Squamous blepharitis unspecified eye, unspecified eyelid

This code describes an inflammatory condition of the eyelid margins characterized by scaling and crusting, specifically due to squamous cell changes. It indicates that the affected eye and eyelid are not specified in the clinical documentation.

Use this code when the physician documents "squamous blepharitis" without specifying laterality (right or left eye) or the specific eyelid (upper or lower). This code is appropriate when the clinical record lacks further detail regarding the affected eye or eyelid.

• Avoid using this code if documentation specifies laterality (e.g., right eye, left eye) or the specific eyelid.
• Query the provider for clarification on laterality and eyelid if possible to allow for a more specific code.
• This code represents an unspecified diagnosis; strive for greater specificity when supported by documentation.
