Diseases of the Eye and Adnexa
This month’s focus is “Understanding the ICD-10-CM Draft Guidelines for Diseases of the Eye and Adnexa.”
Diseases of the Eye and Adnexa is located in chapter seven of ICD-10-CM. Laterality for most of the categories in chapter seven designates codes for right eye, left eye, and bilateral (both eyes). When a code does designate which eye is involved, that condition is considered bilateral. Conversely, when a bilateral code is not provided the condition is considered unilateral.
