L89.813 Pressure ulcer of head, stage 3

Name of the Condition

• Pressure ulcer of head, stage 3

Summary

Pressure ulcer of head, stage 3, is a localized injury to the skin and underlying tissue caused by prolonged pressure. This stage involves full-thickness skin loss with visible subcutaneous fat, but bone, tendon, or muscle is not exposed. The ulcer may present with slough or eschar, and the depth varies by anatomical location (e.g., thicker tissue over the occiput may obscure deeper involvement).

Causes

The primary cause is sustained pressure that impairs blood flow to the skin and underlying tissues. Contributing factors include friction, shear forces during movement, and prolonged moisture exposure, which can weaken the skin's integrity and disrupt tissue perfusion.

Risk Factors

• Immobility or prolonged bed rest, especially in supine positions.
• Advanced age, leading to thinner skin and reduced tissue resilience.
• Poor nutrition and hydration, impairing tissue repair.
• Neurological conditions affecting sensation or mobility.
• Incontinence or excessive sweating, causing skin maceration.

Symptoms

• Persistent redness or discoloration over bony areas of the head.
• Skin that feels warmer or cooler than surrounding tissue.
• Possible pain, tenderness, or itching in the affected region.
• Open sores with visible subcutaneous fat; slough or eschar may be present.
• No exposure of bone, tendon, or muscle.

Diagnosis

Diagnosis is made through physical examination, assessing skin integrity, color, temperature, and tenderness. Staging is determined by the depth of tissue loss, with stage 3 ulcers involving full-thickness skin loss and subcutaneous fat. Documentation should include ulcer location, size, and characteristics to support staging.

Treatment Options

Treatment focuses on relieving pressure, promoting healing, and preventing infection. Interventions may include specialized support surfaces, wound dressings, debridement of necrotic tissue, and nutritional support. Antibiotics are used if infection is present.

Prognosis and Follow-Up

Prognosis depends on ulcer size, patient health, and adherence to treatment. Regular monitoring is essential to assess healing progress and adjust care plans. Follow-up may involve wound measurements, dressing changes, and reevaluation of risk factors.

Complications

• Infection (e.g., cellulitis, osteomyelitis).
• Delayed healing or chronic wounds.
• Tissue necrosis extending to deeper structures.
• Pain and reduced quality of life.

Lifestyle & Prevention

• Reposition frequently to relieve pressure on the head.
• Use protective padding over bony prominences.
• Maintain good nutrition and hydration.
• Manage moisture (e.g., incontinence care) to prevent skin maceration.
• Conduct regular skin inspections for early detection.

When to Seek Professional Help

Seek care if there are signs of infection (e.g., increased pain, redness, pus), worsening ulcer size, or failure to heal. Prompt evaluation is critical for managing complications and adjusting treatment.

Tips for Medical Coders

Document the ulcer's location (head), stage (3), and any contributing factors (e.g., immobility, incontinence) to support accurate coding. Ensure clinical notes specify full-thickness skin loss with subcutaneous fat involvement and absence of bone/tendon exposure.
