Partial thickness tears of the supraspinatus muscle are an incomplete disruption of muscle fibers; note that these can progress to a complete or full thickness tear of the supraspinatus muscle, and larger tears pose a higher risk of progression to full tears, even if they are asymptomatic.
A supraspinatus tear is a tear or rupture of the tendon of the supraspinatus muscle. The supraspinatus is part of the rotator cuff of the shoulder. Most of the time it is accompanied with another rotator cuff muscle tear.
726.13 - Partial tear of rotator cuff is a topic covered in the ICD-10-CM.
"M75. 102 - Unspecified Rotator Cuff Tear or Rupture of Left Shoulder, Not Specified as Traumatic." ICD-10-CM, 10th ed., Centers for Medicare and Medicaid Services and the National Center for Health Statistics, 2018.
A traumatic rotator cuff diagnosis is defined as an injury of the rotator cuff ligaments, muscles, and tendons and maps to rotator cuff sprain/strain and/or tear/rupture. ICD-10 codes S46. 011A (right shoulder) and S46. 012A (left shoulder) are for strain/tear/rupture OR S43.
A partial tear of the rotator cuff is when the tendon is damaged but not completely ruptured (torn); a full thickness tear is where the tendon has torn completely through, often where it is attached to the top of the upper arm (humerus), making a hole in the tendon.
The names of these muscle-tendon components of the rotator cuff are: the supraspinatus which runs over the top of the ball of the shoulder joint (humeral head); the subscapularis which runs across the front of the humeral head; and. the infraspinatus and the teres minor which run across the back of the humeral head.
A partial tear goes only part of the way into the tendon. It's usually described in terms of how deep the tear is in the tendon and doesn't refer to length, width or other dimensions. A full-thickness tear is when the wear in the tendon goes all the way through the tendon.

Supraspinatus tear can be caused by lifting something too heavy, falling on your arm, or dislocating your shoulder. However, host cases are the result of the tendon wearing down over time, which is known as a degenerative tear.
Partial tears: Also called incomplete tears, the damage experienced by the tendon does not sever it completely. Complete tears: More commonly referred to as a full-thickness tear, this injury entirely separates the tendon from the bone.
The term "subscapularis" means under (sub) the scapula (wingbone). It is part of the four rotator cuff muscles, the other three are the supraspinatus, infraspinatus and teres minor muscles. The subscapularis is the largest and strongest muscle of the rotator cuff.
