H01.9 is a billable diagnosis code used to specify a medical diagnosis of unspecified inflammation of eyelid. The code H01.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code H01.9 might also be used to specify conditions or terms like collarettes of lash follicles, eyelash follicle finding, infection of skin of eyelid and periocular region, inflammatory lesion of eyelid or perioral dermatitis with periocular dermatitis.

Unspecified diagnosis codes like H01.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
