Enthesopathies, lower limb, excluding foot (M76)

This group of ICD-10 codes, M76, categorizes disorders known as enthesopathies affecting the lower limb but excluding the foot. These codes specifically address conditions involving inflammation or degeneration where tendons and ligaments attach to the bone, such as tendinitis and bursitis of various tendons around the hip, thigh, and knee.

The ICD-10 code for enthesopathies of the lower limb serves to classify common conditions like gluteal tendinitis (M76.0), psoas tendinitis (M76.1), and Achilles tendinitis (M76.6), among others. Synonyms such as "Tendinitis of right gluteal tendon" or "Calcific tendinitis of Achilles tendon" help health professionals accurately pinpoint diagnoses. Also included are bursitis forms like tibial collateral bursitis (Pellegrini-Stieda syndrome) (M76.4) and syndromes such as iliotibial band syndrome (M76.3). Detailed subcodes specify the exact location, including right or left limb involvement, improving coding precision and clinical documentation. These codes are essential for coding enthesopathies affecting areas like the hip and knee but exclude foot enthesopathies, useful for both medical coding specialists and healthcare providers evaluating musculoskeletal complaints.

Instructional Notations

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

  • bursitis due to use, overuse and pressure M70
  • enthesopathies of ankle and foot M77.5

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Iliotibial Band Syndrome

An overuse injury causing lateral knee pain that results from repetitive friction of the iliotibial band over the lateral femoral epicondyle.
