    (S00–T88)
    • Injuries to the shoulder and upper arm
      (S40-S49)
      • Injury of muscle, fascia and tendon at shoulder and upper arm level
        (S46)

S46.212 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of strain of muscle, fascia and tendon of other parts of biceps, left arm. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Strain of muscle, fascia and tendon of prt biceps, left arm

Non-specific codes like S46.212 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for strain of muscle, fascia and tendon of prt biceps, left arm:

  • Use S46.212A for initial encounter - BILLABLE CODE

  • Use S46.212D for subsequent encounter - BILLABLE CODE

  • Use S46.212S for sequela - BILLABLE CODE

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Left biceps strain
  • Rupture of hamstring tendon
  • Rupture of tendon of elbow
  • Strain of biceps brachii muscle and/or tendon
  • Tear of distal tendon of biceps brachii
  • Traumatic rupture of biceps tendon
  • Traumatic rupture of biceps tendon
  • Traumatic rupture of distal tendon of left biceps brachii
  • Traumatic rupture of left biceps femoris tendon
  • Traumatic rupture of tendon of left biceps brachii
  • Traumatic tear of hamstring tendon
  • Traumatic tear of left hamstring tendon

Coding Guidelines

The appropriate 7th character is to be added to each code from block Injury of muscle, fascia and tendon at shoulder and upper arm level (S46). Use the following options for the aplicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Patient Education


Arm Injuries and Disorders

Of the 206 bones in your body, three of them are in your arm: the humerus, radius, and ulna. Your arms are also made up of muscles, joints, tendons, and other connective tissue. Injuries to any of these parts of the arm can occur during sports, a fall, or an accident.

Types of arm injuries include :

  • Tendinitis and bursitis
  • Sprains
  • Dislocations
  • Fractures (broken bones)
  • Nerve problems
  • Osteoarthritis

You may also have problems or injure specific parts of your arm, such as your hand, wrist, elbow, or shoulder.

Sprains and Strains

A sprain is a stretched or torn ligament. Ligaments are tissues that connect bones at a joint. Falling, twisting, or getting hit can all cause a sprain. Ankle and wrist sprains are common. Symptoms include pain, swelling, bruising, and being unable to move your joint. You might feel a pop or tear when the injury happens.

A strain is a stretched or torn muscle or tendon. Tendons are tissues that connect muscle to bone. Twisting or pulling these tissues can cause a strain. Strains can happen suddenly or develop over time. Back and hamstring muscle strains are common. Many people get strains playing sports. Symptoms include pain, muscle spasms, swelling, and trouble moving the muscle.

At first, treatment of both sprains and strains usually involves resting the injured area, icing it, wearing a bandage or device that compresses the area, and medicines. Later treatment might include exercise and physical therapy.
