Each of the codes below is billable. Choose the one that most accurately describes the patient's diagnosis.
Spontaneous (non-traumatic) rupture of a tendon that does not fall under the specifically classified extensor (M66.2), flexor (M66.3), or other named tendon categories, with no body site documented or determinable from the record.
M66.88 identifies a non-traumatic, spontaneous rupture occurring in a tendon and at a body site not captured by any more specific code within the M66.8x subcategory — a true catch-all for 'other tendons' at 'other sites.'
Spontaneous rupture of tendons at more than one anatomical site, where the tendons involved do not fall under the extensor (M66.2x) or flexor (M66.3x) classifications and the rupture occurs through normal force applied to structurally compromised tissue.
