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

H36 is a non-billable ICD-10-CM category code for retinal disorders in diseases classified elsewhere, so it cannot be submitted on claims. Use a more specific code from this category instead, such as H36.811, H36.812, H36.813, and H36.819. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Retinal and vitreous conditions.

Specific Coding for Retinal disorders in diseases classified elsewhereOverview

Non-specific codes like H36 require more characters. Use one of these billable codes instead:

  • H36.8 for Other retinal disorders in diseases classified elsewhere

  • H36.81 for Nonproliferative sickle-cell retinopathy

  • H36.82 for Proliferative sickle-cell retinopathy

  • Use H36.89 for Other retinal disorders in diseases classified elsewhere

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to H36: 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)

Code First

The underlying condition named in the note is sequenced before this code.

  • underlying disease, such as:
  • lipid storage disorders (E75.-)
  • sickle-cell disorders (D57.-)

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

Patient EducationClinical

Retinal Disorders

Retinal disorders are conditions that affect the retina, the thin light-sensitive tissue at the back of your eye. The retina senses light and sends signals to your brain so you can see.

Questions About H36Overview

What is the ICD-10 code for retinal disorders in diseases classified elsewhere?

H36 is the ICD-10-CM category for retinal disorders in diseases classified elsewhere, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is H36 (Retinal disorders in diseases classified elsewhere) a billable code?

No. This is a category header that groups the codes for retinal disorders in diseases classified elsewhere, and headers cannot be submitted on claims. Claims for retinal disorders in diseases classified elsewhere need a more specific code from this category, such as H36.811, H36.812, and H36.813.

Can H36 be reported with a code from H35.0?

Not as a rule. The Excludes1 note on H36 lists "arteriosclerotic retinopathy (H35.0-)". 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).

What is coded first with H36?

The Code First note reads: underlying disease, such as: lipid storage disorders (E75.-); sickle-cell disorders (D57.-). When one of these applies, it is sequenced before H36.

What is the ICD-9 equivalent of H36?

Under the General Equivalence Mappings, retinal disorders in diseases classified elsewhere converts to ICD-9-CM 362.71 (ret dystrph in lipidoses) and 362.72 (ret dystrph in syst dis). The mapping is approximate, so confirm the match fits the documentation.
