additional code — inherited from I60-I69

Report an additional code alongside I69.059 to fully describe the condition. I69.059 is sequenced first.

  • code to identify presence of:
  • alcohol abuse and dependence (F10.-)
  • exposure to environmental tobacco smoke (Z77.22)
  • history of tobacco dependence (Z87.891)
  • hypertension (I10-I1A)
  • occupational exposure to environmental tobacco smoke (Z57.31)
  • tobacco dependence (F17.-)
  • tobacco use (Z72.0)

Excludes2 — not included here — inherited from Chapter 9

The conditions below are not part of I69.059, but a patient may have both at the same time. When documentation supports it, I69.059 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)
  • systemic connective tissue disorders (M30-M36)
  • transient cerebral ischemic attacks and related syndromes (G45.-)

How long has I69.059 existed?

I69.059 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.
