H02.714 Chloasma of left upper eyelid and periocular area

ICD10CM code

#### Name of the Condition
- Chloasma of left upper eyelid and periocular area
- Also known as melasma or hyperpigmentation.

#### Summary
Chloasma, commonly referred to as melasma, is a skin condition characterized by dark, discolored patches on the skin. When it occurs on the left upper eyelid and periocular area, it appears as brownish or grayish spots around the eyes.

#### Causes
The exact cause of chloasma is not fully understood, but it is believed to be related to hormonal changes, sun exposure, or genetic factors. Pregnancy and oral contraceptive use are common triggers due to hormone fluctuations.

#### Risk Factors
- Female gender
- Pregnancy (often termed “the mask of pregnancy”)
- Use of oral contraceptives or hormone replacement therapy
- Frequent sun exposure
- Skin phototypes III to V (darker skin tones)
- Family history of melasma

#### Symptoms
- Brown or grayish-brown patches on the skin
- Irregular patches around the left upper eyelid and surrounding eye area
- The distribution pattern may be symmetrical

#### Diagnosis
- Clinical examination by a dermatologist
- Use of a Wood's lamp to help in evaluating pigment changes
- Occasionally, a skin biopsy is performed to rule out other conditions

#### Treatment Options
- Topical depigmenting agents (e.g., hydroquinone)
- Sun protection using broad-spectrum sunscreens
- Chemical peels and laser therapy for more persistent cases
- Lifestyle adjustments to minimize sun exposure

#### Prognosis and Follow-Up
- With consistent treatment, the appearance can improve significantly.
- Relapses can occur, especially if preventive measures are not followed.
- Regular follow-up to monitor response to treatment and adjust as necessary.

#### Complications
- Persistent hyperpigmentation despite treatment
- Psychological impact due to cosmetic concerns
- Potential worsening with inappropriate treatment or sun exposure

#### Lifestyle & Prevention
- Daily use of sunscreen with high SPF to protect against UV rays
- Wearing a wide-brimmed hat and sunglasses outdoors
- Avoiding triggers such as hormonal medications if possible

#### When to Seek Professional Help
- Rapid spread or worsening of pigmentation
- When over-the-counter treatments do not improve symptoms
- If there are changes in the appearance of patches or other worrying symptoms

#### Tips for Medical Coders
- Ensure precise documentation of the affected area (left upper eyelid and periocular area).
- Verify that the hyperpigmentation is correctly classified under the ICD code H02.714.
- Avoid coding errors by distinguishing chloasma from similar conditions like vitiligo or post-inflammatory hyperpigmentation.
