G81 is a non-billable ICD-10-CM category code for hemiplegia and hemiparesis, so it cannot be submitted on claims. Use a more specific code from this category instead, such as G81.00, G81.01, G81.02, and G81.03.

Specific Coding for Hemiplegia and hemiparesisOverview

Non-specific codes like G81 require more characters. Use one of these billable codes instead:

  • G81.0 for Flaccid hemiplegia

  • Use G81.00 for Flaccid hemiplegia affecting unspecified side

  • Use G81.01 for Flaccid hemiplegia affecting right dominant side

  • Use G81.02 for Flaccid hemiplegia affecting left dominant side

  • Use G81.03 for Flaccid hemiplegia affecting right nondominant side

  • Use G81.04 for Flaccid hemiplegia affecting left nondominant side

  • G81.1 for Spastic hemiplegia

  • Use G81.10 for Spastic hemiplegia affecting unspecified side

  • Use G81.11 for Spastic hemiplegia affecting right dominant side

  • Use G81.12 for Spastic hemiplegia affecting left dominant side

  • Use G81.13 for Spastic hemiplegia affecting right nondominant side

  • Use G81.14 for Spastic hemiplegia affecting left nondominant side

  • G81.9 for Hemiplegia, unspecified

  • Use G81.90 for Hemiplegia, unspecified affecting unspecified side

  • Use G81.91 for Hemiplegia, unspecified affecting right dominant side

  • Use G81.92 for Hemiplegia, unspecified affecting left dominant side

  • Use G81.93 for Hemiplegia, unspecified affecting right nondominant side

  • Use G81.94 for Hemiplegia, unspecified affecting left nondominant side

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to G81: its own notes plus those printed at Chapter 6. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 6 (G00-G99) Diseases of the nervous system applies to 700 codes
  • 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)

Notes

General instructions on how these codes are used.

  • This category is to be used only when hemiplegia (complete)(incomplete) is reported without further specification, or is stated to be old or longstanding but of unspecified cause. The category is also for use in multiple coding to identify these types of hemiplegia resulting from any cause.

Patient EducationClinical

Paralysis

Paralysis is the loss of muscle function in part of your body. It happens when something goes wrong with the way messages pass between your brain and muscles. Paralysis can be complete or partial. It can occur on one or both sides of your body. It can also occur in just one area, or it can be widespread.

Questions About G81Overview

What is the ICD-10 code for hemiplegia and hemiparesis?

G81 is the ICD-10-CM category for hemiplegia and hemiparesis, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is G81 (Hemiplegia and hemiparesis) a billable code?

No. This is a category header that groups the codes for hemiplegia and hemiparesis, and headers cannot be submitted on claims. Claims for hemiplegia and hemiparesis need a more specific code from this category, such as G81.00, G81.01, and G81.02.

Can G81 be reported with a code from G80?

Not as a rule. The Excludes1 note on G81 lists "congenital cerebral palsy (G80.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
