G89 is a non-billable ICD-10-CM category code for pain, not elsewhere classified, so it cannot be submitted on claims. Use a more specific code from this category instead, such as G89.0, G89.11, G89.12, and G89.18.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to G89: 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.

  • generalized pain NOS (R52)
  • pain disorders exclusively related to psychological factors (F45.41)
  • pain NOS (R52)

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.

On G89 itself
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)

  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

Patient EducationClinical

Pain

Pain is a signal in your nervous system that something may be wrong. It is an unpleasant feeling, such as a prick, tingle, sting, burn, or ache. Each person feels pain differently, even if the reason for the pain is the same. Pain may be sharp or dull. It may be mild or severe. Pain may come and go, or it may be constant.

Questions About G89Overview

What is the ICD-10 code for pain, not elsewhere classified?

G89 is the ICD-10-CM category for pain, not elsewhere classified, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is G89 (Pain, not elsewhere classified) a billable code?

No. This is a category header that groups the codes for pain, not elsewhere classified, and headers cannot be submitted on claims. Claims for pain, not elsewhere classified need a more specific code from this category, such as G89.0, G89.11, and G89.12.

Can G89 be reported with R52?

Not as a rule. The Excludes1 note on G89 lists "generalized pain NOS (R52)". 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).
