S62.146S Nondisplaced fracture of body of hamate [unciform] bone, unspecified wrist, sequela

Name of the Condition

• Nondisplaced fracture of body of hamate [unciform] bone, unspecified wrist, sequela

Summary

This condition refers to a previous nondisplaced fracture of the body of the hamate bone (a small carpal bone on the ulnar side of the wrist) that has entered a sequela phase. A sequela indicates residual effects or complications following the initial injury, where the fracture has healed but may result in ongoing functional or structural changes. The hamate contributes to wrist stability and grip, and sequela-related issues may include persistent pain, limited mobility, or other long-term consequences of the healed fracture.

Causes

The sequela arises from a prior nondisplaced fracture of the hamate bone, typically caused by direct trauma such as a fall onto an outstretched hand, a blow to the wrist, or a crushing injury. The residual effects are a result of the initial injury and its healing process.

Risk Factors

• History of wrist trauma or fracture.
• Inadequate initial treatment or healing of the fracture.
• Underlying conditions affecting bone or soft tissue recovery (e.g., poor circulation, diabetes).

Symptoms

• Persistent pain or discomfort in the ulnar side of the wrist.
• Reduced range of motion or stiffness in the wrist or hand.
• Weakness in grip strength.
• Possible swelling or tenderness at the injury site.
• Altered sensation or nerve-related symptoms if adjacent structures were affected.

Diagnosis

Evaluation includes a review of the patient’s medical history, focusing on the initial fracture and its treatment. Physical examination assesses wrist function, pain, and mobility. Imaging, such as X-rays or MRIs, may be used to identify residual bone changes, malalignment, or associated complications from the healed fracture.

Treatment Options

Management focuses on addressing residual symptoms and improving function. Options may include physical therapy to restore mobility and strength, pain management strategies, or adaptive devices to support daily activities. In some cases, further evaluation for surgical intervention may be considered if structural issues persist.

Prognosis and Follow-Up

Prognosis depends on the extent of residual effects and the patient’s response to treatment. Regular follow-up appointments monitor functional improvement and address ongoing symptoms. Long-term outcomes may vary, with some patients experiencing full recovery and others having persistent limitations.

Complications

• Chronic pain or discomfort.
• Persistent wrist stiffness or reduced mobility.
• Nerve compression or irritation.
• Arthritis or degenerative changes in the wrist over time.

Lifestyle & Prevention

• Avoid repetitive or high-impact wrist activities that may exacerbate symptoms.
• Use ergonomic supports or braces during activities to reduce strain.
• Engage in prescribed physical therapy to maintain or improve wrist function.
• Protect the wrist from further injury through proper safety measures.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or swelling develops, or functional limitations interfere with daily activities. Prompt evaluation is important if signs of infection, increased pain, or neurological symptoms (e.g., numbness, tingling) occur.

Tips for Medical Coders

This code (S62.146S) is used for a sequela of a nondisplaced hamate bone fracture. Documentation should clearly indicate the prior fracture and its residual effects. Ensure the sequela is linked to the original injury and that the fracture is confirmed as healed with ongoing complications. Avoid using this code for acute fractures or initial encounters.
