S62.164S Nondisplaced fracture of pisiform, right wrist, sequela

Name of the Condition

• Nondisplaced fracture of pisiform, right wrist, sequela

Summary

This condition refers to a healed or healing nondisplaced fracture of the pisiform bone in the right wrist, with residual effects or complications following the initial injury. The pisiform is a small, pea-shaped carpal bone on the palmar (palm) side of the wrist, embedded within the flexor carpi ulnaris tendon. Sequela indicates the presence of long-term consequences from the prior fracture, such as persistent pain, limited mobility, or other chronic changes.

Causes

The sequela arises from a previous nondisplaced fracture of the pisiform bone in the right wrist, typically resulting from trauma like a fall onto an outstretched hand, a direct blow to the palmar wrist, or a crushing injury. The residual effects develop as the bone heals, potentially leading to ongoing functional or structural changes.

Risk Factors

• Prior wrist trauma or fracture history.
• Inadequate healing or rehabilitation after the initial injury.
• Underlying conditions affecting bone or soft tissue recovery (e.g., poor circulation, certain metabolic disorders).

Symptoms

• Chronic pain or discomfort in the palmar side of the right wrist.
• Reduced range of motion or stiffness in the wrist or hand.
• Persistent swelling or tenderness at the injury site.
• Possible weakness or altered grip strength.

Diagnosis

Evaluation includes a detailed patient history to confirm prior fracture and assess residual symptoms. Physical examination focuses on wrist mobility, pain patterns, and functional limitations. Imaging (e.g., X-rays, CT scans) may be used to assess bone healing and identify any structural abnormalities contributing to sequela.

Treatment Options

Management depends on symptom severity and functional impact. Options may include:

• Physical therapy to improve mobility and strength.
• Pain management with medications or modalities (e.g., heat, cold).
• Orthotic devices or splints for support.
• Surgical intervention if significant functional impairment or deformity is present.

Prognosis and Follow-Up

Prognosis varies based on the extent of residual effects and response to treatment. Regular follow-up ensures symptom management and monitors for complications. Most patients experience improved function with appropriate care, though some may have persistent limitations.

Complications

• Chronic pain or arthritis in the wrist.
• Persistent stiffness or reduced mobility.
• Nerve or tendon irritation from scar tissue or bone changes.
• Increased risk of future wrist injuries due to altered mechanics.

Lifestyle & Prevention

• Avoid repetitive or high-impact wrist activities to reduce strain.
• Use ergonomic tools or supports during daily tasks.
• Engage in exercises to maintain wrist strength and flexibility (as advised by a healthcare provider).
• Wear protective gear during sports or activities with fall risks.

When to Seek Professional Help

Consult a healthcare provider if:

• Symptoms worsen or new issues (e.g., increased pain, swelling) develop.
• Daily activities or mobility are significantly impaired.
• Signs of infection (e.g., redness, warmth, fever) appear at the wrist.

Tips for Medical Coders

Document the sequela status clearly, including the history of the prior fracture and any residual effects. Ensure clinical notes specify the chronic nature of the condition and its impact on function. Code S62.164S is appropriate for nondisplaced pisiform fractures of the right wrist with sequela; verify alignment with the patient’s current clinical presentation and prior injury documentation.
