Blepharochalasis right upper eyelid

This code signifies a diagnosis of blepharochalasis affecting the right upper eyelid. Blepharochalasis is a rare, recurrent, non-inflammatory edema of the eyelids, leading to stretching and atrophy of the eyelid skin, often resulting in redundant folds.

Apply this code when documentation specifically indicates blepharochalasis impacting the right upper eyelid. This diagnosis is typically supported by clinical examination findings describing episodic eyelid swelling and subsequent thinning and wrinkling of the skin.

• Ensure the documentation specifies "right upper eyelid" to accurately assign this laterality and location.
• Differentiate from dermatochalasis (H02.81-) which is age-related redundant eyelid skin, not episodic edema.
• Consider co-reporting with codes for associated conditions, such as thyroid ophthalmopathy, if documented as causative.
