S56.126S Laceration of flexor muscle, fascia and tendon of left ring finger at forearm level, sequela

Name of the Condition

• Laceration of flexor muscle, fascia and tendon of left ring finger at forearm level, sequela (ICD-10 Code: S56.126S)

Summary

This condition represents the residual effects of a prior laceration involving the flexor muscle, fascia, and tendon of the left ring finger at the forearm level. It reflects ongoing or healed damage to these structures, which are essential for finger flexion, and may result in persistent functional impairment or anatomical changes.

Causes

The sequela arises from a previous traumatic event, such as a sharp or penetrating injury to the forearm, that lacerated the flexor structures of the left ring finger. The initial injury disrupts the muscle, fascia, or tendon, leading to long-term consequences.

Risk Factors

• Prior exposure to sharp objects or tools without protection.
• Occupations or activities involving manual labor or repetitive hand use (e.g., construction, sports).
• Inadequate safety measures during tasks with cutting hazards, increasing the likelihood of initial trauma.

Symptoms

• Persistent pain or tenderness at the forearm near the left ring finger.
• Reduced ability to bend (flex) the left ring finger.
• Swelling, scarring, or visible deformity at the injury site.
• Weakness in grip or pinch strength involving the left ring finger.

Diagnosis

Evaluation includes a physical examination to assess finger mobility, tendon function, and residual tissue damage. Imaging, such as ultrasound or MRI, may be used to document structural changes or incomplete healing.

Treatment Options

• Physical therapy to improve range of motion and strength.
• Occupational therapy for functional rehabilitation.
• Surgical intervention, if needed, to address residual tendon or tissue issues.
• Pain management strategies, including medications or modalities.

Prognosis and Follow-Up

Prognosis depends on the extent of initial injury and response to treatment. Regular follow-up ensures monitoring of functional recovery and addresses any persistent symptoms. Long-term outcomes may include partial or full restoration of finger function.

Complications

• Chronic pain or stiffness in the left ring finger.
• Tendon adhesions or limited mobility.
• Reduced grip strength or fine motor control.
• Psychological impact from persistent functional limitations.

Lifestyle & Prevention

• Use protective gear (e.g., gloves) when handling sharp objects.
• Implement safety protocols in high-risk activities or occupations.
• Engage in exercises to maintain finger flexibility and strength.
• Avoid re-injury to the affected area during recovery.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or swelling develops, or functional limitations persist despite initial treatment. Prompt evaluation is important for managing complications or adjusting therapy.

Tips for Medical Coders

Document the sequela status clearly, as this code applies to residual effects of a prior laceration. Ensure clinical notes specify the anatomical location (left ring finger, forearm level) and confirm the injury is no longer acute. Code S56.126S is used when the condition represents a sequela, not the initial injury.
