S33.6XXA diagnosis code: Sprain of sacroiliac joint, initial encounter

The ICD-10-CM code S33.6XXA denotes a sprain of the sacroiliac joint during an initial encounter. This code applies when a patient presents for the first time with an acute injury involving the sacroiliac joint, which connects the lumbar spine to the pelvis. Such sprains may result from trauma, overuse, or sudden movements affecting the pelvic joints and surrounding ligaments.

Yes, S33.6XXA is a billable ICD-10-CM code used for reimbursement purposes. It is appropriate for documenting a sacroiliac joint sprain's initial evaluation and treatment.

Clinical information

• A sprain of the sacroiliac joint involves overstretching or tearing of the joints and ligaments that connect the sacrum to the ilium in the pelvis.
• It may occur alongside other injuries such as a pelvis sprain, pelvis laceration, or trauma to the lumbar spine and pelvis.
• Common causes include pelvis traumatic subluxation, pelvis traumatic rupture, or pelvis traumatic tear resulting from falls, accidents, or sudden twisting motions.
• Symptoms may encompass pain in the lower back, buttocks, or hip, which can radiate to the groin or upper thighs, and may worsen with standing or walking.
• Diagnosis typically involves physical examinations and imaging studies to assess the lumbar spine and pelvic joints, and to rule out more severe injuries involving muscle, bone, or neurological compromise.
• Treatment options include rest, ice application, physical therapy, and in some cases, interventions for associated conditions like pelvis traumatic hemarthrosis.​
