DWD 81.07(1)(j)2.2. These blocks and injections are invasive and when done as diagnostic procedures are not necessary unless noninvasive procedures have failed to establish the diagnosis. DWD 81.07(1)(j)3.3. Selection of patients, choice of procedure, and localization of the level of injection shall be determined by documented clinical findings indicating possible pathologic conditions and the source of pain symptoms. DWD 81.07(1)(j)4.4. These blocks and injections may also be used as therapeutic modalities and are subject to the guidelines in sub. (5) DWD 81.07(1)(k)(k) Functional capacity assessment or evaluation is a comprehensive and objective assessment of patient’s ability to perform work tasks. The components of a functional capacity assessment or evaluation include neuromusculoskeletal screening, tests of manual material handling, assessment of functional mobility, and measurement of postural tolerance. A functional capacity assessment or evaluation is an individualized testing process and the component tests and measurements are determined by the patient’s condition and the requested information. Functional capacity assessments and evaluations are performed to determine a patient’s physical capacities in general or to determine and report work tolerance for a specific job, task, or work activity. DWD 81.07(1)(k)1.1. Functional capacity assessment or evaluation is not necessary during the period of initial nonoperative care. DWD 81.07(1)(k)2.2. Functional capacity assessment or evaluation is necessary in any of the following circumstances: DWD 81.07(1)(k)2.a.a. To identify the patient’s permanent activity restrictions and capabilities. DWD 81.07(1)(L)(L) Consultations with other health care providers may be initiated at any time by a treating health care provider consistent with accepted medical practice. DWD 81.07(2)(a)(a) All medical care for neck pain appropriately assigned to a clinical category in sub. (1) (b) is determined by the diagnosis and clinical category that the patient has been assigned. General guidelines for treatment modalities are set forth in subs. (3) to (10). Specific treatment guidelines for each clinical category are set forth in subs. (11) to (14) as follows: DWD 81.07(2)(b)(b) A health care provider shall at each visit reassess the appropriateness of the clinical category assigned and reassign the patient if warranted by new clinical information including symptoms, signs, results of diagnostic testing and opinions, and information obtained from consultations with other health care providers. When the clinical category is changed the treatment plan shall be appropriately modified to reflect the new clinical category. A change of clinical category shall not in itself allow a health care provider to continue a therapy or treatment modality past the maximum duration specified in subs. (3) to (10) or to repeat a therapy or treatment previously provided for the same injury. DWD 81.07(2)(c)(c) In general, a course of treatment is divided into the following 3 phases: DWD 81.07(2)(c)1.1. First, all patients with neck problems, except patients with radicular pain with progressive neurological deficit or myelopathy under sub. (1) (b) 3. and 4., shall be given initial nonsurgical care that may include both active and passive treatment modalities, injections, durable medical equipment, and medications. These modalities and guidelines are described in subs. (3), (4), (5), (8), and (10). The period of initial nonsurgical management begins with the first passive, active, injection, durable medical equipment, or medication modality initiated. Initial nonsurgical treatment shall result in progressive improvement as specified in sub. (9). DWD 81.07(2)(c)2.2. Second, for patients with persistent symptoms, initial nonoperative care is followed by a period of surgical evaluation. This evaluation shall be completed in a timely manner. Surgery, if necessary, shall be performed as expeditiously as possible consistent with sound medical practice and subs. (6), (11) to (14), and s. DWD 81.12 (1). A treating health care provider may do the evaluation or may refer the patient to another health care provider. DWD 81.07(2)(c)2.a.a. Patients with radicular pain with progressive neurological deficit or myelopathy may require immediate surgical therapy. DWD 81.07(2)(c)2.b.b. Any patient who has had surgery may require postoperative therapy with active and passive treatment modalities. This therapy may be in addition to any received during the period of initial nonsurgical management. DWD 81.07(2)(c)2.d.d. A decision against surgery at any particular time does not preclude a decision for surgery made at a later date. DWD 81.07(2)(c)3.3. Third, for those patients who are not candidates for or refuse surgical therapy, or who do not have complete resolution of their symptoms with surgery, a period of chronic management may be necessary. Chronic management modalities are described in s. DWD 81.13 and may include durable medical equipment as described in sub. (8). DWD 81.07(2)(d)(d) A treating health care provider may refer the patient for a consultation at any time during the course of treatment consistent with accepted medical practice. DWD 81.07(3)(a)(a) General. Except as set forth in par. (b) or s. DWD 81.04 (5), a health care provider may not direct the use of passive treatment modalities in a clinical setting as set forth in pars. (c) to (i) beyond 12 calendar weeks after any of the passive modalities in pars. (c) to (i) are initiated. There are no limitations on the use of passive treatment modalities by the patient at home. DWD 81.07(3)(b)(b) Additional passive treatment modalities. A health care provider may direct an additional 12 visits for the use of passive treatment modalities over an additional 12 months to be provided if all of the following apply: DWD 81.07(3)(b)1.1. The patient is released to work or is permanently totally disabled and the additional passive treatment shall result in progressive improvement in, or maintenance of, functional status achieved during the initial 12 weeks of passive care.
