    ICD-10-CM Code For Other Cataract: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group H26 includes nontraumatic and non-age-related cataracts such as congenital, secondary, and unspecified lens opacities that affect visual clarity. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving lens opacity severity, laterality, and associated ocular conditions that impact visual function. Accurate coding within the ICD-10-CM H26 group supports complete clinical documentation and appropriate reimbursement.

    ICD-10-CM H26: Other Cataract Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM H26) group for other cataract includes lens opacities and cataract conditions not classified under traumatic or age-related subgroups. These diagnoses target the ocular lens and visual system and encompass congenital, secondary, and unspecified cataracts. Accurate coding is important for complete clinical documentation and for ensuring appropriate reimbursement for ophthalmologic services.

    When to Use

    Use a code from this group when clinical documentation identifies a cataract that is not due to aging or trauma and requires specification of type or laterality. Select the most specific code to reflect whether the cataract is congenital, secondary to another condition, or unspecified.

    Typical Clinical Scenarios

    • An elderly patient presents to outpatient ophthalmology with gradually progressive, painless blurring of vision and increased glare when driving at night over several months; slit-lamp exam reveals lens opacity not consistent with nuclear sclerosis alone, and there is no history of diabetes or trauma. A diagnosis from this group is assigned to describe an age-related cataract variant involving the lens requiring characterization for surgical planning. Typical codes: H26.9, H26.30
    • A middle-aged patient with a history of long-term corticosteroid therapy for autoimmune disease reports recent decrease in visual acuity and difficulty with near tasks; examination shows posterior subcapsular lens opacities affecting the visual axis. A code from this group is assigned to specify steroid-associated cataract as the underlying lens disorder influencing management and potential referral for cataract extraction. Typical codes: H26.041, H26.049
    • A patient presents postoperatively after complicated intraocular surgery with lens changes and secondary opacification leading to reduced vision; evaluation documents traumatic or secondary cataract formation as a complication of prior ocular surgery or injury. A code from this group is used to capture the secondary/traumatic lens disorder and its laterality for billing and longitudinal records. Typical codes: H26.2, H26.211
