    ICD-10-CM Code For Age-Related Cataract: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group H25 includes age-related cataracts and related senile lens opacities that result in progressive visual impairment and may be categorized by morphology and laterality. These ICD-10-CM diagnosis codes are used to document clinical scenarios such as unilateral or bilateral lens opacification, complications related to cataract progression, and preoperative assessment for cataract extraction, capturing disease severity, organ involvement, or clinical complexity relevant to this group. Accurate coding within the ICD-10-CM H25 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM H25: Age-related cataract Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM H25) code group covers age-related changes to the crystalline lens of the eye that lead to lens opacity and visual impairment. These diagnoses target the ocular lens within the visual system and include types and stages of senile or age-associated cataract. Accurate coding matters for complete clinical documentation and for appropriate reimbursement tied to the documented severity and laterality of the cataract.

    When to Use

    Use a code from this group when clinical documentation identifies an age-related lens opacity or cataract, including specified laterality and type. Codes in this group are also used to document preoperative status or complications directly attributable to the age-related cataract.

    Typical Clinical Scenarios

    • An 78-year-old patient presents to the ophthalmology clinic with progressively blurred central vision over several months, trouble reading, and increased glare at night. Slit-lamp exam shows nuclear lens opacification without signs of secondary cataract or inflammation; visual acuity is reduced but stable aside from the gradual decline. A code from this group is assigned to document an age-related nuclear cataract as the primary diagnosis for preoperative planning or monitoring. Typical codes: H25.11, H25.12
    • A 68-year-old diabetic patient arrives to the emergency eye clinic after acute vision deterioration in one eye following minor head trauma. Examination reveals a mature cortical-to-nuclear mixed lens opacity with sudden worsening of vision consistent with accelerated age-related cataract progression; no intraocular infection is identified. A code from this group is used to capture the acute exacerbation of an existing age-related cataract affecting care decisions. Typical codes: H25.13, H25.23
    • An 82-year-old patient with advanced age-related posterior subcapsular cataract is being evaluated preoperatively for cataract extraction and intraocular lens implantation; the chart also notes complicated lens changes and decreased visual function impacting activities of daily living. A specific code from the group is assigned to document the posterior subcapsular morphology and laterality for surgical scheduling and outcomes tracking. Typical codes: H25.041, H25.042, H25.049
