Spontaneous rupture of flexor tendons, thigh
ICD-10 M66.35 is a billable code used to indicate a diagnosis of spontaneous rupture of flexor tendons, thigh.
Spontaneous rupture of flexor tendons in the thigh is a rare but significant condition that typically occurs without any preceding trauma or identifiable cause. This condition is characterized by the sudden tearing of the flexor tendons, which are responsible for bending the knee and controlling movement in the thigh. The rupture can lead to acute pain, swelling, and loss of function in the affected limb. Patients may present with a palpable defect in the tendon, and diagnostic imaging, such as MRI or ultrasound, may be utilized to confirm the diagnosis. The underlying mechanisms may involve degenerative changes, inflammatory processes, or systemic conditions that weaken the tendon structure. Treatment often requires surgical intervention to repair the ruptured tendon, followed by rehabilitation to restore function and strength. Understanding the nuances of this condition is crucial for accurate coding and appropriate management.
Detailed operative reports, imaging studies, and post-operative notes are essential for accurate coding.
Patients presenting with acute knee pain and swelling, often after minimal or no trauma.
Documentation must clearly indicate the spontaneous nature of the rupture and any underlying conditions.
Comprehensive assessments of functional limitations and rehabilitation progress.
Patients undergoing rehabilitation post-surgery for tendon repair.
Focus on documenting functional outcomes and therapy interventions.
Used when surgical repair is performed for spontaneous tendon rupture.
Operative report detailing the procedure and findings.
Orthopedic surgeons must document the nature of the rupture and the surgical approach.
The primary cause is often related to degenerative changes in the tendon, which can be exacerbated by systemic conditions such as rheumatoid arthritis or diabetes.
