This policy includes tests and procedures that have been deemed obsolete by the Centers for Medicare and Medicaid Services, McKesson Corporation ClaimCheck and other authorities.  Obsolete tests and procedures are those that are outdated and are no longer standard of care.

Transrectal ultrasound-guided core needle biopsy has replaced incisional biopsy of the prostate for diagnosis of prostate cancer.  In the core needle biopsy procedure, a needle is inserted into the wall of the rectum into the prostate gland and a core sample is removed for pathological analysis.  Alternatively, the needle may be inserted through the perineum to the prostate gland.  Typically, about a dozen cores of the prostate are taken.

Prostate abscesses may occur as a complication of prostatitis.  Treatment involves appropriate antibiotics and drainage.  Transurethral evacuation or transperineal aspiration have replaced a prostatotomy as the standard method of drainage of a prostatic abscess. 

For many years, contrast or chain urethrocystography was used to evaluate the lower urinary tract.  This procedure has been replaced by ultrasonography for imaging of the urethrovesical anatomy due to the radiation exposure from contrast or chain urethrocystography and due to the less invasive nature of ultrasonography.

Heart catheterization by left ventricular puncture has been made obsolete by catheterization through the femoral artery or through an upper extremity artery using percutaneous access methods.  Right heart catheterization now is commonly performed from the femoral, internal jugular, or subclavian veins.

Cystourethroscopy has replaced cystotomy or cystostomy for cryosurgery or fulguration of bladder lesions.  Although cystourethroscopy can be used to deliver radioactive substances to the bladder (intravesical brachytherapy), current evidence-based guidelines do not recommend brachytherapy as an established treatment for bladder cancer.

Counterimmunoelectrophoresis is a laboratory technique using an electrical field across a diffusion medium that measures binding of an antibody to an antigen. In clinical medicine, it has been replaced by newer, less labor-intensive immunoassay techniques including enzyme-linked immunosorbent assay (ELISA).

The standard method of sinus irrigation in sinusitis involves placement of an instrument into the sinus and flushing the sinus with sterile water.  This procedure is typically performed with local anesthesia (i.e., novocaine).  The Proetz procedure (saline irrigation combined with suctioning) is an older method of sinus irrigation.  With the patient in the supine position and the head hyperextended, the nose and nasopharynx are partially filled with a saline solution to which a topical decongestant may be added.  Suction is then applied to one nostril while the other is occluded in order to remove the irrigating solution along with the secretions.  These steps may be repeated in order to achieve irrigation and drainage of the sinuses.  The effectiveness of this procedure in improving clinical outcomes of sinusitis and its advantages over the current standard method of sinus irrigation are not well documented in the peer-reviewed published medical literature.

Kadish and colleagues (2001) noted that cardiointegram (CIG)/omnicardiogram is a technique intended to detect abnormalities in the standard 12-lead electrocardiogram (ECG) that are beyond the standard, routine interpretation in patients at risk of cardiac ischemia.  This additional technology consists of a microcomputer that receives output from a standard ECG and transforms it to produce a graphical representation of heart electrophysiological signals.  This procedure is mainly used as a substitute for exercise tolerance testing with thallium imaging in patients for whom a resting ECG may be inadequate to identify changes compatible with coronary artery disease.  These findings are based on theoretical assumption that poor exercise tolerance is related to electrophysiological signals; but this test does not consider the impact of other symptoms or blood flow.  The American College of Cardiology and the American Heart Association do not recommend this test.

Gu et al (2005) stated that mechanical fragility of red blood cells (RBCs) is a critical variable for the hemolysis testing of many important clinical devices, such as pumps, valves, and cannulae, and gas exchange devices.  Unfortunately, no standardized test for RBC mechanical fragility is currently well accepted.  Although many test devices have been proposed for the study of mechanical fragility of RBCs, no one has ever shown that their results have any relevance to a blood pump.  Thus, the fundamental objective of this study was to determine if one or more test devices could be validated as calibrators to document the fragility of the test blood used for any particular test blood.  These investigators compared 5 mechanical fragility test systems to each other and to a Biopump, with respect to hemolysis.  All 5 devices seem to measure the same parameter; the hemo-resistometer most closely matched the pump test results, but the stainless steel bead test may be the most practical for routine calibration purposes.

The Canadian Agency for Drugs and Technologies in Health's report on "Re-assessment of health technologies: Obsolescence and waste" (Joshi et al, 2009) noted that the National Library of Medicine listed examples of health care technologies that were found "to be ineffective or harmful after being widely diffused".  Some of these obsolete technolgies include the following (not an all-inclusive list):

  • Colectomy to treat epilepsy
  • Diethylstilbestrol to improve pregnancy outcomes
  • Gastric bubble for morbid obesity
  • Gastric freezing for peptic ulcer disease
  • Mammary artery ligation for coronary artery disease
  • Optic nerve decompression surgery for non-arteritic anterior ischemic optic neuropathy
  • Quinidine for suppressing recurrences of atrial fibrillation
  • Radiation therapy for acne
  • Supplemental oxygen for healthy premature baby.

Conn (1994) stated that the lupus erythematosus (LE) cell test (also known as LE prep, LE phenomenon; CPT No. 85544, LE Cell Prep) is a diagnostic test for systemic lupus erythematosus (SLE) that is based on an in-vitro immunologic reaction between the patient's autoantibodies to nuclear antigens and damaged nuclei in the testing medium.  It is subject to numerous experimental variables and dependent on subjective interpretation.  The author concluded that it should be abandoned in favor of more definitive, quantitative immunologic tests for this condition.

An UpToDate review on "Diagnosis and differential diagnosis of systemic lupus erythematosus in adults" (Wallace, 2015) states that "Previously, most clinicians relied for the diagnosis of lupus upon the classification criteria that were developed by the American Rheumatism Association (ARA, now the ACR).  The criteria were established by cluster analyses, primarily in academic centers and primarily in Caucasian patients.  The patient is classified with SLE using the ACR criteria if four or more of the manifestations are present, either serially or simultaneously, during any interval of observations.  A positive LE cell test, used in older criteria, was replaced by the presence of antiphospholipid antibodies".

Di Benedetto et al (2002) noted that injection of foreign materials, such as paraffin oil, is an old and obsolete procedure.  The authors described previous uses for this procedure that had been used since the 19th century and the treatment of patients affected by such a disease.

Onate Celdran et al (2012) reported a rare case of penile paraffinoma caused by the subcutaneous or intra-urethral injection of foreign substances containing long-chain saturated hydrocarbons.  These were injected in order to increase the penis size which generated a chronic granulomatous inflammatory reaction.  These investigators presented the case of a 32-year old Bulgarian male who presented with a 2-year history of elastic, slightly painful penis swelling after subcutaneous liquid paraffin injection.  The proposed treatment was excision of the affected tissue and penile reconstruction in a 2-stage procedure.  The operative procedure was successful and the patient had good aesthetic and functional results.  Paraffin and other materials injected into the penis can produce many complications.  Foreign body granuloma, skin necrosis, penile deformity, chronic and unhealed ulcer, painful erection, and the inability to achieve a satisfactory sexual relationship are some of the resulting complications.  Intra-lesional or systemic steroids have been used in primary sclerosing lipogranuloma resulting in the disappearance of the granuloma, but in the authors’ opinion the treatment of choice should be radical excision, and, if necessary, secondary reconstruction of the penis.  The authors concluded that injection of foreign substances to enhance penis size is currently an unjustifiable practice.  However, it is still carried out, especially in Eastern Europe and Asia.  In most cases surgical treatment is needed to treat the complications and the best modality seems to be radical excision together with follow-up.

Renal Decapsulation for the Treatment of Anuria

Drager and colleagues (2017) stated that in the early 20th century, Harrison first performed renal decapsulation in anuric children with scarlet fever and observed improvement in renal function post-operatively.  The pathophysiological explanation was seen in intra-parenchymal renal pressure due to edema which was improved by surgical decapsulation.  The technique of decapsulation was simple excision after incision and blunt dissection of the renal parenchyma.  Renal decapsulation then became a procedure commonly used for many indications in inflammatory renal conditions; indications were renal angioneurosis, hydronephrosis, toxic, bacterial and chronic nephritis, renal abscess and even eclampsia.  The authors concluded that with the beginning of the antibiotic era, renal decapsulation became obsolete and has disappeared from the urological spectrum completely.

Radical Parametrectomy after "Cut-Through" Hysterectomy in Low-Risk Early-Stage Cervical Cancer

Pareja and colleagues (2018) identified predictive factors in patients with a diagnosis of early-stage cervical cancer after simple hysterectomy in order to avoid a radical parametrectomy.  A retrospective review was performed of all patients who underwent radical parametrectomy and bilateral pelvic lymphadenectomy at MD Anderson Cancer Center and at the Instituto de Cancerologia Las Americas in Medellin, Colombia from December 1999 to September 2017.  These researchers sought to determine the outcomes in patients diagnosed with low-risk factors (squamous, adenocarcinoma or adeno-squamous lesions less than 2-cm in size, and invading less than 10 mm) undergoing radical parametrectomy and pelvic lymphadenectomy.  A total of 30 patients were included in the study.  The median age was 40.4 years (range of 26 to 60) and median body mass index (BMI) was 26.4kg/m2 (range of 17.7 to 40.0).  A total 22 patients had tumors less than 1 cm and 8 had tumors between 1 and 2 cm.  A total of 6 (33 %) of 18 patients had evidence of lymph-vascular invasion (LVSI).  No radical parametrectomy specimen had residual tumor, involvement of the parametrium, vaginal margin positivity, or lymph node metastasis.  None of the patients received adjuvant therapy.  After a median follow-up of 99 months (range of 6 to 160) only 1 patient recurred.  The authors concluded that radical parametrectomy may be avoided in patients with low-risk early-stage cervical cancer detected after a simple hysterectomy; rates of residual disease (parametrial or vaginal) and the need for adjuvant treatments or recurrences were very low.

Chest Radiography in the Diagnosis of Rib Fractures

Battle and colleagues (2019) stated that it is well-recognized that the detection of rib fractures is unreliable using chest radiograph.  In a systematic review, these investigators examined if the use of lung ultrasound (US) is superior in accuracy to chest radiography, in the diagnosis of rib fractures following blunt chest wall trauma.  The search filter was used for international online electronic databases including Medline, Embase, Cochrane and ScienceDirect, with no imposed time or language limitations.  Grey literature was searched.  Two review authors completed study selection, data extraction and data synthesis/analysis process.  Quality assessment using the Quality Assessment of Diagnostic Accuracy Studies Tool (QUADAS-2) was completed.  A total of 13 studies were included.  Overall, study results demonstrated that the use of lung US in the diagnosis of rib fractures in blunt chest wall trauma patients appeared superior compared with chest radiograph.  All studies were small, single-center and considered to be at risk of bias on quality assessment.  Meta-analysis was not possible due to high levels of heterogeneity, lack of appropriate reference standard and poor study quality.  The author concluded that the findings of this review showed that lung US may be superior to chest radiography, but the low quality of the studies meant that no definitive statement could be made.

Diagnostic Techniques Used in Visceral Osteopathy

Guillaud and colleagues (2018) stated that in 2010, the World Health Organization (WHO) published benchmarks for training in osteopathy in which osteopathic visceral techniques were included.  These investigators evaluated the scientific literature concerning the reliability of diagnosis and the clinical efficacy of techniques used in visceral osteopathy.  Medline, OSTMED.DR, the Cochrane Library, Osteopathic Research Web, Google Scholar, Journal of American Osteopathic Association (JAOA) website, International Journal of Osteopathic Medicine (IJOM) website, and the catalog of Académie d'ostéopathie de France website were searched through December 2017.  Only inter-rater reliability studies including at least 2 raters or the intra-rater reliability studies including at least 2 assessments by the same rater were included.  For efficacy studies, only RCT or cross-over studies on unhealthy subjects (any condition, duration and outcome) were included.  Risk of bias was determined using a modified version of the quality appraisal tool for studies of diagnostic reliability (QAREL) in reliability studies.  For the efficacy studies, the Cochrane risk of bias tool was used to assess their methodological design; 2 authors performed data extraction and analysis.  A total of 8 reliability studies and 6 efficacy studies were included.  The analysis of reliability studies showed that the diagnostic techniques used in visceral osteopathy were unreliable.  Regarding efficacy studies, the least biased study showed no significant difference for the main outcome.  The main risks of bias found in the included studies were due to the absence of blinding of the examiners, an unsuitable statistical method or an absence of primary study outcome.  The authors stated that the findings of this systematic review led them to conclude that well-conducted and sound evidence on the reliability and the efficacy of techniques in visceral osteopathy is absent.

Solitary Computed Tomography Angiography in Diagnosing Vascular Graft Infection

Reinders Folmer and colleagues (2018) stated that vascular graft infection (VGI), a serious complication in vascular surgery, has a high morbidity and mortality rate.  The diagnosis is complicated by non-specific symptoms and challenged by the variable accuracy of different imaging techniques. The researchers determined the diagnostic value of various imaging techniques to diagnose VGI.  They carried out a systematic review according to the PRISMA guidelines.  Data sources included PubMed/Medline, Embase, and Cochrane from January 1997 until October 2017.  Observational cohort studies were included.  A meta-analysis was conducted on several imaging modalities: computed tomography with or without angiography (CT(A)), 18F-fluoro-d-deoxyglucose positron emission tomography with or without low dose or contrast enhanced CT (FDG-PET(/CT)), and white blood cell scintigraphy with or without single photon emission computed tomography combined with low dose CT (WBC (SPECT/CT)).  Of 4,259 papers, 14 articles were included, containing 8 prospective and 6 retrospective articles.  CTA (I2; 7.4 %), FDG-PET (I2; 36.5 %), and FDG-PET/CT (I2; 36.6 %) showed negligible to moderate heterogeneity, while WBC scintigraphy ± SPECT/CT (I2; 78.6 %) showed considerable heterogeneity.  Pooled sensitivity for CTA was 0.67 (95 % confidence interval [CI]: 0.57 to 0.75), in contrast to FDG-PET of 0.94 (9 5% CI: 0.88 to 0.98), FDG-PET/CT of 0.95 (95 % CI: 0.87 to 0.99), WBC scintigraphy of 0.90 (95 % CI: 0.85 to 0.94), and WBC scintigraphy with SPECT/CT of 0.99 (95 % CI: 0.92 to 1.00).  The pooled specificities were for CTA 0.63 (95 % CI: 0.48 to 0.76), FDG-PET 0.70 (95 % CI: 0.59 to 0.79), FDG-PET/CT 0.80 (95 % CI: 0.69 to 0.89), WBC scintigraphy 0.88 (95 %  CI: 0.81 to 1.94), and WBC scintigraphy SPECT/CT 0.82 (95 % CI: 0.57 to 0.96).  Pre- and post-test results showed that WBC SPECT/CT favored FDG-PET/CT, with a positive post-test probability of 96 % versus 83 %.  The authors concluded that the findings of this meta-analysis suggested the diagnostic performance of WBC scintigraphy combined with SPECT/CT was the greatest in diagnosing VGI.  However, it was a time-consuming technique and not always available.  They stated that FDG-PET/CT may be favorable as the initial imaging technique; and the use of solitary CTA in diagnosing VGI appeared to be obsolete.

The Ali Krogius Procedure for the Treatment of Patello-Femoral Instability

Bangert and colleagues (2022) noted that several interventions are established for treating patella-femoral instability (PFI) in adults.  Fewer exist for pediatric patients without damaging the epiphysis.  To-date, the Ali Krogius (AK) procedure is still being employed.  Most studies are not current and reported varying results in small patient population.  In a retrospective, mono-centric study, these researchers examined the long-term results of the AK method.  This trial evaluated 33 knees in 33 patients who received the AK procedure for recurrent patellar dislocation.  The average age was 20.8 years (range of 6 to 40).  The following functional scores were assessed: Kujala Score, Lysholm Score and Tegner Score.  Subgroup analysis was carried out for patients of less than or equal to 16 years of age.  Available pre-operative imaging was evaluated for known risk factors.  After an average follow-up of 7.8 years (range of 59 to 145 months), a total of 8 (24 %) knees suffered a re-dislocation post-operatively; 7 of the 8 dislocations occurred in patients of less than or equal to 16 years of age; 1 knee (3 %) was revised due to persistent pain.  The median score was 86 points for the Kujala score, and 90 for the Lysholm score.  The median in the Tegner score was level 6.  Clinically, the patellar glide was lateralized in 7 knees (21 %) and an apprehension sign was triggered in 8 knees (24 %).  The authors concluded that including the present study, the existing literature indicates a re-dislocation rate between 24 % and 41 % following the AK procedure.  These investigators concluded that even if the protection of the growth plate speaks for the use of the AK procedure in skeletally immature patients, it must be described as obsolete due to the relatively high rate of re-dislocation.  This study retaliated an important message which is consistent with older existing studies in the medical literature.  Other surgical interventions such as medial patella-femoral ligament reconstruction with femoral drilling distal to the growth plate should thus be preferred.


Ramos et al (2022) noted that current evidence suggested that the hysterosalpingo-foam sonography test (HyFoSy) has emerged as a new option to make Fallopian tube assessment easier.  Several published studies have compared the different types of tubal patency test available with the accepted gold standard, laparoscopy and dye, endorsing the advantages of HyFoSy over the other techniques.  However, the authors wondered why professionals nowadays do not indicate HyFoSy as a 1st-choice diagnostic tool, with X-ray hysterosalpingography as still the most recommended procedure in outpatients.  The authors highlighted the latest updates on this topic in order to raise awareness of the benefits of hysterosalpingo-contrast sonography as well as provided some tips for performing HyFoSy to obtain the maximum information in a single consultation.

On the other hand, an UpToDate review on “Hysterosalpingography” (Lee and Kilcoyne, 2023) states that “Hysterosalpingography (HSG) is an outpatient fluoroscopy procedure that evaluates the uterine cavity and fallopian tube patency.  HSG is commonly performed as part of an infertility evaluation … Hysterosalpingography is a fluoroscopic evaluation of the inner contour of the uterus and fallopian tubes.  Information obtained by HSG includes the width/length of the cervix, shape of the uterine cavity, outline of the cornua and lumen for each fallopian tube, contrast spill (or absence) from the tubes, and, in some cases, information about peritoneal adhesions around the tubes”.
