Spontaneous rupture of flexor tendons, multiple sites

This code signifies the non-traumatic tearing of flexor tendons affecting multiple anatomical locations. This condition typically arises from underlying degenerative processes, inflammatory conditions, or systemic diseases rather than an acute injury.

Apply this code when documentation clearly indicates spontaneous (non-traumatic) rupture of flexor tendons in more than one distinct anatomical site. Supporting documentation should detail the affected tendons and explicitly state the absence of an acute external force or injury.

• Ensure documentation specifies "spontaneous" and "multiple sites" for flexor tendons; otherwise, a more specific code for a single site or traumatic rupture may be appropriate.
• Distinguish from traumatic ruptures (S-codes) and other forms of tendonitis or tenosynovitis without rupture.
• Sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity impacting treatment.
