M65.012 Abscess of tendon sheath, left shoulder

Name of the Condition

• Abscess of tendon sheath, left shoulder

Summary

Abscess of the tendon sheath in the left shoulder is a localized infection involving pus accumulation within the protective sheath surrounding the shoulder tendons. This condition can cause pain, swelling, and impaired shoulder 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 shoulder area
• Pre-existing conditions like diabetes or immune deficiencies
• Poor wound hygiene, especially after minor injuries

Symptoms

• Swelling and redness around the left shoulder tendon sheath
• Pain or tenderness, particularly with shoulder 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
• Chronic pain or reduced shoulder mobility
• Tendon damage if treatment is delayed

Lifestyle & Prevention

• Maintain good wound hygiene after shoulder injuries
• Seek prompt care for puncture wounds or infections
• Manage underlying conditions like diabetes to reduce infection risk

When to Seek Professional Help

Consult a healthcare provider if you experience persistent shoulder pain, swelling, redness, or fever, as these may indicate an abscess requiring medical intervention.

Tips for Medical Coders

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