    ICD-10-CM Code For Other Inflammation Of Eyelid: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group H01 includes inflammatory disorders of the eyelid such as nonspecific eyelid inflammation, blepharitis variants not otherwise specified, and other localized eyelid inflammations. These ICD-10-CM diagnosis codes are used to document clinical encounters where eyelid inflammation is present, capturing disease location, laterality, and any specified subtypes or complications. Accurate coding within the ICD-10-CM H01 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM H01: Other Inflammation Of Eyelid Overview

    The diagnoses in the H01 group represent inflammatory conditions of the eyelid not classified elsewhere, including localized eyelid inflammation and nonspecific eyelid swelling. These conditions affect the periocular structures of the eye and can impact comfort, vision, and eyelid function. Accurate coding is important for correct claims processing and to reflect clinical complexity for reimbursement.

    When to Use

    Use a code from this group when the clinical encounter documents inflammation of the eyelid without a more specific eyelid disease classification or when the provider specifies a subtype included in the H01 codes. Select the code that reflects the documented site, laterality, and any specified etiology or complication to ensure precise coding.

    Typical Clinical Scenarios

    • An adult presents to the urgent care clinic with a rapidly painful, swollen, erythematous upper eyelid after noticing a tender lump at the lid margin for 48 hours. The patient has localized warmth, fluctuance consistent with an acute external hordeolum (stye) or acute eyelid abscess requiring incision and drainage or antibiotics; a code from this group for acute inflammation of the eyelid is assigned. Typical codes: H01.011, H01.012
    • A middle-aged patient in ophthalmology clinic has a several-month history of recurrent, non-tender chalazia and chronic granulomatous inflammation of the eyelid causing cosmetic deformity and intermittent tearing. Because this is a chronic or recurrent eyelid inflammatory condition being managed conservatively or surgically for persistent lesions, a chronic inflammation of eyelid code from this group is used. Typical codes: H01.111, H01.112
    • An elderly inpatient with poorly controlled diabetes develops cellulitis extending from the lower eyelid into the periorbital tissues after a small abrasion; the patient is admitted for IV antibiotics and monitoring for orbital spread. In this setting a code for other eyelid inflammation or diffuse eyelid cellulitis is assigned as a comorbid infectious/inflammatory process complicating the hospitalization. Typical codes: H01.021, H01.022
