S56.113 Strain of flexor muscle, fascia and tendon of right middle finger at forearm level

Name of the Condition

• Strain of flexor muscle, fascia and tendon of right middle finger at forearm level (ICD-10 Code: S56.113)

Summary

This condition involves a strain of the flexor muscle, fascia, or tendon of the right middle finger at the forearm level. It typically results from trauma, overuse, or mechanical forces affecting these soft tissues. The injury can range from mild strains to more severe tears, depending on the mechanism and force involved.

Causes

Direct trauma, such as a blow or cut to the forearm, that damages the flexor structures of the right middle finger. Repetitive or forceful movements involving the middle finger, leading to overuse injuries. Penetrating injuries, like lacerations, that disrupt the muscle, fascia, or tendon.

Risk Factors

• Participation in activities requiring repetitive middle finger use (e.g., sports, manual labor).
• Lack of proper ergonomic support during tasks involving middle finger movement.
• Previous injuries to the forearm or middle finger that weaken the structures.

Symptoms

• Pain or tenderness in the forearm near the middle finger.
• Difficulty bending or straightening the middle finger.
• Swelling or bruising at the injury site.
• Weakness in middle finger grip or pinch strength.

Diagnosis

Physical examination to assess middle finger mobility and identify tenderness or deformity. Imaging, such as ultrasound or MRI, may be used to evaluate the extent of soft tissue damage.

Treatment Options

• Rest and activity modification to avoid aggravating the injury.
• Ice application to reduce swelling and pain.
• Compression bandages or splints to support the forearm and finger.
• Physical therapy to restore strength and range of motion.
• Pain management with over-the-counter or prescription medications, as needed.

Prognosis and Follow-Up

Most strains heal with conservative treatment within a few weeks to months, depending on severity. Follow-up care may include monitoring for improvement and adjusting therapy as needed. Severe cases may require longer recovery or surgical intervention.

Complications

• Chronic pain or stiffness if the injury is not properly managed.
• Reduced finger function or grip strength.
• Re-injury due to inadequate healing or premature return to activity.

Lifestyle & Prevention

• Use ergonomic tools or techniques during repetitive tasks.
• Warm up and stretch before activities involving finger motion.
• Gradually increase activity intensity to avoid overuse.
• Wear protective gear during sports or high-risk tasks.

When to Seek Professional Help

Seek medical attention if pain is severe, mobility is significantly limited, or symptoms worsen despite home care. Immediate care is needed for open wounds, visible deformity, or signs of infection.

Tips for Medical Coders

Document the specific finger (right middle) and anatomical level (forearm) to ensure accurate coding. Include details about the mechanism of injury, clinical findings, and treatment provided to support code assignment.
