Other cataract (H26)

The ICD-10 code section H26 covers "Other cataract" types, including infantile, juvenile, traumatic, complicated, secondary, drug-induced, and various specified or unspecified cataracts. These codes are used to classify different cataract forms affecting one or both eyes in detailed clinical settings.

Specifically, codes under H26 help medical coders document cataracts not caused by aging alone but due to congenital conditions (infantile and juvenile cataract: H26.0 series), trauma (H26.1 series), ocular diseases (complicated cataract: H26.2), medications (drug-induced cataract: H26.3), or secondary causes following cataract surgery (secondary cataract: H26.4). Synonyms such as "presenile cataract," "traumatic cataract," "after-cataract," and "Soemmering's ring" correspond to these ICD-10 codes, aiding accurate code selection. The section also includes subtypes by eye affected; right, left, bilateral, or unspecified; and by cataract morphology like cortical, nuclear, or polar.

For example, if a patient is diagnosed with a cataract following eye trauma, the relevant ICD-10 code for traumatic cataract (H26.1 and its subcategories) should be used. Likewise, "Drug-induced cataract" (H26.3) refers to cataracts caused by medications such as corticosteroids, helping clinicians and coders capture precise etiology. This section thus supports tailored coding for diverse cataract conditions beyond age-related cataracts, optimizing clinical documentation and epidemiological tracking.

Instructional Notations

Type 1 Excludes

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.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Capsule Opacification

Clouding or loss of transparency of the posterior lens capsule, usually following CATARACT extraction.

Cataract

Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence). (Dorland, 27th ed)

Cataract Extraction

The removal of a cataractous CRYSTALLINE LENS from the eye.
