S56.125 Laceration of flexor muscle, fascia and tendon of right ring finger at forearm level

Name of the Condition

• Laceration of flexor muscle, fascia and tendon of right ring finger at forearm level (ICD-10 Code: S56.125)

Summary

This condition involves a cut or tear in the flexor muscle, fascia, and tendon of the right ring finger at the forearm level. The injury disrupts the soft tissues responsible for finger flexion, potentially impairing movement and function. It may range from partial to complete laceration, depending on the severity of the trauma.

Causes

Direct trauma, such as a sharp or penetrating injury to the forearm, that lacerates the flexor structures of the right ring finger. This can include cuts from tools, glass, or other objects that damage the muscle, fascia, or tendon.

Risk Factors

• Handling sharp objects or tools without proper protection.
• Occupations or activities involving manual labor or repetitive hand use (e.g., construction, cooking, sports).
• Lack of safety measures during tasks with cutting hazards.

Symptoms

• Pain or tenderness at the forearm near the right ring finger.
• Difficulty bending (flexing) the right ring finger.
• Swelling, bruising, or visible laceration at the injury site.
• Weakness in grip or pinch strength involving the right ring finger.

Diagnosis

Physical examination to assess finger mobility, tendon function, and wound characteristics. Imaging, such as ultrasound or MRI, may be used to evaluate tendon integrity and guide treatment planning.

Treatment Options

• Wound cleaning and debridement to prevent infection.
• Surgical repair of the lacerated structures, if necessary.
• Immobilization with a splint or cast to allow healing.
• Physical therapy to restore finger movement and strength.

Prognosis and Follow-Up

Prognosis depends on the extent of the laceration and timely treatment. Full recovery is possible with appropriate care, but delayed or inadequate treatment may lead to long-term functional impairment. Follow-up appointments monitor healing and rehabilitation progress.

Complications

• Infection at the injury site.
• Tendon adhesion or scarring, limiting finger movement.
• Chronic pain or weakness.
• Nerve damage affecting sensation or motor function.

Lifestyle & Prevention

• Use protective gear (e.g., gloves) when handling sharp objects.
• Practice proper safety protocols in high-risk occupations or activities.
• Avoid repetitive or forceful hand movements that strain the flexor tendons.

When to Seek Professional Help

Seek immediate medical attention for deep lacerations, inability to bend the finger, severe pain, or signs of infection (e.g., redness, pus, fever).

Tips for Medical Coders

Document the specific finger (right ring finger) and anatomical level (forearm) to ensure accurate coding. Include details about the extent of the laceration (partial vs. complete) and any associated injuries for comprehensive coding.
