Spontaneous rupture of extensor tendons, left hand
ICD10CM code
Name of the Condition
- Spontaneous rupture of extensor tendons, left hand
- Also known as extensor tendon rupture or tendon laceration.
Summary
- This condition involves the sudden tearing or rupture of the extensor tendons located on the back of the left hand, responsible for extending the fingers and thumb. It often results in difficulty or inability to extend the affected fingers.
Causes
- The spontaneous rupture of extensor tendons can be caused by overuse of the hand, trauma, rheumatoid arthritis, or other inflammatory conditions that weaken tendon integrity.
Risk Factors
- Having rheumatoid arthritis or other forms of chronic inflammation.
- Repeated stress or overuse of the hand, common in athletes or manual laborers.
- Advanced age, which may lead to degenerative changes in tendons.
Symptoms
- Sudden onset of pain in the back of the hand.
- Inability to straighten one or more fingers or thumb.
- Swelling and possible deformity at the site of rupture.
- Visible indentation or retraction where the tendon has ruptured.
Diagnosis
- Physical examination to assess hand and finger movement.
- Ultrasound or MRI to visualize tendon rupture.
- X-rays to rule out associated fractures.
Treatment Options
- Surgical Repair: Reattachment or reconstruction of the ruptured tendon, often necessary to regain full finger movement.
- Splinting: Immobilizing the hand to protect the tendon post-surgery or in non-surgical cases.
- Physical Therapy: To restore strength and flexibility post-treatment.
Prognosis and Follow-Up
- With appropriate treatment, most individuals can expect good recovery of hand function, though full strength may take weeks to months.
- Regular follow-up is crucial to monitor healing and address any complications early.
Complications
- Permanent loss of function or dexterity in the affected fingers if not treated.
- Chronic pain or development of joint stiffness.
Lifestyle & Prevention
- Avoid repetitive hand movements or provide adequate rest and support during high-usage activities.
- Strengthening exercises to maintain tendon health.
- Proper treatment and management of underlying conditions like rheumatoid arthritis.
When to Seek Professional Help
- If sudden pain and functional loss occur in the hand, immediate medical attention is required to prevent long-term impairment.

Tips for Medical Coders
- Verify laterality for correct coding ("left hand" specifically for M66.242).
- Ensure documentation covers the absence of trauma if coding as spontaneous.
- Be aware of nuances in documentation that distinguish ruptures caused by degenerative diseases from acute injuries.
