M71.049 Abscess of bursa, unspecified hand

Name of the Condition

• Abscess of bursa, unspecified hand

Summary

An abscess of the bursa, unspecified hand is a localized collection of pus within a bursa in the hand, a small fluid-filled sac that reduces friction between tissues. This condition typically causes pain, swelling, and warmth at the affected site. The unspecified hand designation indicates the abscess is localized to a bursa in the hand region without specifying left or right.

Causes

Abscesses of the hand bursa usually result from bacterial infection, often introduced through direct trauma, skin breakdown, or spread from adjacent tissues. Staphylococcus aureus is a common causative organism. Non-infectious causes, such as foreign body reaction or sterile inflammation, are less frequent.

Risk Factors

• Recent injury or surgery near the hand bursa
• Skin infections or open wounds in the hand area
• Immunocompromised states (e.g., diabetes, HIV)
• Chronic inflammatory conditions (e.g., rheumatoid arthritis)
• Repetitive motion or pressure on the hand bursa

Symptoms

• Localized pain, tenderness, or throbbing in the hand
• Swelling, redness, or warmth over the bursa
• Limited range of motion in the hand or wrist
• Possible fever or systemic signs if infection spreads
• Pus drainage if the abscess ruptures

Diagnosis

Diagnosis involves a physical examination to assess bursal swelling, warmth, and tenderness. Imaging (e.g., ultrasound) may confirm the presence of fluid or pus. Aspiration of the bursa may be performed to identify the causative organism and guide treatment.

Treatment Options

Treatment typically includes antibiotics for bacterial infections and drainage of the abscess, either through needle aspiration or surgical incision. Rest, elevation, and pain management may also be recommended. Severe or recurrent cases may require surgical intervention.

Prognosis and Follow-Up

With prompt treatment, most abscesses resolve without complications. Follow-up may involve monitoring for recurrence or signs of spreading infection. Chronic or untreated abscesses can lead to persistent pain or functional impairment.

Complications

Potential complications include spread of infection to surrounding tissues, sepsis, or chronic bursitis. Delayed treatment may result in tissue damage or reduced mobility.

Lifestyle & Prevention

• Maintain good hand hygiene to reduce infection risk
• Protect the hand from trauma or excessive pressure
• Manage underlying conditions like diabetes or arthritis
• Seek prompt care for hand injuries or infections

When to Seek Professional Help

Seek medical attention if symptoms worsen, fever develops, or pus drainage occurs. Persistent pain, swelling, or limited mobility also warrants evaluation.

Tips for Medical Coders

This code (M71.049) is used for an abscess of the bursa in the unspecified hand. Documentation should specify the location (hand) and absence of left/right designation. Ensure clinical notes support the diagnosis and absence of more specific hand laterality codes.
