<!DOCTYPE html> <body><h4></h4> <h4>Subject:</h4> <h4>Description</h4><p>This document addresses the medical necessity of an inpatient admission for radiation treatment for cervical and thyroid cancer. Radiation implants, also called brachytherapy, may be placed in interstitial or intracavitary spaces for the treatment of cervical cancer. Thyroid cancer may be treated with radioactive iodine such as I-131. Individuals are discharged from the hospital after the radiation implants are removed and the levels of radioactivity are deemed safe and appropriate for discharge.</p><p><strong>Note:</strong></p><ul> <li>This document does not address the use of I-131, a radioactive substance when used as a diagnostic tool in an I-131 scan.</li> <li>Federal or State regulations will supersede the guideline Length of Stay included under both Clinical Indications section and Goal Length of Stay (GLOS) sections.</li></ul><h4>Clinical Indications</h4><p><strong>Medically Necessary:</strong></p><p>An inpatient admission for radiation treatment for cervical or thyroid cancer is considered <strong>medically necessary</strong> for the period of time the individual’s calculated level of radioactivity is greater than the discharge guidelines set by the U.S. Nuclear Regulatory Commission (USNRC, 2020).

High-dose rate (HDR) brachytherapy, which involves exposing the target area to strong radiation for short periods of time, is done on an outpatient basis. The implant remains only an hour or less and is done weekly repeated three to five times. Low-dose rate (LDR) brachytherapy requires that the radiation source be left in place from approximately 1 to 4 days. LDR brachytherapy is applied using an intracavitary, interstitial or a combination approach (Banerjee, 2014). Interstitial implants containing the radioactive material are placed next to the target area using either an applicator or catheters. The individual may remain hospitalized until the implants are removed and the individual meets discharge criteria.</p><p>Generally, for thyroid cancer, I-131 therapy is done after a total or a partial thyroidectomy. The thyroid absorbs almost all of the body’s iodine. I-131 is used to destroy cancer cells that take up iodine and were not removed by surgery and those that have spread beyond the thyroid (American Cancer Society [ACS], 2019). Therapy is given in either liquid or pill form. Dosing of the therapy can be calculated using an empiric or fixed dosing, quantitative dosimetry, or upper bound limits set by blood dosimetry (National Comprehensive Cancer Network<sup>®</sup> [NCCN<sup>®</sup>], 2023). The most widely used and the simplest method is the empiric or fixed dose. The individual’s dose is determined by the extent of their disease with typical doses within 30-200 mCi (NCCN, 2022). In the past, individuals were routinely hospitalized for I-131 radiation therapy. Hospitalization is no longer routinely required because a change in federal legislation permits the use of much larger doses in ambulatory individuals (NCCN, 2023; U.S. Nuclear Regulatory Commission [USNRC], 2019). Wu and associates (2020) surveyed thyroid cancer survivors to evaluate practice changes regarding hospital release of individuals with differentiated thyroid cancer treated with I-131. Prior to 2009, approximately 66% of thyroid cancer survivors were treated in the outpatient setting. After 2011, the rate of thyroid cancer survivors treated in the outpatient setting has risen to 87%.</p><p>Individuals are encouraged to drink fluids to help the I-131 pass quickly through the body. I-131 is excreted in all body fluids. Therefore, all objects coming into contact with the individual that may be contaminated with sweat, urine, feces, blood or other body fluids are considered radioactive. Within a few days, most of the radiation has been excreted.</p><p>According to the U.S. Nuclear Regulatory Commission regulations (2020), individuals treated with various forms of radioactive implants may be released from the treating facility’s control when contact with that individual will not expose others to a total effective dose equivalent not likely to exceed 5 millisieverts (mSv) (0.5 rem). The facility must also provide the affected individual or caregiver with written instructions to minimize exposure to others to as low as is reasonably achievable (ALARA). A radiation survey is done prior to discharge. There are 3 pathways to determine the dose rate at which individuals can be released. These are based upon the level and type of radionuclide administered during therapy. Local or State regulations may differ from the U.S. Nuclear Regulatory Commission (USNRC, 2020). For safety, the survey requires exposure rate radiation levels be determined in the individual's room and the surrounding area, recorded, and maintained for inspection by the department.</p><h4>References</h4><p><strong>Peer Reviewed Publications:</strong></p><ol> <li class="MsoHeader">Al-Shakhrah IA.

With this method, in accordance with 10 CFR 35.75(a), the licensee must calculate the maximum likely dose to an individual exposed to the patient on a case-by-case basis. If the calculated maximum likely dose to an individual is no greater than 5 mSv (0.5 rem), the licensee may release the patient. Using this method, licensees may be able to release patients with activities greater than those listed in Column 1 of Table 1 by accounting for the effective half-life of the radioactive material and other factors that may be relevant to the particular case. If the dose calculation considered retained activity, an occupancy factor less than 0.25 at 1 meter, the effective half-life, or shielding by tissue, then 10 CFR 35.2075(a) requires the licensee to maintain a record of the basis for authorizing the patient’s release.</p><p><strong>Table 1 Activities and Dose Rates for Authorizing Patient Release<sup>a</sup></strong></p><h4> </h4><h4></h4><p><strong><em>Notes: </em></strong></p><p>The millicurie (mCi) values in Table 1 were calculated using Equation 2 or 3 and the physical half-life. The gigabecquerel (GBq) values were calculated based on the mCi values and the conversion factor from mCi to GBq. The dose rate values were calculated based on the mCi values and the exposure rate constants. In general, the values were rounded to two significant figures. However, values less than 0.37 GBq (10 mCi) or 0.1 mSv (10 millirem (mrem)) per hour were rounded to one significant figure. NUREG-1492 describes the calculations in detail. Agreement State regulations may vary. Agreement State licensees should check their State regulations before using these values.</p><p> </p><hr/><p>Federal and State law, as well as contract language, and Medical Policy take precedence over Clinical UM Guidelines.
