S56.319D is a billable ICD-10 code used to specify a medical diagnosis of strain of extensor or abductor muscles, fascia and tendons of unspecified thumb at forearm level, subsequent encounter. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
S56.319D is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like strain of extensor or abductor muscles fascia and tendons of unspecified thumb at forearm level. According to ICD-10-CM Guidelines a "subsequent encounter" occurs when the patient is receiving routine care for the condition during the healing or recovery phase of treatment. Subsequent diagnosis codes are appropriate during the recovery phase, no matter how many times the patient has seen the provider for this condition. If the provider needs to adjust the patient's care plan due to a setback or other complication, the encounter becomes active again.
Unspecified diagnosis codes like S56.319D 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 following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Rupture of extensor pollicis longus
- Rupture of extensor tendon of thumb
- Rupture of tendon of thumb
- Rupture of tendon of wrist
The appropriate 7th character is to be added to each code from block Injury of muscle, fascia and tendon at forearm level (S56). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela

Types of arm injuries include :
- Tendinitis and bursitis
- Fractures (broken bones)
- Nerve problems
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.
