CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

H33 is a non-billable ICD-10-CM category code for retinal detachments and breaks, so it cannot be submitted on claims. Use a more specific code from this category instead, such as H33.001, H33.002, H33.003, and H33.009.

Specific Coding for Retinal detachments and breaksOverview

Non-specific codes like H33 require more characters. Use one of these billable codes instead:

  • H33.0 for Retinal detachment with retinal break

  • H33.00 for Unspecified retinal detachment with retinal break

  • H33.01 for Retinal detachment with single break

  • H33.02 for Retinal detachment with multiple breaks

  • H33.03 for Retinal detachment with giant retinal tear

  • H33.04 for Retinal detachment with retinal dialysis

  • H33.05 for Total retinal detachment

  • H33.1 for Retinoschisis and retinal cysts

  • H33.10 for Unspecified retinoschisis

  • H33.11 for Cyst of ora serrata

  • H33.12 for Parasitic cyst of retina

  • H33.19 for Other retinoschisis and retinal cysts

  • H33.2 for Serous retinal detachment

  • Use H33.20 for Serous retinal detachment, unspecified eye

  • Use H33.21 for Serous retinal detachment, right eye

  • Use H33.22 for Serous retinal detachment, left eye

  • Use H33.23 for Serous retinal detachment, bilateral

  • H33.3 for Retinal breaks without detachment

  • H33.30 for Unspecified retinal break

  • H33.31 for Horseshoe tear of retina without detachment

  • H33.32 for Round hole of retina without detachment

  • H33.33 for Multiple defects of retina without detachment

  • H33.4 for Traction detachment of retina

  • Use H33.40 for Traction detachment of retina, unspecified eye

  • Use H33.41 for Traction detachment of retina, right eye

  • Use H33.42 for Traction detachment of retina, left eye

  • Use H33.43 for Traction detachment of retina, bilateral

  • Use H33.8 for Other retinal detachments

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to H33: its own notes plus those printed at Chapter 7. 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 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)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • 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)
  • syphilis related eye disorders (A50.01, A50.3-, A51.43, A52.71)

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
  • Use an external cause code following the code for the eye condition, if applicable, to identify the cause of the eye condition

Use Additional Code 1

These codes say to use an additional code from the note, and H33 is one of the codes named.

Patient EducationClinical

Retinal Detachment

The retina is a layer of tissue in the back of your eye that senses light and sends images to your brain. It provides the sharp, central vision needed for reading, driving, and seeing fine detail. A retinal detachment lifts or pulls the retina from its normal position.

Questions About H33Overview

What is the ICD-10 code for retinal detachments and breaks?

H33 is the ICD-10-CM category for retinal detachments and breaks, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is H33 (Retinal detachments and breaks) a billable code?

No. This is a category header that groups the codes for retinal detachments and breaks, and headers cannot be submitted on claims. Claims for retinal detachments and breaks need a more specific code from this category, such as H33.001, H33.002, and H33.003.

Can H33 be reported with a code from H35.72?

Not as a rule. The Excludes1 note on H33 lists "detachment of retinal pigment epithelium (H35.72-, H35.73-)". 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).
