ICD Code M66.9

ICD code M669 refers to the spontaneous rupture of an unspecified tendon. This code is used in medical billing and documentation to indicate that a tendon in the body has ruptured without any apparent external cause or trauma, but the specific tendon affected has not been identified. This code helps healthcare providers and billing professionals categorize and communicate the nature of the injury for treatment planning and insurance purposes.
