About the H25–H28 Code Range
ICD-10 codes H25 through H28 cover a wide range of disorders affecting the lens of the eye, primarily various types of cataracts and other lens abnormalities. These codes specify conditions by cataract type, cause, laterality, and additional lens disorders such as aphakia and lens dislocation.
This chapter includes age-related cataracts (H25.x), which feature subtypes like cortical, nuclear, morgnagnian (hypermature), and combined forms. Synonyms such as "cortical senile cataract" or "brunescent cataract" help clarify coding for specific cataract variants in right, left, or both eyes. The H26 series addresses other cataracts including infantile and juvenile cataracts, traumatic cataracts, complicated cataracts, and drug-induced cataracts, with options to specify eye involvement. Codes under H27 include aphakia (absence of the lens), lens dislocation, both anterior and posterior, and other specified lens disorders, many with synonyms like "phacodonesis" (lens tremulousness) or "lens particle glaucoma." Finally, H28 codes cover cataracts that occur with systemic diseases or due to external causes like nutritional deficiencies. This detailed classification supports precise medical coding for lens conditions, aiding accurate documentation of eye diseases by type, cause, and eye laterality.
