ICD-10 code G90. 5 for Complex regional pain syndrome I (CRPS I) is a medical classification as listed by WHO under the range - Diseases of the nervous system .
Complex regional pain syndrome (CRPS) is a broad term describing excess and prolonged pain and inflammation that follows an injury to an arm or leg. CRPS has acute (recent, short-term) and chronic (lasting greater than six months) forms. CRPS used to be known as reflex sympathetic dystrophy (RSD) and causalgia.
Type 1 complex regional pain syndrome (CRPS 1), formerly known as reflex sympathetic dystrophy (RSD), is a clinical syndrome of variable course and unknown cause characterized by pain, swelling, and vasomotor dysfunction of an extremity. This condition is often the result of trauma or surgery.
Although the key distinguishing feature between type 1 and type 2 CRPS is the presence of nerve injury in the latter, the symptoms in type 2 still exceed the territory of the injured nerve and are far more complex than expected for neuropathic pain, resembling, thus, to the symptoms of CRPS type 1.
In CRPS type I, there are no nerve injuries or lesions identified. CRPS type I is also known as “reflex sympathetic dystrophy,” and it comprises about 90 percent of all cases of CRPS. CRPS type II (causalgia), on the other hand, is diagnosed when there is evidence of nerve damage.
The three clinical stages of type 1 complex regional pain syndrome (CRPS 1) are acute, subacute, and chronic.
CRPS used to be known as reflex sympathetic dystrophy (RSD) and causalgia. People with CRPS have changing combinations of spontaneous pain or excess pain that is much greater than normal following something as mild as a touch.
CRPS (formerly known as RSD) is classed as the most painful chronic pain condition that is known. It reaches approx 42 out of 50 on the McGill Pain Scale, higher than non-terminal cancer, higher than amputation of a finger without anaesthesia…
Pain is the clinical feature that is considered the hallmark of CRPS and is the problem that prompts the patient to seek treatment. The pain may cause mobility problems disproportionate to the injury itself. All tactile stimulation to the skin is painful (hyperes thesia).
CRPS can progress beyond the original affected body part. It can come to affect other limbs or indeed the whole body. Central sensitization likely plays a role in this progression. Central sensitization is a highly reactive state of the nervous system, which amplifies pain.
During this stage patients usually have a burning type pain, swelling, skin redness, increased sweating, and decreased range of motion. After 3 months, the patient enters the subacute stage. During this stage patients have continued severe pain, swelling, skin dryness, and paleness or bluish coloration of the skin.
Relative to CRPS, FM is associated with less intense and generally widespread pain, and tenderness in the musculoskeletal system. In addition, unlike FM, CRPS is usually characterized by changes in skin color and temperature at the site of the original tissue injury, suggesting local sympathetic hyperactivity.
Physical therapy is the cornerstone and first-line treatment for CRPS. Physical therapy is one of the few interventions that have been shown in controlled studies to be effective.
Many cases of CRPS occur after a forceful trauma to an arm or a leg. This can include a crushing injury or a fracture. Other major and minor traumas — such as surgery, heart attacks, infections and even sprained ankles — also can lead to CRPS . It's not well understood why these injuries can trigger CRPS .
How is complex regional pain syndrome treated? This syndrome has no cure. But sometimes the symptoms get better or stop on their own. Some evidence suggests early treatment, particularly with physical therapy, can help limit the disease.
The Social Security Administration recognizes Complex Regional Pain Syndrome as a potential cause of disability, but the condition does not have its own listing in the Blue Book. The SSA does not differentiate between Type I and Type II.

The 2022 edition of ICD-10-CM G90.529 became effective on October 1, 2021.
The ICD code G90 is used to code Dysautonomia. Dysautonomia (or autonomic dysfunction, autonomic neuropathy) is an umbrella term for various conditions in which the autonomic nervous system (ANS) does not work correctly.

Type-1 Excludes mean the conditions excluded are mutually exclusive and should never be coded together. Excludes 1 means "do not code here."
As there is no gold standard test for CRPS, several clinical diagnostic criteria have been introduced and applied in various studies. However, to date, no formal or standardized diagnostic criteria for CRPS have been widely accepted.
Diagnosis of Complex regional pain syndrome (CRPS) is made primarily on a clinical basis, and no specific test is known to confirm or exclude CRPS diagnosis. That is, there aren't specific diagnostic tools and instrumental tests are made only for identifying an etiology at the basis of the CRPS. Num …
In a case-report, Fritz and colleagues (2019) presented an application of percutaneous peripheral nerve stimulation (PNS) to the left ulnar nerve to treat a patient with CRPS1 following a crush injury to the left 5th digit. Conventional treatment had failed to ameliorate the patient's condition. After a successful 7-day trial with an ulnar peripheral nerve catheter, which followed an unsuccessful capsulectomy of the metacarpophalangeal and proximal interphalangeal joints of the left 5th digit with tenolysis of the flexor tendons, the patient underwent an uneventful implantation of a percutaneous peripheral nerve stimulator parallel with the trajectory of the left ulnar nerve just distal to the ulnar tunnel. Two weeks after implantation of the percutaneous peripheral nerve stimulator, the patient reported a reduction in the pain, with the intensity score coming down from 7 out of 10 to 0 to 1 out of 10 on the NRS. The patient was able to initiate pain-free active motion of her left 5th digit. At the 3-month follow-up consultation, the patient reported maintenance of the reduction of pain in her left upper extremity with the implanted percutaneous peripheral nerve stimulator, as well as improved performance in her daily activities. The authors concluded that despite the success achieved in this particular case, further clinical series involving larger numbers of patients are needed to examine the definitive role of percutaneous PNS for the treatment of neuropathic pain of the upper and lower extremities, which has been previously unresponsive to medical and/or surgical treatment.
CRPS-II (formerly "causalgia") describes patients with identified nerve injuries. CRPS-I (formerly "reflex sympathetic dystrophy") describes most patients who lack evidence of specific nerve injuries. Diagnosis is clinical and the pathophysiology involves combinations of small-fiber axonopathy, microvasculopathy, inflammation, and brain plasticity/sensitization. Females have much higher risk and workplace accidents are a well-recognized cause. Inflammation and dysimmunity, perhaps facilitated by injury to the blood-nerve barrier, may contribute. Most patients, particularly the young, recover gradually, but treatment can speed healing. Evidence of effectiveness is strongest for rehabilitation therapies (e.g., graded-motor imagery), neuropathic pain medications, and electric stimulation of the spinal cord, injured nerve, or motor cortex. Investigational treatments include ketamine, botulinum toxin, immunoglobulins, and transcranial neuromodulation. Non-recovering patients should be re-evaluated for neuro-surgically treatable causal lesions (nerve entrapment, impingement, infections, or tumors) and treatable potentiating medical conditions, including polyneuropathy and circulatory insufficiency.
Xu and colleagues (2016) noted that CRPS remains a challenging clinical pain condition. Multi-disciplinary approaches have been advocated for managing CRPS. Compared with spinal cord stimulation and intrathecal targeted therapy, IV treatments are less invasive and less costly. These investigators reviewed the literature on IV therapies and determine the level of evidence to guide the management of CRPS. They searched PubMed, Embase, Scopus, and the Cochrane databases for articles published on IV therapies of CRPS up through February 2015. The search yielded 299 articles, of which 101 were deemed relevant by reading the titles and 63 by reading abstracts. All these 63 articles were retrieved for analysis and discussion. These researchers evaluated the relevant studies and provided recommendations according to the level of evidence. The authors concluded that there is evidence to support the use of IV bisphosphonates, immunoglobulin, ketamine, or lidocaine as valuable interventions in selected patients with CRPS. However, they stated that high-quality studies are needed to further evaluate the safety, effectiveness, and cost-effectiveness of IV therapies for CRPS.
In an evidence-based review on the use of ketamine in the management of chronic pain, Hocking and Cousins (2003) concluded that the evidence for efficacy of ketamine for treatment of chronic pain is moderate to weak and that further controlled studies are needed. Additionally, Kingery (1997) noted that intravenous ketamine is not a realistic option for treatment of chronic neuropathic pain due to intolerable side-effects associated with long-term infusion.
Aetna considers continuous epidural analgesia medically necessary for the treatment of members with intractable complex regional pain syndrome (CRPS), also known as reflex sympathetic dystrophy (RSD), when all of the following selection criteria are met:
On the other hand, there is a lack of scientific evidence on the effectiveness of intrapleural analgesia for treatment of CRPS with chronic pain involving the thoracic dermatomes.
Mendez-Rebolledo et al (2017) stated that graded motor imagery (GMI) and mirror therapy (MT) is thought to improve pain in patients with CRPS types 1 and 2. However, the evidence is limited and analysis are not independent between types of CRPS. These investigators analyzed the effects of GMI and MT on pain in independent groups of patients with CRPS types 1 and 2. Searches for literature published between 1990 and 2016 were conducted in databases; RCTs that compared GMI or MT with other treatments for CRPS types 1 and 2 were included. A total of 6 articles met the inclusion criteria and were classified from moderate to high quality. The total sample was composed of 171 participants with CRPS type 1; 3 studies presented GMI with 3 components and 3 studies only used the MT. The studies were heterogeneous in terms of sample size and the disorders that triggered CRPS type 1. There were no trials that included participants with CRPS type 2. The authors concluded that GMI and MT can improve pain in patients with CRPS type 1; however, there is insufficient evidence to recommend these therapies over other treatments given the small size and heterogeneity of the studied population.
