Chloasma of right eye, unsp eyelid and periocular area

This code describes a hyperpigmentation disorder, specifically chloasma (melasma), affecting the skin around the right eye, including an unspecified eyelid and the surrounding periocular region. Chloasma presents as irregular, often symmetric, brown patches on sun-exposed areas, and in this case, is localized to the right eye area.

Use this code when documentation specifies melasma or chloasma located on the right eye, without further detail regarding the specific eyelid (upper or lower). This code is appropriate when the physician's notes clearly indicate the laterality (right eye) and the general periocular involvement.

• Ensure documentation specifies "right eye" to differentiate from left (H02.712) or bilateral (H02.719) involvement.
• If the specific eyelid (upper or lower) is documented, a more precise code from the H02.71- subcategory should be used.
• This code is for the diagnosis of chloasma; do not confuse it with codes for other types of hyperpigmentation or lesions.
