M65.022 Abscess of tendon sheath, left upper arm

Name of the Condition

• Abscess of tendon sheath, left upper arm

Summary

Abscess of the tendon sheath in the left upper arm is a localized infection characterized by pus accumulation within the protective sheath surrounding the tendons of the left upper arm. This condition can cause pain, swelling, and impaired movement if not treated promptly.

Causes

Bacterial infections are the primary cause, often resulting from trauma, puncture wounds, or the spread of infection from other body areas. Less commonly, it may arise from systemic infections.

Risk Factors

• Recent injuries or penetrative wounds to the left upper arm
• Pre-existing conditions like diabetes or immune deficiencies
• Poor wound hygiene, especially after minor injuries

Symptoms

• Swelling and redness around the left upper arm tendon sheath
• Pain or tenderness, particularly with movement
• Warmth in the affected area
• Possible fever or chills indicating systemic infection

Diagnosis

Diagnosis involves a physical examination to assess tenderness, swelling, and movement limitations. Blood tests may identify infectious agents, and imaging studies like MRI or ultrasound can confirm abscess presence.

Treatment Options

• Antibiotic therapy to address bacterial infection
• Surgical intervention may be necessary to drain the abscess

Prognosis and Follow-Up

With timely treatment, most cases resolve without long-term issues. Follow-up care ensures infection resolution and monitors for recurrence.

Complications

• Spread of infection to surrounding tissues or bloodstream
• Tendon damage or restricted movement
• Chronic pain or functional impairment if untreated

Lifestyle & Prevention

• Clean and properly care for any wounds to the left upper arm
• Manage underlying conditions like diabetes to reduce infection risk
• Avoid activities that may cause trauma to the left upper arm

When to Seek Professional Help

Seek medical attention if you experience persistent pain, swelling, redness, or fever in the left upper arm, as these may indicate an abscess requiring prompt treatment.

Tips for Medical Coders

Document the specific location (left upper arm) and confirm the diagnosis of an abscess of the tendon sheath. Ensure clinical notes support the site and nature of the infection for accurate coding.
