Nontraumatic, spontaneous rupture of one or more extensor tendons at a body site that is not specified in the clinical documentation.
Nontraumatic rupture of an extensor tendon at a body site not captured by the more specific M66.2x codes — most commonly applied to the wrist when a site-specific wrist code does not fully describe the location.
M66.29 captures spontaneous rupture of extensor tendons occurring at more than one anatomical site simultaneously, where no external traumatic force caused the failure — the tendons themselves are inferred to have subnormal structural integrity.
