H61.113 Acquired deformity of pinna, bilateral

Name of the Condition

• Acquired deformity of pinna, bilateral

Summary

Acquired deformity of the pinna, bilateral refers to structural abnormalities of both auricles (outer ears) that develop after birth. These deformities may affect the ears' shape, size, or contour and can result from various non-congenital causes. The pinna plays a role in sound collection and protection of deeper ear structures, and acquired deformities may impact both form and function.

Causes

Acquired deformity of the pinna, bilateral can arise from trauma, inflammatory conditions, degenerative changes, or other non-congenital factors. Trauma, such as physical injury, burns, or pressure, may damage the pinna's tissues and alter its structure. Inflammatory processes, including chronic dermatitis or autoimmune reactions, can lead to scarring or tissue changes. Degenerative changes associated with aging or certain systemic conditions may also contribute to deformity. Other causes may include surgical interventions or prolonged pressure from external devices.

Risk Factors

• History of trauma or injury to both pinnae
• Chronic inflammatory skin conditions (e.g., eczema, psoriasis)
• Exposure to irritants or allergens affecting both ears
• Use of hearing aids or ear devices causing prolonged pressure on both ears
• Aging-related degenerative changes
• Previous surgical procedures involving the pinna

Symptoms

• Visible change in the shape, size, or contour of both ears
• Asymmetry or irregularities in ear structure
• Possible pain, itching, or discomfort in affected areas
• Reduced hearing or sound collection if deformity impacts function

Diagnosis

Diagnosis involves a clinical examination of both pinnae to assess structural abnormalities. A healthcare provider may evaluate the ears' shape, size, and contour, and review the patient's medical history for potential causes. Additional tests, such as imaging or skin biopsies, may be performed if underlying conditions (e.g., inflammation or trauma) are suspected.

Treatment Options

Treatment depends on the cause and severity of the deformity. Options may include conservative management (e.g., observation for mild cases), medical therapy (e.g., anti-inflammatory medications for skin conditions), or surgical intervention to correct significant structural changes. Hearing aids or devices may be recommended if function is impaired.

Prognosis and Follow-Up

Prognosis varies based on the underlying cause and treatment. Mild deformities may not require intervention, while severe cases may benefit from surgery. Follow-up appointments may be necessary to monitor for recurrence or complications, especially if caused by chronic conditions.

Complications

Potential complications include persistent pain, infection, or further tissue damage. Severe deformities may lead to functional issues, such as hearing impairment or difficulty wearing devices like glasses or headphones.

Lifestyle & Prevention

• Protect ears from trauma or injury (e.g., use protective gear during activities)
• Manage chronic skin conditions with appropriate skincare and medical treatment
• Avoid prolonged pressure from devices (e.g., adjust hearing aids or headwear)
• Seek prompt care for ear injuries or infections to prevent scarring

When to Seek Professional Help

Consult a healthcare provider if you notice changes in ear shape, size, or contour, experience pain or discomfort, or have difficulty with hearing or device use. Early evaluation can help identify underlying causes and guide appropriate management.

Tips for Medical Coders

When coding for acquired deformity of the pinna, bilateral (H61.113), ensure documentation specifies bilateral involvement and confirms the deformity is non-congenital. Verify that the condition is not related to congenital anomalies or other specific ear disorders. Accurate clinical details support correct code assignment.
