Code Description

ICD-10 M66.811 is a billable code used to indicate a diagnosis of spontaneous rupture of other tendons, right shoulder.

Key Diagnostic Point:

Spontaneous rupture of tendons in the right shoulder is a condition characterized by the unexpected tearing of tendons without any significant trauma or injury. This condition can occur due to various factors, including degenerative changes, chronic inflammation, or underlying systemic diseases. The tendons in the shoulder, such as the rotator cuff tendons, are particularly susceptible to spontaneous rupture due to their anatomical positioning and the mechanical stresses they endure during daily activities. Patients may present with sudden onset of shoulder pain, swelling, and limited range of motion. Diagnostic imaging, such as MRI or ultrasound, is often utilized to confirm the diagnosis and assess the extent of the rupture. Treatment options may include conservative management with physical therapy and anti-inflammatory medications, or surgical intervention to repair the torn tendon, depending on the severity and impact on the patient's function. Accurate coding for this condition is essential for appropriate reimbursement and to reflect the complexity of the patient's clinical scenario.

  • Identifying the specific tendon involved
  • Understanding the patient's medical history and comorbidities
  • Documenting the clinical findings accurately

Audit Risk Factors

  • Inadequate documentation of the spontaneous nature of the rupture
  • Failure to specify the tendon involved
  • Lack of imaging studies to support the diagnosis
  • Inconsistent coding of associated conditions or procedures

Specialty Focus

Frequently Asked Questions

What is the difference between spontaneous and traumatic tendon rupture?

Spontaneous tendon rupture occurs without significant trauma, often due to degenerative changes, while traumatic rupture is a direct result of an injury or accident.
