H05 is a non-billable ICD-10-CM category code for disorders of orbit, so it cannot be submitted on claims. Use a more specific code from this category instead, such as H05.00, H05.011, H05.012, and H05.013.

Instructional NotesGuidance

Excludes1

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

  • congenital malformation of orbit (Q10.7)

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 Block H00-H05 Disorders of eyelid, lacrimal system and orbit applies to 574 codes
From Chapter 7 (H00-H59) Diseases of the eye and adnexa applies to 2,677 codes
  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)

  • congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
  • diabetes mellitus related eye conditions (E09.3-, E10.3-, E11.3-, E13.3-)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury (trauma) of eye and orbit (S05.-)
  • 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.

From Chapter 7 (H00-H59) Diseases of the eye and adnexa applies to 2,677 codes

Eye Diseases

Even if your eyes feel healthy, you could have a problem and not know it. That's why regular eye exams are so important. Refractive errors are the most common type of vision problem that makes it hard to see clearly. But some eye conditions or diseases don't have any symptoms and can lead to a permanent loss of vision.

  • What diseases can affect the eye?
  • What are the symptoms of eye diseases?
  • Who is more likely to develop eye diseases?
  • What are the treatments for eye diseases?
  • Can eye diseases be prevented?

Questions About H05Overview

What is the ICD-10 code for disorders of orbit?

H05 is the ICD-10-CM category for disorders of orbit, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is H05 (Disorders of orbit) a billable code?

No. This is a category header that groups the codes for disorders of orbit, and headers cannot be submitted on claims. Claims for disorders of orbit need a more specific code from this category, such as H05.00, H05.011, and H05.012.

Can H05 be reported with Q10.7?

Not as a rule. The Excludes1 note on H05 lists "congenital malformation of orbit (Q10.7)". 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).
