Reflex Sympathetic Dystrophy ICD-10-CM Codes

What ICD-10 Codes are Used for Reflex Sympathetic Dystrophy 

G90.50

As one of the Reflex Sympathetic Dystrophy ICD Codes, this code is applied when diagnosing reflex sympathetic dystrophy is definite, but the specific location of the pain is not identified. Patients might undergo intense pain, alterations in skin temperature, perspiration, blood circulation changes, muscular weakness, or movement irregularities within the affected region.

G90.51

This code is utilized when the pain is situated in the upper limb, like the arm or hand. The patient may undergo the same symptoms noted in G90.50, yet the discomfort is restricted to the upper limb.

G90.52

This reflex sympathetic dystrophy ICD-10 code is employed when the pain occurs in the lower limb, such as the leg or foot. The patient might encounter identical symptoms as listed under G90.50, but the pain is localized to the lower limb.

G90.59

This code is employed when the pain emerges in a location other than the upper or lower limbs, such as the face or chest. The patient might undergo the same symptoms outlined for G90.50, however, the pain is restricted to the designated site.

G90.5A

This reflex sympathetic dystrophy ICD 10 code is used when the patient displays signs of autonomic dysfunction alongside the pain. Symptoms may encompass variations in skin temperature, perspiration, blood circulation, pupil size, heart rate, or blood pressure.

G90.5B

This code is chosen when the patient experiences excessive sweating in the affected region. Sweating might be localized to the impacted area or extend more broadly.

G90.5C

This ICD 10 code for reflex sympathetic dystrophy is utilized when the patient undergoes alterations in blood flow to the afflicted area. These changes can lead to redness, coldness, or swelling in the impacted region.

G90.5D

This ICD 10 reflex sympathetic dystrophy code is used when the patient encounters muscular weakness or tremors in the affected area. The intensity of weakness or tremors can vary from mild to severe.

Which Reflex Sympathetic Dystrophy ICD codes are Billable: 

Yes, the codes (G90.50, G90.51, G90.52, G90.59, G90.5A, G90.5B, G90.5C, G90.5D) are billable for cases involving the diagnosis and treatment of complex regional pain syndrome (CRPS) type I and its varied symptoms. They allow accurate documentation of specific CRPS manifestations, aiding reimbursement and tailored patient care.

Clinical Information

• Reflex Sympathetic Dystrophy (RSD) is a chronic pain disorder affecting one or more limbs.
• Severe pain, skin color changes, sweating irregularities, temperature sensitivity, and movement disorders characterize it.
• The cause of RSD is uncertain, possibly stemming from nerve or blood vessel damage in the affected limb.
• RSD is often triggered by injuries, surgeries, or traumatic events causing limb damage.
• While no cure exists, treatments such as physical therapy, medications, and psychological therapy can manage pain and symptoms.
• With proper care, most individuals can learn to manage RSD symptoms and lead a relatively normal life.
• RSD is more common in women than men.
• The average age of onset is around 40, but it can develop at any age.
• Typically, RSD affects the arms and legs, although it can impact any limb.
• Symptoms can vary and change over time.
• RSD pain is often described as burning, aching, or throbbing.
• The affected skin might be red, cold, or sweaty.
• Swelling and stiffness can occur in the affected limb.
• Weakness or tremors may be present.
• Diagnosis can be challenging due to symptom overlap with other conditions.
• Physicians use physical exams and tests like X-rays or MRIs to rule out alternative causes.

Synonyms Include

• Complex regional pain syndrome (CRPS)
• Causalgia
• Algoneurodystrophy
• Sudeck's atrophy
• Shoulder-hand syndrome
• Distal extremity sympathetic dystrophy
• Reflex neurovascular dystrophy
