L70.5 Acne excoriee

Name of the Condition

• Acne excoriee (L70.5)

Summary

Acne excoriee is a skin condition characterized by self-inflicted excoriations (scratches) that occur in areas of pre-existing acne or normal skin. It is often associated with psychological factors, such as anxiety or obsessive-compulsive behaviors, and typically presents with linear or irregular scratch marks. The condition may lead to secondary infections or scarring due to repeated trauma.

Causes

Acne excoriee develops when individuals compulsively pick, scratch, or manipulate their skin, often targeting areas with minor acne lesions or even normal skin. The behavior is frequently linked to underlying psychological stress, anxiety, or obsessive-compulsive tendencies. The act of scratching disrupts the skin barrier, leading to inflammation and potential secondary complications.

Risk Factors

• Psychological stress or anxiety.
• Obsessive-compulsive behaviors or disorders.
• History of skin picking or similar habits.
• Presence of mild acne or other minor skin imperfections that may trigger picking.
• Emotional distress or poor coping mechanisms.

Symptoms

• Linear or irregular scratch marks (excoriations) on the skin.
• Redness, inflammation, or crusting at the site of scratching.
• Secondary bacterial infections (e.g., impetigo) in severe cases.
• Scarring or hyperpigmentation from repeated trauma.
• Focus on areas like the face, neck, or arms, though any skin surface may be involved.

Diagnosis

Diagnosis is primarily clinical, based on the pattern of excoriations and the patient’s history of skin picking. A thorough evaluation may include assessing for underlying psychological factors or skin conditions that could contribute to the behavior. Dermatological examination helps rule out other causes of skin lesions and confirms the characteristic scratch marks.

Treatment Options

Treatment focuses on addressing both the skin damage and the underlying psychological triggers. Topical therapies, such as antibiotics or anti-inflammatory agents, may be used to manage secondary infections or inflammation. Behavioral interventions, including cognitive-behavioral therapy (CBT) or habit reversal training, are often recommended to reduce skin-picking behaviors. In some cases, psychiatric support or medications (e.g., SSRIs) may be necessary.

Prognosis and Follow-Up

Prognosis depends on the severity of the condition and the effectiveness of addressing underlying psychological factors. With appropriate treatment, skin healing and reduced picking behaviors are achievable. Follow-up care may involve regular dermatological evaluations to monitor skin health and adjust therapies as needed. Long-term management often requires ongoing psychological support.

Complications

• Secondary bacterial or fungal infections.
• Permanent scarring or hyperpigmentation.
• Worsening of pre-existing acne due to trauma.
• Emotional distress or social isolation related to skin appearance.

Lifestyle & Prevention

• Avoid picking or scratching the skin; use gentle skincare to minimize irritation.
• Manage stress through relaxation techniques, exercise, or therapy.
• Keep fingernails short to reduce skin damage if picking occurs.
• Use non-comedogenic moisturizers to maintain skin barrier integrity.
• Seek professional help for underlying anxiety or compulsive behaviors.

When to Seek Professional Help

Consult a healthcare provider if excoriations are severe, infected, or not improving with basic care. Seek help if skin picking is uncontrollable or causing significant distress. A dermatologist can assess skin damage, and a mental health professional may address psychological contributors.

Tips for Medical Coders

Document the presence of self-inflicted excoriations and any associated psychological factors (e.g., anxiety, obsessive-compulsive disorder) to support the diagnosis. Note the location and severity of lesions, as well as any secondary infections or scarring. Ensure documentation aligns with the clinical criteria for acne excoriee (L70.5) and reflects the underlying triggers or behaviors.
