Spontaneous rupture of other tendons, multiple sites

This code signifies the non-traumatic tearing of multiple tendons in various anatomical locations. It indicates a spontaneous event, meaning the rupture occurred without an external force or injury. This condition often results from underlying degenerative processes or systemic diseases weakening the tendon structure.

Apply this code when documentation clearly states a spontaneous rupture affecting more than one tendon site, such as simultaneous ruptures of the Achilles and patellar tendons. Ensure the physician's notes explicitly rule out any traumatic origin for the ruptures. This code is appropriate when the etiology points to an intrinsic tendon weakness rather than an acute injury.

• Ensure documentation specifies "spontaneous" and "multiple sites" to differentiate from traumatic ruptures or single-site involvement.
• Do not use for ruptures due to acute injury; those would fall under S-codes for specific body regions.
• Consider sequencing this code with any underlying systemic conditions (e.g., rheumatoid arthritis, corticosteroid use) that may predispose to spontaneous tendon ruptures.
