Injury of muscle, fascia and tendon at shoulder and upper arm level (S46) ICD-10-CM

The S46 code range covers injury of muscle, fascia and tendon at shoulder and upper arm level with 319 ICD-10-CM diagnosis codes. 216 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.

Code Also

A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.

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.

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

7th Character

Indicates that a seventh character is to be assigned to codes in a subcategory.

Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the S46 range.

Rotator Cuff Tear Arthropathy

Rapidly destructive shoulder joint and bone disease found mainly in elderly, and predominantly in women. It is characterized by SHOULDER PAIN; JOINT INSTABILITY; and the presence of crystalline CALCIUM PHOSPHATES in the SYNOVIAL FLUID. It is associated with ROTATOR CUFF INJURIES.

About the S46 Code Range

ICD-10 code S46 covers injuries to muscles, fascia, and tendons specifically at the shoulder and upper arm level, including the rotator cuff, biceps, triceps, and other related muscles. These codes are used to classify a wide range of injuries such as strains, lacerations, and unspecified or other injuries affecting these structures. They are detailed further by specific muscle groups and by right, left, or unspecified arm locations, with extensions indicating initial, subsequent, or sequela encounters.

The ICD-10 coding for the shoulder and upper arm includes detailed categories to capture injuries to the rotator cuff (e.g., S46.0 and subcodes like S46.001 for right rotator cuff injury), injuries to the long head of the biceps (e.g., S46.1 with specific codes like S46.111 for right arm strain), as well as other parts of the biceps, triceps, or other muscles at this level. Synonyms such as "injury of right rotator cuff," "traumatic tear of tendon," "rupture of tendon of right shoulder," and "laceration of right biceps brachii muscle" correspond to specific codes to clarify coding choices. These detailed codes help medical coders precisely document injuries based on location, type (strain, laceration, etc.), and stage of care, which is vital when using the ICD-10 code for shoulder and upper arm muscle, fascia, and tendon injuries.

Questions About This Page

How many billable codes are in the S46 range?

What does the S46 range classify?

The range classifies injury of muscle, fascia and tendon at shoulder and upper arm level. Each code links to its own reference page with billing status, MS-DRG grouping, coding notes, and clinical information.
