M75.100 Unspecified rotator cuff tear or rupture of unspecified shoulder, not specified as traumatic

ICD-10-CM M75.100: Unspecified Rotator Cuff Tear or Rupture of Unspecified Shoulder

ICD-10-CM code M75.100 designates an unspecified rotator cuff tear or rupture of an unspecified shoulder, not specified as traumatic. This active diagnosis concept is a narrower term of M75.10. Rotator cuff tears involve shoulder pain and dysfunction, and related codes offer variants for laterality and completeness. 1 2

Plain-language overview

Code M75.100 represents an unspecified rotator cuff tear or rupture in an unspecified shoulder that is not specified as traumatic, serving as an active diagnosis concept for this medical condition. 1

What this code represents

The terminology record classifies M75.100 as a Disease or Syndrome, establishing it as a narrower concept under the parent code M75.10 for unspecified rotator cuff tear or rupture, not specified as traumatic. 1

Coding details

Code M75.100 lacks laterality and traumatic etiology specificity, whereas related codes like M75.101 specify the right shoulder within the same non-traumatic rotator cuff tear category. 1 3

The M75.1- code family includes non-traumatic rotator cuff tears, offering distinct codes for right shoulder, left shoulder, and complete or incomplete variants to capture greater clinical specificity. 4

Documentation considerations

Clinical reference materials identify distinct codes for right shoulder, left shoulder, and complete or incomplete variants within the M75.1- family, contrasting with the unspecified M75.100 code. 4

Clinical context

Rotator cuff tears are a frequent cause of shoulder pain and dysfunction, often presenting with weakness, pain during resisted arm movements, and a loss of active shoulder motion. 2

What the sources add

While the official terminology record defines the code structure and hierarchy, clinical literature provides operational context regarding the functional disability and physical presentation of rotator cuff tears. 1 2

A clinical reference list identifies the specific sibling codes within the M75.1- family, demonstrating how M75.100 contrasts with variants specifying laterality and tear completeness. 1 4
