MRI Pelvis - CAM 714

Description
Pelvis magnetic resonance Imaging (MRI) generates images of the organs and structures within the pelvis without the use of ionizing radiation.

GENERAL INFORMATION

It is an expectation that all patients receive care/services from a licensed clinician. All appropriate supporting documentation, including recent pertinent office visit notes, laboratory data, and results of any special testing must be provided. If applicable: All prior relevant imaging results and the reason that alternative imaging cannot be performed must be included in the documentation submitted.

Where a specific clinical indication is not directly addressed in this guideline, medical necessity determination will be made based on widely accepted standard of care criteria. These criteria are supported by evidence-based or peer-reviewed sources such as medical literature, societal guidelines and state/national recommendations.

Policy  
Note: There is no MRI abdomen/pelvis combo (comparable to a CT abdomen/pelvis) such that if imaging of both the abdomen and pelvis are indicated, two separate exams (and authorization) are required (i.e., MRI abdomen and MRI pelvis).

    • Digital rectal examination (DRE) findings
    • PSA elevation not attributed to benign disease

Known Malignancy
Initial Staging

  • Pelvis MRI is indicated (if not previously done) for the following malignancies:
    • Anal Carcinoma
    • Cervical Cancer
    • Gestational Trophoblastic Neoplasia
    • Ovarian Cancer
    • Pediatric Solid Tumors
    • Prostate Cancer
    • Rectal Cancer
    • Uterine Neoplasms
    • Vulvar Cancer
  • For all other malignancies, Pelvis MRI is indicated to clarify indeterminate findings on CT

Restaging51

  • Pelvis MRI is indicated for restaging during active treatment (every 2 – 3 cycles of chemo or immunotherapy, following radiation and/or after surgery) for the following malignancies:
    • Prostate Cancer:
      • Annually if on active surveillance
      • When recurrence is suspected and PSMA PET is not planned (see CG_070-1 PET for further detail)
    • Rectal Cancer

Surveillance52

  • Pelvis MRI is not typically used during surveillance, however, for the cancers listed above, can be considered on a case to case basis OR when CT is contraindicated and cannot be performed

Pre-operative Evaluation

  • For diagnostic purposes prior to pelvic surgery or procedure

Post-Operative/Procedural Evaluation
When not otherwise addressed in the guideline

  • Follow-up of known or suspected post-operative complication (within 6 months) involving the hips or the pelvis53
  • A follow-up study to help evaluate a patient’s progress after treatment, procedure, intervention, or surgery. Documentation requires a medical reason that clearly indicates why additional imaging is needed.

Genetic Syndromes and Rare Diseases
Surveillance Screening Pelvis MRI for the Following KNOWN Genetic Syndromes

  • FAP (Familial Adenomatous Polyposis, annual screening of abdomen and pelvis with MRI or CT for one or more of the following: personal history of desmoid tumor, family history of desmoid tumor or abdominal symptoms suggestive of desmoid tumor54
  • PGL/PCC (Hereditary Paraganglioma/Pheochromocytoma syndromes or SDHx mutations): every 2 years IF whole body MRI (unlisted MRI CPT 76498) NOT available 55 (see CG_063 Unlisted Studies)
  • Multiple Endocrine Neoplasia type 1 (MEN1): annually56
  • For other syndromes and rare diseases not otherwise addressed in the guideline, coverage is based on a case-by-case basis using societal guidance.

Combination Studies
Abdomen/Pelvis MRI

  • As a dedicated CPT code does not exists for Abdomen and Pelvis MRI (unlike CT), when a disease process is reasonably expected to involve both the abdomen and pelvis AND the guideline criteria have been met, two separate authorizations are required: Abdomen MRI (CPT 74181, 74182, 74183) and Pelvis MRI (CPT 72195, 72196, 72197).

Brain/Chest/Abdomen/Pelvis MRI

  • Multiple Endocrine Neoplasia Syndrome Type 1 (MEN-1)
    • Chest/Abdomen/Pelvis annually
    • Brain/Chest/Abdomen/Pelvis every 3 years

Neck/Abdomen/Pelvis MRI and Chest CT

  • PGL/PCC (Hereditary Paraganglioma/Pheochromocytoma syndromes or SDHx mutations): every 2 years IF whole body MRI (unlisted MRI CPT 76498) not available55 (see Unlisted Studies Evolent_CG_063)57

Pelvis MRI and Pelvis MRA

  • When needed for clarification of vascular invasion from tumor (including suspected renal vein thrombosis)
  • Prior to uterine artery embolization for fibroids

Pelvis MRI and Fetal MRI

  • When medical necessity has been met for Pelvis MRI (such as for suspected placenta accreta or percreta when ultrasound is indeterminate24 AND medical necessity has been met for Fetal MRI (such as suspected fetal abnormality after ultrasound has been performed), two separate authorizations are required: Pelvis MRI (CPT 72195) and Fetal MRI (CPT 74712).

Combination Studies for Malignancy for Initial Staging or Restaging
Unless otherwise specified in this guideline, indication for combination studies for malignancy for initial staging or restaging:

  • Concurrent studies to include CT or MRI of any of the following areas as appropriate depending on the cancer: Abdomen, Brain, Chest, Neck, Pelvis, Cervical Spine, Thoracic Spine or Lumbar Spine.

Further Evaluation of Indeterminate Findings on Prior Imaging
Unless follow up is otherwise specified within the guideline:

  • For initial evaluation of an inconclusive finding on a prior imaging report that requires further clarification
  • One follow-up exam of a prior indeterminate MR/CT finding to ensure no suspicious interval change has occurred. (No further surveillance unless specified as highly suspicious or change was found on last follow-up exam)

Rationale
PI-RADS Assessment Categories for Prostate Cancer

The assignment of a PI-RADS category is based on mpMRI findings only and does not incorporate other factors, including PSA testing, DRE (digital rectal exam), or clinical history.

  • PI-RADS 1  Very low (clinically significant cancer is highly unlikely to be present)
  • PI-RADS 2  Low (clinically significant cancer is unlikely to be present)
  • PI-RADS 3  Intermediate (the presence of clinically significant cancer is equivocal)
  • PI-RADS 4  High (clinically significant cancer is likely to be present)
  • PI-RADS 5  Very high (clinically significant cancer is highly likely to be present)

*Conservative Therapy
Conservative therapy should include a multimodality approach consisting of a combination of active and inactive components. Inactive components, such as rest, ice, heat, modified activities, medical devices, acupuncture and/or stimulators, medications, injections (epidural, facet, bursal, and/or joint, not including trigger point), and diathermy can be utilized. Active modalities may consist of physical therapy, a physician-supervised home exercise program,** and/or chiropractic care.
 

**Home Exercise Program (HEP)
The following elements are required to meet guidelines for completion of conservative therapy:

  • Information provided on exercise prescription/plan AND
  • Follow up with member with documentation provided regarding lack of improvement (failed) after completion of HEP (after suitable 4-week period), or inability to complete HEP due to physical reason- i.e., increased pain, inability to physically perform exercises. (Patient inconvenience or noncompliance without explanation does not constitute “inability to complete” HEP).
  • Dates and duration of failed PT, physician-supervised HEP, or chiropractic treatment should be documented in the original office notes or an addendum to the notes.

MRI and Lumbosacral Plexopathy
Complete lumbar (L1 – L4) or sacral plexopathy (L5 – S3) may present with weakness, sensory loss, and flaccid loss of tendon reflexes. Clinical diagnosis is confirmed by EMG. Acute and chronic plexopathies may be caused by nerve sheath tumors; infectious, autoimmune, hereditary, or idiopathic neuropathies; extrinsic compression; or trauma. There is no CPT® code specifically for imaging of the LS plexus.

Pudendal neuralgia may be considered in chronic pain patients who meet the Nantes criteria: pain in the area innervated by the pudendal nerve, pain more severe with sitting, pain that does not awaken the patient from sleep, pain with no objective sensory impairment, and pain relieved by pudendal block. All five criteria must be met for diagnosis.

Elevated CA-125 and Pelvic Imaging
There is no evidence that isolated levels of CA-125 with no other clinical or radiologic evidence of pathology is sensitive or specific and should not be performed as an isolated test as it can lead to unnecessary studies and anxiety. It is elevated in most cases of epithelial ovarian cancer and is used in monitoring response to treatment as an adjunct to pelvic US. CA-125 has been shown to be increased in many conditions such as fibroids, adenomyosis, pancreatic cancer, endometriosis, tuberculosis, and interstitial lung disease. MRI is not indicated as a first-line test.

Fever of Unknown Origin
Initial work up prior to CT would include a comprehensive history, repeated physical exam, complete blood count with differential, three sets of blood cultures, chest X-ray, complete metabolic panel, urinalysis, ESR, ANA, RA, CMV IgM antibodies, virus detection in blood, heterophile antibody test, tuberculin test, and HIV antibody test. Lastly, with a negative CXR, only when initial workup and abdomen/pelvis CT/MR fail to identify the cause for fever can Chest CT be approved. If CXR suggests a malignancy and/or source of fever, then Chest CT would be approved.

Paraneoplastic Syndromes
Suspected paraneoplastic syndromes with no established cancer diagnosis: laboratory evaluation and imaging the laboratory evaluation for paraneoplastic syndrome is complex. If the appropriate lab test results are suspicious for malignancy, imaging is indicated.

For SIADH (hyponatremia + increased urine osmolality), there is a high association with small cell lung cancer, therefore imaging typically starts with chest CT. If other symptoms suggest a different diagnosis other than small cell lung cancer, different imaging studies may be reasonable.

For hypercalcemia (high serum calcium, low-normal PTH, high PTHrP) it is reasonable to start with bone imaging followed by a more directed evaluation such as mammogram, chest, abdomen and pelvis imaging as appropriate.

For Cushing syndrome (hypokalemia, normal-high midnight serum ACTH NOT suppressed with dexamethasone) abdominal and chest imaging is reasonable. If dexamethasone suppression test DOES suppress ACTH, pituitary MRI is reasonable.

For hypoglycemia, labs drawn during a period of hypoglycemia (glucose < 55, typically a 72-hour fast) (insulin level, C-peptide and IGF-2:IGF-1 ratio) should be done to evaluate for an insulinoma. An elevated insulin level, elevated C-peptide and/or normal IGF-2:IGF-1 ratio warrants CT or MRI abdomen to look for insulinoma. A low insulin, low C-peptide and/or elevated IGF-2:IGF-1 ratio warrants chest and abdominal imaging.

When a paraneoplastic neurologic syndrome is suspected, nuclear and cytoplasmic antibody panels are often ordered to further identify specific tumor types. Results are needed prior to imaging. Because these tests are highly specific, if an antibody highly associated with a specific cancer is positive, then further imaging for that cancer is reasonable. For example, anti-Hu has a high association with SCLC and chest CT would be reasonable.

Anti-MA2 has a high association with testicular cancer and testicular ultrasound would be a reasonable next step.

Weight Loss
Unintentional weight loss is considered clinically significant if the amount of weight lost over 12 months is ≥ 5%. Older age and higher percentage of weight loss correlates with higher likelihood of malignancy. A targeted evaluation is recommended when there are signs or symptoms suggestive of a specific source. For example, when there is clinically significant weight loss with abdominal pain that prompts an evaluation for an abdominal source of the weight loss; CXR and labs such as TSH would not be needed prior to abdominal imaging. Conversely a smoker with a cough and weight loss would not start with abdominal imaging, a chest X-ray (CXR) would be the first test to start with. When there is no suspected diagnosis, initial evaluation includes CXR, age-appropriate cancer screening (such as colonoscopy and mammography) and labs (including CBC, CMP, HbA1C, TSH, stool hemoccult, ESR/CRP, HIV, Hepatitis C). If this initial evaluation fails to identify a cause of weight loss, then the patient is monitored and if progressive weight loss is seen on subsequent visits/weights, then CT Abdomen/Pelvis is reasonable (MRI if there is a contraindication to CT such as contrast allergy or impaired renal function). Lastly, with a negative CXR, only when initial workup and abdomen/pelvis CT/MR fail to identify the cause for weight loss can Chest CT be approved. If CXR suggests a malignancy and/or source of weight loss, then Chest CT would be approved.

Contraindications and Preferred Studies

  • Contraindications and reasons why a CT/CTA cannot be performed may include impaired renal function, significant allergy to IV contrast, pregnancy (depending on trimester).
  • Contraindications and reasons why an MRI/MRA cannot be performed may include impaired renal function, claustrophobia, non-MRI compatible devices (such as non- compatible defibrillator or pacemaker), metallic fragments in a high-risk location, patient exceeds weight limit/dimensions of MRI machine.
