DWD 81.04 General treatment guidelines; excessive treatment. DWD 81.04(1)(a)(a) All treatment shall be medically necessary treatment. A health care provider shall evaluate the medical necessity of all treatment under
par. (b) on an ongoing basis. This chapter does not require or permit any more frequent examinations than would normally be required for the condition being treated but may require ongoing evaluation of the patient that is medically necessary and consistent with accepted medical practice.
DWD 81.04(1)(b)
(b) The health care provider shall evaluate at each visit whether initial nonsurgical treatment for the low back, cervical, thoracic, and upper extremity conditions specified in
ss. DWD 81.06 to
81.09 is effective according to
subds. 1. to
3. No later than any applicable treatment response time in
ss. DWD 81.06 to
81.09, the health care provider shall evaluate whether the passive, active, injection, or medication treatment modality is resulting in progressive improvement as specified in all of the following:
DWD 81.04(1)(b)1.
1. The patient's subjective complaints of pain or disability are progressively improving, as evidenced by documentation in the medical record of decreased distribution, frequency, or intensity of symptoms.
DWD 81.04(1)(b)2.
2. The objective clinical findings are progressively improving, as evidenced by documentation in the medical record of resolution or objectively measured improvement in physical signs of injury.
DWD 81.04(1)(b)3.
3. The patient's functional status, especially vocational activities, is progressively improving, as evidenced by documentation in the medical record or successive reports of work ability of less restrictive limitations on activity.
DWD 81.04(1)(c)
(c) Except as otherwise provided under
ss. DWD 81.06 (3) (b),
81.07 (3) (b),
81.08 (3) (b), and
81.09 (3) (b), if there is not progressive improvement in at least 2 criteria of
par. (b) 1. to
3., the modality shall be discontinued or significantly modified, or the health care provider shall reconsider the diagnosis. The evaluation of the effectiveness of the treatment modality may be delegated to an allied health professional directly providing the treatment.
DWD 81.04(1)(d)
(d) The health care provider shall use the least intensive setting appropriate and shall assist the patient in becoming independent in the patient's own care to the extent possible so that prolonged or repeated use of health care providers and medical facilities is minimized.
DWD 81.04(2)
(2) Documentation. A health care provider shall maintain an appropriate record of any treatment provided to a patient. An appropriate record is a legible health care service record or report that substantiates the nature and necessity of a health care service being billed and its relationship to the work injury.
DWD 81.04(3)
(3) Nonoperative treatment. A health care provider shall provide a trial of nonoperative treatment before offering or performing surgical treatment unless the treatment for the condition requires immediate surgery, unless an emergency situation exists, or unless the accepted standard of initial treatment for the condition is surgery.
DWD 81.04(4)
(4) Chemical dependency. A health care provider shall maintain diligence to detect incipient or actual chemical dependency to any medication prescribed for treatment of the patient's condition. In cases of incipient or actual dependency, the health care provider shall refer the patient for appropriate evaluation and treatment of the dependency.
DWD 81.04(5)
(5) Departure from guidelines. A health care provider's departure from a guideline that limits the duration or type of treatment in this chapter may be appropriate in any of the following circumstances:
DWD 81.04(5)(b)
(b) Previous treatment did not meet the accepted standard of practice and meet the guidelines in this chapter for the health care provider who ordered the treatment.
DWD 81.04(5)(c)
(c) The treatment is necessary to assist the patient in the initial return to work where the patient's work activities place stress on the part of the body affected by the work injury. The health care provider shall document in the medical record the specific work activities that place stress on the affected body part, the details of the treatment plan, and treatment delivered on each visit, the patient's response to the treatment, and efforts to promote patient independence in the patient's own care to the extent possible so that prolonged or repeated use of health care providers and medical facilities is minimized.
DWD 81.04(5)(d)
(d) The treatment continues to meet 2 of the following 3 criteria, as documented in the medical record:
DWD 81.04(5)(d)1.
1. The patient's subjective complaints of pain are progressively improving as evidenced by documentation in the medical record of decreased distribution, frequency, or intensity of symptoms.
DWD 81.04(5)(d)2.
2. The patient's objective clinical findings are progressively improving, as evidenced by documentation in the medical record of resolution or objectively measured improvement in physical signs of injury.
DWD 81.04(5)(d)3.
3. The patient's functional status, especially vocational activity, is objectively improving, as evidenced by documentation in the medical record or successive reports of work ability of less restrictive limitations on activity.
DWD 81.04(5)(e)

DWD 81.05 Guidelines for medical imaging. DWD 81.05(1)(a)(a)
Documentation. Except for emergency evaluation of significant trauma, a health care provider shall document in the medical record an appropriate history and physical examination, along with a review of any existing medical records and laboratory or imaging studies regarding the patient's condition before ordering any imaging study. All medical imaging shall comply with all of the following:
DWD 81.05(1)(b)
(b)
Effective imaging. A health care provider shall initially order the single most effective imaging study for diagnosing the suspected etiology of a patient's condition. No concurrent or additional imaging studies shall be ordered until the results of the first study are known and reviewed by the treating health care provider. If the first imaging study is negative, no additional imaging is necessary except for repeat and alternative imaging allowed under
pars. (e) and
(f).
DWD 81.05(1)(c)
(c)
Appropriate imaging. Imaging solely to rule out a diagnosis not seriously being considered as the etiology of the patient's condition is not necessary.
DWD 81.05(1)(d)
(d)
Routine imaging. Imaging on a routine basis is not necessary unless the information from the study is necessary to develop a treatment plan.
DWD 81.05(1)(e)
(e)
Repeat imaging. Repeat imaging of the same views of the same body part with the same imaging modality is not necessary except for any of the following:
DWD 81.05(1)(e)2.
2. To monitor a therapy or treatment that is known to result in a change in imaging findings and imaging of these changes are necessary to determine the efficacy of the therapy or treatment; repeat imaging is not appropriate solely to determine the efficacy of physical therapy or chiropractic treatment.
DWD 81.05(1)(e)4.
4. To diagnose a change in the patient's condition marked by new or altered physical findings.
DWD 81.05(1)(e)5.
5. To evaluate a new episode of injury or exacerbation that in itself warrants an imaging study.
DWD 81.05(1)(e)6.
6. When the treating health care provider and a radiologist from a different practice have reviewed a previous imaging study and agree that it is a technically inadequate study.
DWD 81.05(1)(f)1.1. Persistence of a patient's subjective complaint or failure of the condition to respond to treatment are not legitimate indications for repeat imaging. In this instance an alternative imaging study may be necessary if another etiology of the patient's condition is suspected because of the failure of the condition to improve.
DWD 81.05(1)(f)2.
2. Alternative imaging may not follow up negative findings unless there has been a change in the suspected etiology and the first imaging study is not an appropriate evaluation for the suspected etiology.
DWD 81.05(1)(f)3.
3. Alternative imaging may follow up abnormal but inconclusive findings in another imaging study. An inconclusive finding may not provide an adequate basis for accurate diagnosis.
DWD 81.05(2)
(2) Specific imaging procedures for low back pain. DWD 81.05(2)(a)(a) Except for the emergency evaluation of significant trauma, a health care provider shall document in the medical record an appropriate history and physical examination, along with a review of any existing medical records and laboratory or imaging studies regarding the patient's condition, before ordering any imaging study of the low back.
DWD 81.05(2)(b)
(b) A health care provider may order computed tomography scanning for any of the following:
DWD 81.05(2)(b)3.
3. When bony lesion is suspected on the basis of other tests or imaging procedures.
DWD 81.05(2)(c)
(c) Except as specified in
par. (b), a health care provider may not order computed tomography scanning in the first 4 weeks after an injury. Computed tomography scanning is necessary after 4 weeks if the patient continues with symptoms and physical findings after the course of initial nonsurgical care and if the patient's condition prevents the resumption of the regular activities of daily life, including regular vocational activities.
DWD 81.05(2)(d)
(d) A health care provider may order magnetic resonance imaging scanning for any of the following:
DWD 81.05(2)(d)3.
3. When previous spinal surgery has been performed and there is a need to differentiate scar due to previous surgery from disc herniation, tumor, or hemorrhage.
DWD 81.05(2)(e)
(e) Except as specified in
par. (d), a health care provider may not order magnetic resonance imaging scanning in the first 4 weeks after an injury. Magnetic resonance imaging scanning is necessary after 4 weeks if the patient continues with symptoms and physical findings after the course of initial nonsurgical care and if the patient's condition prevents the resumption of the regular activities of daily life, including regular vocational activities.
DWD 81.05(2)(f)
(f) A health care provider may order myelography for any of the following:
DWD 81.05(2)(f)1.
1. Myelography may be substituted for otherwise necessary computed tomography scanning or magnetic resonance imaging scanning in accordance with
pars. (b) and
(d), if those imaging modalities are not locally available.
DWD 81.05(2)(f)2.
2. In addition to computed tomography scanning or magnetic resonance imaging scanning, if there are progressive neurologic deficits or changes and computed tomography scanning or magnetic resonance imaging scanning has been negative.
DWD 81.05(2)(f)3.

DWD 81.05(2)(g)1.
1. The patient's condition is predominantly sciatica, there has been previous spinal surgery, and tumor is suspected.
DWD 81.05(2)(g)2.
2. The patient's condition is predominantly sciatica, there has been previous spinal surgery, and magnetic resonance imaging scanning is equivocal.
DWD 81.05(2)(g)3.
3. When spinal stenosis is suspected and the computed tomography scanning or magnetic resonance imaging scanning is equivocal.
DWD 81.05(2)(g)4.
4. If there are progressive neurologic symptoms or changes and computed tomography scanning or magnetic resonance imaging scanning has been negative.
DWD 81.05(2)(g)5.
5. For preoperative evaluation in cases of surgical intervention, but only if computed tomography scanning or magnetic resonance imaging scanning have failed to provide a definite preoperative diagnosis.
