S62.613P Displaced fracture of proximal phalanx of left middle finger, subsequent encounter for fracture with malunion

Name of the Condition

• Displaced fracture of proximal phalanx of left middle finger, subsequent encounter for fracture with malunion (ICD-10 Code: S62.613P)

Summary

A displaced fracture of the proximal phalanx of the left middle finger, subsequent encounter for fracture with malunion, refers to a bone break where the fragments are no longer in their normal alignment, and the healing process has resulted in improper bone union. This condition affects the first bone segment of the middle finger, which connects to the hand, and the malunion indicates the bone has healed in a non-anatomical position. The "subsequent encounter" specifies this is a follow-up visit for a fracture that has already been treated, and "malunion" denotes the abnormal healing outcome.

Causes

Direct trauma or impact to the finger, such as from falls, sports injuries, or accidents. Crushing injuries or severe bending forces applied to the finger can also cause this type of fracture. Malunion may occur if the initial fracture was not properly aligned during treatment or if healing was compromised.

Risk Factors

• Participation in contact sports or activities with a high risk of hand injuries.
• Occupations involving manual labor or handling heavy equipment.
• Prior history of hand or finger fractures.
• Osteoporosis or other conditions that weaken bone density.
• Inadequate immobilization or non-compliance with treatment during initial fracture care.

Symptoms

• Persistent pain or discomfort in the affected finger.
• Swelling or stiffness around the injury site.
• Visible deformity or misalignment of the finger.
• Reduced range of motion or difficulty moving the finger.
• Possible numbness or tingling if nerves are involved.
• Functional limitations in daily activities requiring hand use.

Diagnosis

Physical examination by a healthcare professional to assess pain, swelling, and mobility. Imaging tests, such as X-rays, to confirm malunion and evaluate the extent of bone misalignment. Comparison with prior imaging may be used to assess healing progress.

Treatment Options

• Orthopedic referral for evaluation of malunion severity.
• Physical therapy to improve range of motion and strength.
• Pain management with medications or modalities.
• Surgical intervention (e.g., osteotomy) in severe cases to realign the bone.
• Occupational therapy to assist with functional recovery.

Prognosis and Follow-Up

Prognosis depends on the degree of malunion and functional impact. Most patients experience improved symptoms with treatment, though some residual stiffness or deformity may persist. Regular follow-up visits are necessary to monitor healing and adjust treatment plans. Long-term outcomes may include mild functional limitations, depending on the severity of the malunion.

Complications

• Chronic pain or discomfort.
• Reduced finger mobility or stiffness.
• Nerve damage leading to numbness or weakness.
• Arthritis in the affected joint over time.
• Aesthetic concerns due to visible deformity.
• Increased risk of future fractures in the same area.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Avoid repetitive or forceful hand movements that strain the finger.
• Maintain bone health through proper nutrition and exercise.
• Follow post-fracture care instructions to ensure proper healing.
• Seek early evaluation for finger injuries to prevent malunion.

When to Seek Professional Help

• Persistent or worsening pain, swelling, or deformity.
• Inability to move the finger or perform daily tasks.
• Numbness, tingling, or changes in skin color.
• Signs of infection (e.g., redness, warmth, drainage) at the injury site.
• Concerns about improper healing or malunion.

Tips for Medical Coders

Document the presence of malunion and the subsequent encounter status clearly in the medical record. Ensure the fracture is specified as displaced and involving the proximal phalanx of the left middle finger. Include details about the healing status and any functional limitations to support the code assignment. Verify that the encounter is classified as "subsequent" and not initial or acute.
