The CPT® Code 84252 refers to a laboratory test that measures the levels of riboflavin, also known as Vitamin B2, in the blood. Riboflavin is an essential micronutrient that plays a critical role in various bodily functions, including growth and the production of red blood cells (RBCs). It is vital for the metabolism of macronutrients such as fats, proteins, and carbohydrates, as well as ketone bodies, which are produced during fat metabolism. Adequate daily intake of riboflavin is necessary to maintain optimal health, and deficiencies in this vitamin can lead to health issues, including anemia. The test involves obtaining a blood sample through a procedure known as venipuncture, which is reported separately. The plasma obtained from the blood sample is then analyzed using a technique called quantitative high-performance liquid chromatography (HPLC), which allows for precise measurement of riboflavin levels in the plasma. This test is important for diagnosing riboflavin deficiency and monitoring the nutritional status of patients.

The riboflavin (Vitamin B2) blood test, coded as CPT® 84252, is indicated for the assessment of riboflavin levels in patients who may be experiencing symptoms related to deficiency or for monitoring nutritional status. The following conditions may warrant this test:
The procedure for obtaining a riboflavin level involves several key steps that ensure accurate measurement of the vitamin in the blood. The following procedural steps are outlined:
After the blood sample has been collected, the patient may experience minor discomfort or bruising at the venipuncture site, which typically resolves quickly. There are no specific post-procedure care instructions required for this test, but patients should be advised to report any unusual symptoms, such as excessive bleeding or signs of infection at the puncture site. The results of the riboflavin level test will be communicated to the healthcare provider, who will interpret the findings in the context of the patient's overall health and nutritional status.

| 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. | GA | Waiver of liability statement issued as required by payer policy, individual case | 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. | 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. | GW | Service not related to the hospice patient's terminal condition | GY | Item or service statutorily excluded, does not meet the definition of any medicare benefit or, for non-medicare insurers, is not a contract benefit | GZ | Item or service expected to be denied as not reasonable and necessary | Q4 | Service for ordering/referring physician qualifies as a service exemption | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
