S68.52 Partial traumatic transphalangeal amputation of thumb

Name of the Condition

• Partial Traumatic Transphalangeal Amputation of Thumb

Summary

This condition describes a partial traumatic amputation of the thumb at the transphalangeal level, where only part of the thumb is lost due to injury. The amputation occurs through the bones of the thumb (phalanges) rather than at the joint connecting the thumb to the hand.

Causes

Most commonly caused by accidents involving machinery, tools, or vehicles, as well as severe trauma from falls or crush injuries. Other causes include explosions or severe burns.

Risk Factors

• Occupations involving heavy machinery or tools
• Participation in high-risk activities or sports
• Lack of protective equipment in hazardous environments

Symptoms

• Partial loss of the thumb at the transphalangeal level
• Severe pain and bleeding at the injury site
• Swelling, bruising, or exposure of bone or tendons
• Possible shock or emotional distress

Diagnosis

Based on physical examination and history of the incident. Imaging tests such as X-rays may be used to assess bone and tissue damage.

Treatment Options

• Surgical intervention: Reattachment if feasible, or preparation of the stump for prosthetics
• Rehabilitation: Physical therapy to restore function and adapt to daily activities
• Pain management: Medications as needed
• Wound care: Cleaning and dressing to prevent infection

Prognosis and Follow-Up

Prognosis depends on the severity of the amputation and the success of surgical repair. Regular follow-ups to monitor healing and functionality recovery are typically required.

Complications

• Infection at the injury site
• Nerve damage affecting sensation or movement
• Chronic pain or phantom limb sensations
• Reduced grip strength or dexterity

Lifestyle & Prevention

• Use protective equipment (e.g., gloves) in high-risk environments
• Follow safety protocols when operating machinery or tools
• Avoid activities with a high risk of hand injury when possible

When to Seek Professional Help

Seek immediate medical attention if you experience severe bleeding, exposed bone or tendons, or loss of thumb function after an injury.

Tips for Medical Coders

Document the extent of the amputation (partial vs. complete) and whether the thumb is specified (right/left) to ensure accurate coding. Include details about the mechanism of injury and any surgical interventions performed.
