The code S39.012A is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code S39.012A might also be used to specify conditions or terms like dislocations, sprains and strains involving multiple body regions, dislocations, sprains and strains involving thorax with lower back and pelvis, dislocations/sprains/strains, injury of muscle of lower back, injury of tendon of lower back , low back strain, etc.
S39.012A is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like strain of muscle fascia and tendon of lower back. 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.
The appropriate 7th character is to be added to each code from block Oth & unsp injuries of abd, low back, pelv & extrn genitals (S39). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela

Information for Patients
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.
