Overview of CPT Code 23490:Arthroscopy, shoulder, surgical; with rotator cuff repair
CPT Code 23490 refers to a surgical procedure performed via arthroscopy to repair a torn rotator cuff in the shoulder. This minimally invasive technique allows for the assessment and treatment of shoulder injuries, particularly those affecting the rotator cuff, which is crucial for shoulder stability and movement.
When CPT Code 23490 is Used?
This procedure is indicated in various clinical scenarios, including:
- Significant rotator cuff tears that cause pain and limit shoulder function.
- Chronic shoulder pain not relieved by conservative treatments.
- Acute injuries resulting in rotator cuff tears.
- Shoulder instability associated with rotator cuff damage.
Symptoms Indicating This Procedure
Patients may report the following symptoms that suggest the need for this procedure:
- Persistent shoulder pain, especially during overhead activities.
- Weakness in the shoulder or arm.
- Limited range of motion in the shoulder joint.
- Pain that worsens at night or with specific movements.
Causes and Risk Factors
Several factors can contribute to the development of rotator cuff tears, including:
- Age-related degeneration of the rotator cuff tendons.
- Acute injuries from falls or accidents.
- Repetitive overhead activities, such as in athletes or manual laborers.
- Previous shoulder injuries or surgeries.
Diagnostic Tests Before Procedure
To confirm the diagnosis and assess the extent of the injury, the following tests may be performed:
- MRI of the shoulder to visualize soft tissue structures.
- Ultrasound to assess rotator cuff integrity.
- X-rays to rule out bone abnormalities or arthritis.
- Physical examination to evaluate range of motion and strength.
Procedure Description
The procedure typically involves the following steps:
- The patient is placed under general anesthesia.
- Small incisions are made around the shoulder joint.
- An arthroscope is inserted to visualize the inside of the shoulder.
- Damaged tissue is removed, and the torn rotator cuff is repaired using sutures.
- The incisions are closed, and the shoulder is bandaged.
Preparation for the Procedure
Patients should follow these steps to prepare for surgery:
- Avoid eating or drinking after midnight before the surgery.
- Discuss current medications with the surgeon, especially blood thinners.
- Arrange for transportation to and from the surgical facility.
- Wear loose-fitting clothing on the day of the procedure.
Recovery and Aftercare
Post-operative recovery typically includes:
- Resting the shoulder and avoiding heavy lifting for several weeks.
- Physical therapy to regain strength and mobility.
- Pain management with prescribed medications.
- Keeping the surgical site clean and dry to prevent infection.
Possible Complications
While generally safe, this procedure carries some risks, including:
- Infection at the surgical site.
- Persistent pain or stiffness in the shoulder.
- Re-tear of the rotator cuff.
- Nerve or blood vessel injury during surgery.
