ICD-10 Code for Achilles Tendonitis

Also searched as achilles tendinitis

The ICD-10-CM code for Achilles tendonitis depends on the side: M76.61 for the right side, M76.62 for the left and M76.60 when the side is not documented. M76.6 itself is a header code and cannot be billed. There is no bilateral code, so bilateral Achilles tendonitis is reported with the right and left codes together. Valid for FY2027.

Is there an ICD-10 code for bilateral Achilles tendonitis?

No. ICD-10-CM has no bilateral code for Achilles tendonitis, so bilateral Achilles tendonitis is reported with both M76.61 (right) and M76.62 (left).

“If no bilateral code is provided and the condition is bilateral, assign separate codes for both the left and right side.”

When can the unspecified-side code for Achilles tendonitis be used?

The unspecified-side code for Achilles tendonitis is M76.60 — Achilles tendinitis, unspecified leg. M76.60 is billable.

“If the side is not identified in the medical record, assign the code for the unspecified side.”
ICD-10-CM Official Guidelines, Section I.B.13
“Codes for "unspecified" side should rarely be used, such as when the documentation in the record is insufficient to determine the affected side and it is not possible to obtain clarification.”
ICD-10-CM Official Guidelines, Section I.B.13
