About coding achilles tendon injury

The ICD-10-CM code for achilles tendon injury is S86.00 (Unspecified injury of Achilles tendon). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S86.00.

Within S86.0, choose S86.00 (Unspecified injury of Achilles tendon) only when documentation doesn't support a more specific option: strain of Achilles tendon (S86.01), laceration of Achilles tendon (S86.02) and other specified injury of Achilles tendon (S86.09).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
