Section DWD 81.10 - Complex regional pain syndrome of the upper and lower extremities(1) SCOPE. (a) Complex regional pain syndrome of the upper and lower extremities encompasses any condition of the upper or lower extremity characterized by findings in all of the following categories: 1. One or more findings reported by the patient in 3 or more of the following categories: a. Positive sensory abnormalities, which include spontaneous pain, mechanical hyperalgesia, thermal hyperalgesia, and deep somatic hyperalgesia.b. Vascular abnormalities, which include vasodilation, vasoconstriction, skin temperature asymmetries, and skin color changes.c. Swelling or sweating abnormalities.d. Motor and trophic changes, which include motor weakness, tremor, abnormal movements, coordination deficits, nail changes, hair changes, skin atrophy, joint stiffness, and soft tissue changes.2. One or more findings observed by the health care provider in 2 or more of the following categories:a. Positive sensory abnormalities, which include spontaneous pain, mechanical hyperalgesia, thermal hyperalgesia, and deep somatic hyperalgesia.b. Vascular abnormalities, which include vasodilation, vasoconstriction, skin temperature asymmetries, and skin color changes.c. Edema or sweating abnormalities, which include swelling, hyperhidrosis, and hypohidrosis.d. Motor and trophic changes, which include motor weakness, tremor, abnormal movements, coordination deficits, nail changes, hair changes, skin atrophy, joint stiffness, and soft tissue changes.(b) Complex regional pain syndrome of the upper and lower extremities includes the diagnoses of complex regional pain syndrome, reflex sympathetic dystrophy, causalgia, Sudek's atrophy, algoneurodystrophy, shoulder-hand syndrome, including ICD-9-CM codes 337.9, 354.4, and 733.7.(c) Complex regional pain syndrome occurs as a complication of another preceding injury. The treatment guidelines of this section refer to the treatment of the body part affected by the complex regional pain syndrome. The treatment for any condition not affected by complex regional pain syndrome continues to be subject to whatever treatment guidelines otherwise apply. Any treatment under this section for complex regional pain syndrome may be in addition to treatment received for the original condition.(d) Thermography may be used in the diagnosis of complex regional pain syndrome and is considered an adjunct to physical examination.(e) For a patient with continued clinical signs and symptoms of complex regional pain syndrome, further diagnostic testing may be appropriate.(2) INITIAL NONSURGICAL INVOLVEMENT. (a) A health care provider shall use initial nonsurgical management for all patients with complex regional pain syndrome and this shall be the first phase of treatment. Any course or program of initial nonsurgical management is limited to the modalities specified in pars. (b) to (i).(b) The only therapeutic injection modalities necessary for complex regional pain syndrome are sympathetic block, intravenous infusion of steroids or sympatholytics, or epidural block. 1. Unless medically contraindicated, sympathetic blocks or the intravenous infusion of steroids or sympatholytics shall be used if complex regional pain syndrome has continued for 4 weeks and the patient remains disabled as a result of the complex regional pain syndrome. All of the following guidelines apply to therapeutic injection modalities: a. Time for treatment response is within 30 minutes.b. Maximum treatment frequency permits a repeat injection at a site if there was a positive response to the first injection. If subsequent injections demonstrate diminishing control of symptoms or fail to facilitate objective functional gains, then injections shall be discontinued. Only 3 injections to different sites per patient visit.c. Maximum treatment duration may be continued as long as injections control symptoms and facilitate objective functional gains if the period of improvement is progressively longer with each injection.2. Epidural block may only be performed in patients who had an incomplete improvement with sympathetic block or intravenous infusion of steroids or sympatholytics.(c) Only the passive treatment modalities set forth in pars. (d) to (g) are necessary. These passive treatment modalities in a clinical setting or requiring attendance by a health care provider are not necessary beyond 12 weeks from the first modality initiated for treatment of complex regional pain syndrome.(d) For purposes of this paragraph, "thermal treatment" includes all superficial and deep heating and cooling modalities. Superficial thermal modalities include hot packs, hot soaks, hot water bottles, hydrocollators, heating pads, ice packs, cold soaks, infrared, whirlpool, and fluidotherapy. Deep thermal modalities include diathermy, ultrasound, and microwave. All of the following guidelines apply to thermal treatment: 1. Treatment given in a clinical setting: a. Time for treatment response is 2 to 4 treatments.b. Maximum treatment frequency is up to 5 times per week for the first one to 3 weeks, decreasing in frequency until the end of the maximum treatment duration period in subd. 1. c. c. Maximum treatment duration is 12 weeks of treatment in a clinical setting but only if given in conjunction with other therapies specified in this subsection.2. Home use of thermal modalities may be prescribed at any time during the course of treatment. Home use may only involve hot packs, hot soaks, hot water bottles, hydrocollators, heating pads, ice packs, and cold soaks that can be applied by the patient without professional assistance. Home use of thermal modalities may not require any special training or monitoring, other than that usually provided by a health care provider during an office visit.(e) For purposes of this paragraph, "desensitizing procedures" includes stroking or friction massage, stress loading, and contrast baths. All of the following guidelines apply to desensitizing procedures:1. Time for treatment response is 3 to 5 treatments.2. Maximum treatment frequency in a clinical setting is up to 5 times per week for the first one to 2 weeks decreasing in frequency until the end of the maximum treatment duration period in subd. 3.3. Maximum treatment duration in a clinical setting is 12 weeks. Home use of desensitizing procedures may be prescribed at any time during the course of treatment.(f) For purposes of this paragraph, "electrical stimulation" includes galvanic stimulation, transcutaneous electrical nerve stimulation, interferential, and microcurrent techniques. All of the following guidelines apply to electrical stimulation treatment: 1. Treatment given in a clinical setting: a. Time for treatment response is 2 to 4 treatments.b. Maximum treatment frequency is up to 5 times per week for the first one to 3 weeks, decreasing in frequency until the end of the maximum treatment duration period in subd. 1. c. c. Maximum treatment duration is 12 weeks of treatment in a clinical setting, but only if given in conjunction with other therapies.2. Home use of an electrical stimulation device may be prescribed at any time during a course of treatment. Initial use of an electrical stimulation device shall be in a supervised setting in order to ensure proper electrode placement and patient education. All of the following guidelines apply to home use of an electrical stimulation device:a. Time for patient education and training is one to 3 sessions.b. Patient may use the electrical stimulation device unsupervised for one month, at which time effectiveness of the treatment shall be reevaluated by a health care provider before continuing home use of the device.(g) For purposes of this paragraph, "acupuncture treatments" include endorphin-mediated analgesic therapy that includes classic acupuncture and acupressure. All of the following guidelines apply to acupuncture treatments: 1. Time for treatment response is 3 to 5 sessions.2. Maximum treatment frequency is up to 3 times per week for the first one to 3 weeks, decreasing in frequency until the end of the maximum treatment duration period in subd. 3.3. Maximum treatment duration is 12 weeks.(h) Active treatment includes supervised and unsupervised exercise. After the first week of treatment, initial nonsurgical management shall include exercise. Exercise is essential for a return to normal activity and shall include active patient participation in activities designed to increase flexibility, strength, endurance, or muscle relaxation. Exercise shall be specifically aimed at the involved musculature. Exercises shall be evaluated to determine if the desired goals are being attained. Strength, flexibility, or endurance shall be objectively measured. A health care provider may objectively measure the treatment response as often as necessary for optimal care. 1. `Guidelines for supervised exercise.' One goal of a supervised exercise program shall be to teach the patient how to maintain and maximize any gains experienced from exercise. Self-management of the condition shall be promoted. All of the following guidelines apply to supervised exercise:a. Maximum treatment frequency is up to 5 times per week for 3 weeks and shall decrease in frequency until the end of the maximum treatment duration period in subd. 1. b.b. Maximum duration is 12 weeks.2. `Guidelines for unsupervised exercise.' Unsupervised exercise shall be provided in the least intensive setting and may supplement or follow the period of supervised exercise. Maximum duration is unlimited.(i) Oral medications may be necessary in accordance with accepted medical practice.(3) SURGERY. (a) Surgical sympathectomy may only be performed on a patient who had a sustained but incomplete improvement with sympathetic blocks by injection.(b) There shall be appropriate psychological assessment prior to implantation of a spinal cord stimulator or intrathecal drug delivery system to determine whether the patient is a suitable candidate for this type of treatment.(4) CHRONIC MANAGEMENT. If the patient continues with symptoms and objective physical findings after surgery, or the patient refuses surgery, or the patient was not a candidate for surgery, and if the patient's condition prevents the resumption of the regular activities of daily life including regular vocational activities, then the patient may be a candidate for chronic management. Any course or program of chronic management for patients with complex regional pain syndrome shall be provided under the guidelines of s. DWD 81.13.Wis. Admin.
