S16.1XXA – Strain of muscle, fascia and tendon at neck level, initial encounter

S16.1XXA Diagnosis Code: Strain of muscle, fascia and tendon at neck level, initial encounter

The S16.1XXA is an ICD code that’s included in the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM, for short), and it is used to designate “Strain of muscle, fascia and tendon at neck level, initial encounter.”

This ICD code pertains to the muscle, fascia, and tendons at the neck level being overstretched or torn. Strains are caused by almost the same things as sprains. In the context of the neck area, this is caused by falling, overexertion of the neck during strenuous activities, whiplash, and poor posture, to mention a few.

In this diagnosis code, “initial encounter” means that it’s the first time a patient and their condition were assessed by a certain provider. It doesn’t matter if they’ve been assessed and diagnosed with this before by another provider.

This code should also be given while the patient is actively treated for such strains.

Is S16.1XXA billable?

Yes, this ICD-10-CM code is billable and can be used to indicate a diagnosis for reimbursement.

S16.1XXA Clinical Information

To reiterate, a strain in a neck-level muscle, fascia, or tendon means that it is overstretched or in the worst case, torn. If a patient has a neck-level muscle, fascia, or tendon strain, they will likely have the following symptoms:

• Muscle spasms
• Pain in the neck, especially at the back
• Difficulty moving the neck
• Pain while moving the neck
• Headaches
• Pain that worsens over time, especially if the neck is maintained in one position for too long

The strain of neck-level muscles, fascia, or tendons is normally caused when the neck is overly twisted or pulled, whiplash due to falling or some other accident, poor posture, or strenuous activities like lifting weights or playing sports. Even sleeping awkwardly can cause strains.

The treatment for strains is non-invasive. This involves resting, using a compress (ice, cold, bandaging), and medicine to relieve the pain. Depending on the clinician treating the patient, they may implement treatment plans that involve exercise and physical therapy to rehabilitate the strain.
