H01.1 Noninfectious dermatoses of eyelid

ICD-10-CM Code H01.1: Noninfectious dermatoses of eyelid

ICD-10-CM code H01.1 identifies noninfectious dermatoses of the eyelid, an active diagnosis concept for the 2026 terminology cycle. It falls under the parent category H01 for other eyelid inflammation. The eyelid contains skin, fat, muscles, and glands that can be damaged by irritating substances, resulting in skin changes and potential soreness or itching. 1 6

Plain-language overview

The eyelid contains skin, fat, muscles, and glands that can be damaged by foreign bodies or irritating substances, resulting in skin changes and potential soreness or itching. 6

What this code represents

Code H01.1 represents noninfectious dermatoses of the eyelid, classified as a Disease or Syndrome semantic type with an active record status in the 2026 ICD-10-CM terminology. 1

This diagnostic concept is a narrower entity under the parent category H01, which covers other inflammations of the eyelid, and it has no narrower subordinate concepts in the terminology. 1

Coding details

The H01 category contains H01.0x codes for blepharitis subdivided by type and laterality, alongside H01.1 for noninfectious dermatoses of the eyelid, distinguishing specific condition types within the classification. 5

If clinical documentation describes only general eyelid inflammation without naming a specific condition type, H01.9 for unspecified inflammation is the correct index entry rather than H01.1. 5

Documentation considerations

Structured clinical intake rather than free-text notes can improve laterality documentation for eyelid conditions treated at skin clinics and dermatology practices. 5

Coverage and utilization context

Payer policies vary regarding eyelid inflammation codes, with some commercial payers flagging unspecified codes for additional review while others accept them when clinical notes support the absence of a confirmed diagnosis. 5

What the sources add

While terminology records establish H01.1 as an active ICD-10-CM diagnosis, clinical documentation guidelines emphasize that unspecified codes like H01.9 are only valid when the record genuinely cannot support greater specificity. 1 5

International classification sources list H01.1 alongside H01.0 for blepharitis and H01.8 for other specified eyelid inflammation, providing structural context for differentiating noninfectious dermatoses from adjacent conditions. 4
