- Non-Billable Category
- Chronic Condition
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.

Coding notes and annotation back-references applicable to this code.
Code First
Type 1 Excludes
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Retinal Disorders
The retina is a layer of tissue in the back of your eye that senses light and sends images to your brain. In the center of this nerve tissue is the macula. It provides the sharp, central vision needed for reading, driving and seeing fine detail.

Questions About H36Overview
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.
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.
