The CPT® Code 82365 refers to a laboratory test that utilizes infrared spectroscopy to analyze the composition of renal calculi, commonly known as kidney stones. This procedure is essential for understanding the specific materials that constitute the stones formed in the kidneys. As the kidneys filter blood and produce urine, various chemicals can precipitate, leading to the formation of crystals. These crystals may consist of minerals, cysteine, or a combination of both. The presence of kidney stones can result in significant complications, including obstruction of urine and blood flow within the kidneys, or they may dislodge and travel down the ureters. This movement can stretch, irritate, and damage the walls of the ureters, causing pain and potential further medical issues. To perform the analysis of the calculi, urine is collected in a clean container and subsequently strained through a fine mesh to capture the stones. Once collected, the calculi are transported to a laboratory for further examination. Typically, a qualitative analysis of the stones is conducted first, which is documented separately. Following this, samples from the surface, core, and cross-section of the stones are taken for detailed analysis using infrared spectrometry, as indicated by CPT® Code 82365. Alternatively, the stones may also be analyzed using roentgenogram (X-ray) diffraction, which is documented under CPT® Code 82370, to create a diffractogram. The results of these analyses are then compared against a comprehensive database of known stone composition materials, allowing for an accurate determination of the specific composition of the calculi.

The procedure associated with CPT® Code 82365 is indicated for the analysis of renal calculi, which are commonly referred to as kidney stones. The following conditions and symptoms may warrant this laboratory test:
The procedure for analyzing renal calculi using infrared spectroscopy involves several key steps, which are detailed below:
After the analysis is completed, the results will be documented and reported to the requesting physician. The findings can provide valuable insights into the type of kidney stones present, which can inform treatment decisions and preventive measures. Patients may be advised on dietary changes or medications based on the composition of their stones to help prevent future occurrences. Additionally, any necessary follow-up appointments or further diagnostic tests may be scheduled based on the results of the analysis.

| 90 | Reference (outside) laboratory: when laboratory procedures are performed by a party other than the treating or reporting physician or other qualified health care professional, the procedure may be identified by adding modifier 90 to the usual procedure number. | GZ | Item or service expected to be denied as not reasonable and necessary | 26 | Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number. | 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | 76 | Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service. | 77 | Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service. | 91 | Repeat clinical diagnostic laboratory test: in the course of treatment of the patient, it may be necessary to repeat the same laboratory test on the same day to obtain subsequent (multiple) test results. under these circumstances, the laboratory test performed can be identified by its usual procedure number and the addition of modifier 91. note: this modifier may not be used when tests are rerun to confirm initial results; due to testing problems with specimens or equipment; or for any other reason when a normal, one-time, reportable result is all that is required. this modifier may not be used when other code(s) describe a series of test results (eg, glucose tolerance tests, evocative/suppression testing). this modifier may only be used for laboratory test(s) performed more than once on the same day on the same patient. | GA | Waiver of liability statement issued as required by payer policy, individual case | GW | Service not related to the hospice patient's terminal condition | PD | Diagnostic or related non diagnostic item or service provided in a wholly owned or operated entity to a patient who is admitted as an inpatient within 3 days | X5 | Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician |
