During the period of initial nonsurgical management, computerized range of motion or strength testing may be performed but shall be done in conjunction with an office visit with a health care provider's evaluation or treatment, or physical or occupational therapy evaluation or treatment.
DWD 81.06(1)(i)
(i) A health care provider may order personality or psychosocial evaluations for evaluating patients who continue to have problems despite appropriate care. A treating health care provider may perform this evaluation or may refer the patient for consultation with another health care provider in order to obtain a psychological evaluation. These evaluations may be used to assess the patient for a number of psychological conditions that may interfere with recovery from the injury. Since more than one of these psychological conditions may be present in a given case, the health care provider performing the evaluation shall consider all of the following:
DWD 81.06(1)(i)2.
2. Does the patient exhibit an emotional reaction to the injury, such as depression, fear, or anger, that is interfering with recovery?
DWD 81.06(1)(i)3.
3. Are there other personality factors or disorders that are interfering with recovery?
DWD 81.06(1)(i)5.
5. Are there any interpersonal conflicts interfering with recovery?
DWD 81.06(1)(i)6.
6. Does the patient have a chronic pain syndrome or psychogenic pain?
DWD 81.06(1)(i)7.
7. In cases in which surgery is a possible treatment, are psychological factors likely to interfere with the potential benefit of the surgery?
DWD 81.06(1)(j)
(j) All of the following are guidelines for diagnostic analgesic blocks or injection studies and include facet joint injection, facet nerve injection, epidural differential spinal block, nerve block, and nerve root block:
DWD 81.06(1)(j)1.
1. These procedures are used to localize the source of pain before surgery and to diagnose conditions that fail to respond to initial nonsurgical management.
DWD 81.06(1)(j)2.
2. These injections are invasive and are not necessary when done as diagnostic procedures only, unless noninvasive procedures have failed to establish the diagnosis.
DWD 81.06(1)(j)3.
3. Selection of patients, choice of procedure, and localization of the level of injection may be determined by documented clinical findings indicating possible pathologic conditions and the source of pain symptoms.
DWD 81.06(1)(j)4.
4. These blocks and injections may also be used as therapeutic modalities and are subject to the guidelines of
sub. (5).
DWD 81.06(1)(k)
(k) Functional capacity assessment or evaluation is a comprehensive and objective assessment of a 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 and report a patient's physical capacities in general or to determine work tolerance for a specific job, task, or work activity.
DWD 81.06(1)(k)1.
1. A functional capacity assessment or evaluation is not necessary during the period of initial nonsurgical management.
DWD 81.06(1)(k)2.
2. A functional capacity assessment or evaluation is necessary in any of the following circumstances:
DWD 81.06(1)(k)3.
3. A functional capacity evaluation may not establish baseline performance before treatment or for subsequent assessments to evaluate change during or after treatment.
DWD 81.06(1)(k)4.
4. A health care provider may direct only one completed functional capacity evaluation per injury.
DWD 81.06(1)(L)
(L) Consultations with other health care providers may be initiated at any time by the treating health care provider consistent with accepted medical practice.
DWD 81.06(2)
(2) General treatment guidelines for low back pain. DWD 81.06(2)(a)(a) All medical care for low back 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),
(12), and
(13), as follows:
DWD 81.06(2)(a)3.
3. Subsection (13) governs cauda equina syndrome and radicular pain with progressive neurologic deficits.
DWD 81.06(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. If the clinical category is changed, the treatment plan shall be appropriately modified to reflect the new clinical category. A change of clinical category may 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 81.06(2)(c)
(c) In general, a course of treatment for low back problems is divided into the following 3 phases:
DWD 81.06(2)(c)1.
1. First, all patients with low back problems, except patients with progressive neurologic deficit or cauda equina syndrome under
sub. (1) (b) 3. or
4., shall be given initial nonsurgical management which may include active treatment modalities, 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 treatment begins with the first active, passive, medication, durable medical equipment, or injection modality initiated. Initial nonsurgical treatment shall result in progressive improvement as specified in
sub. (9).
DWD 81.06(2)(c)2.
2. Second, for patients with persistent symptoms, initial nonsurgical management 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),
(12),
(13), and
s. DWD 81.12. A treating health care provider may do the evaluation or may refer the patient to another health care provider.
DWD 81.06(2)(c)2.a.
a. Patients with radicular pain with progressive neurological deficit or cauda equina syndrome may require immediate surgical therapy.
