Causalgia of upper limb (Complex regional pain syndrome II of upper limb).
Medical necessity for treatment is established by the presence of persistent pain and functional limitations related to the causalgia. The documentation should support the severity of symptoms and the impact on the patient's ability to perform daily activities.
Diagnosis of causalgia of the upper limb is typically made based on a patient's medical history, physical examination, and reported symptoms.While there are no specific tests to diagnose causalgia, additional investigations such as thermography, sweat testing, MRI, or bone scans might be used to rule out other conditions.
In simple words: Causalgia of the upper limb is a painful condition affecting the arm or hand after a nerve injury. It causes intense, burning pain and other symptoms like skin changes and swelling.
Causalgia of the upper limb, also known as complex regional pain syndrome II (CRPS II), is a chronic pain condition that affects the arm or hand following an injury to the central or peripheral nervous system.Symptoms can include burning or throbbing pain, sensitivity to touch or cold, swelling, changes in skin color, temperature, and texture, sweating, muscle spasms, tremors, weakness, and changes in nail and hair growth.
Example 1: A patient experiences persistent burning pain in their hand several weeks after a wrist fracture., Following a minor cut on their forearm, a patient develops severe pain, swelling, and skin discoloration in the affected area, consistent with CRPS II., A patient undergoing physical therapy for a shoulder injury develops symptoms of causalgia in their arm.
Documentation should include detailed descriptions of the pain characteristics, associated symptoms, and any precipitating events or injuries.Relevant physical exam findings like skin changes, swelling, and range of motion limitations should also be documented.
