S46.101A is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like unspecified injury of muscle fascia and tendon of long head of biceps right arm. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.
Unspecified diagnosis codes like S46.101A are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
The appropriate 7th character is to be added to each code from block Injury of muscle, fascia and tendon at shldr/up arm (S46). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela

Information for Patients
Shoulder Injuries and Disorders
Your shoulder joint is composed of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone). Your shoulders are the most movable joints in your body. They can also be unstable because the ball of the upper arm is larger than the shoulder socket that holds it. To remain in a stable or normal position, the shoulder must be anchored by muscles, tendons, and ligaments.
Because your shoulder can be unstable, it can be easily injured. Common problems include
- Sprains and strains
- Torn rotator cuffs
- Frozen shoulder
Health care providers diagnose shoulder problems by using your medical history, a physical exam, and imaging tests.
Often, the first treatment for shoulder problems is RICE. This stands for Rest, Ice, Compression, and Elevation. Other treatments include exercise and medicines to reduce pain and swelling. If those don't work, you may need surgery.
