Use CPT code 81003 confidently! Urinalysis is a common diagnostic tool and a routine procedure for pathologists. But coding it is a whole different ball game! It is not as simple as dipping the stick into freshly collected urine and sticking it in a reader.&nbsp;<\/p>\n\n\n\n<p>You have to choose between different codes depending on how you analyzed the urine sample. Did you use a dipstick or a reagent tablet? Did you take manual readings or use a machine for interpretation? Performed the test with or without microscopy? Each of these options has a different code. Today, we will be discussing one such code, CPT code 81003.&nbsp;<\/p>\n\n\n\t\t\t\t<div class=\"wp-block-uagb-table-of-contents uagb-toc__align-left uagb-toc__columns-1 uagb-toc__collapse uagb-block-495131bc      \"\n\t\t\t\t\tdata-scroll= \"1\"\n\t\t\t\t\tdata-offset= \"30\"\n\t\t\t\t\tstyle=\"\"\n\t\t\t\t>\n\t\t\t\t<div class=\"uagb-toc__wrap\">\n\t\t\t\t\t\t<div class=\"uagb-toc__title\">\n\t\t\t\t\t\t\tTable Of Contents\t\t\t\t\t\t\t\t\t\t\t\t\t<svg xmlns=\"https:\/\/www.w3.org\/2000\/svg\" viewBox= \"0 0 384 512\"><path d=\"M192 384c-8.188 0-16.38-3.125-22.62-9.375l-160-160c-12.5-12.5-12.5-32.75 0-45.25s32.75-12.5 45.25 0L192 306.8l137.4-137.4c12.5-12.5 32.75-12.5 45.25 0s12.5 32.75 0 45.25l-160 160C208.4 380.9 200.2 384 192 384z\"><\/path><\/svg>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"uagb-toc__list-wrap \">\n\t\t\t\t\t\t<ol class=\"uagb-toc__list\"><li class=\"uagb-toc__list\"><a href=\"#cpt-code-81003-description\" class=\"uagb-toc-link__trigger\">CPT Code 81003 &#8211; Description<\/a><li class=\"uagb-toc__list\"><a href=\"#scenarios-where-cpt-code-81003-is-applicable\" class=\"uagb-toc-link__trigger\">Scenarios Where CPT Code 81003 is Applicable<\/a><ul class=\"uagb-toc__list\"><li class=\"uagb-toc__list\"><a href=\"#automated-urinalysis-to-monitor-a-diabetic-patient\" class=\"uagb-toc-link__trigger\">Automated Urinalysis to Monitor a Diabetic Patient\u00a0<\/a><li class=\"uagb-toc__list\"><li class=\"uagb-toc__list\"><a href=\"#automated-urinalysis-to-evaluate-new-diabetic-symptoms\" class=\"uagb-toc-link__trigger\">Automated Urinalysis to Evaluate New Diabetic Symptoms<\/a><li class=\"uagb-toc__list\"><li class=\"uagb-toc__list\"><a href=\"#automated-urinalysis-to-diagnose-uti\" class=\"uagb-toc-link__trigger\">Automated Urinalysis to Diagnose UTI<\/a><\/li><\/ul><\/li><li class=\"uagb-toc__list\"><a href=\"#applicable-modifiers-for-cpt-code-81003\" class=\"uagb-toc-link__trigger\">Applicable Modifiers for CPT Code 81003<\/a><ul class=\"uagb-toc__list\"><li class=\"uagb-toc__list\"><a href=\"#modifier-qw\" class=\"uagb-toc-link__trigger\">Modifier QW<\/a><li class=\"uagb-toc__list\"><li class=\"uagb-toc__list\"><a href=\"#modifier-59\" class=\"uagb-toc-link__trigger\">Modifier 59<\/a><li class=\"uagb-toc__list\"><li class=\"uagb-toc__list\"><a href=\"#modifier-91\" class=\"uagb-toc-link__trigger\">Modifier 91<\/a><\/li><\/ul><\/li><\/ul><\/li><li class=\"uagb-toc__list\"><a href=\"#cpt-code-81003-billing-reimbursement-guidelines\" class=\"uagb-toc-link__trigger\">CPT Code 81003 &#8211; Billing &amp; Reimbursement Guidelines<\/a><ul class=\"uagb-toc__list\"><li class=\"uagb-toc__list\"><a href=\"#use-81003-for-an-automated-urinalysis-without-microscopy\" class=\"uagb-toc-link__trigger\">Use 81003 for an Automated Urinalysis without Microscopy<\/a><li class=\"uagb-toc__list\"><li class=\"uagb-toc__list\"><a href=\"#justify-the-medical-necessity-of-automated-urinalysis-with-documentation\" class=\"uagb-toc-link__trigger\">Justify the Medical Necessity of Automated Urinalysis with Documentation<\/a><li class=\"uagb-toc__list\"><li class=\"uagb-toc__list\"><a href=\"#use-modifier-qw-if-applicable\" class=\"uagb-toc-link__trigger\">Use Modifier QW (if Applicable)<\/a><li class=\"uagb-toc__list\"><li class=\"uagb-toc__list\"><a href=\"#understand-payer-requirements\" class=\"uagb-toc-link__trigger\">Understand Payer Requirements<\/a><\/li><\/ul><\/li><\/ul><\/li><\/ul><\/li><li class=\"uagb-toc__list\"><a href=\"#summary\" class=\"uagb-toc-link__trigger\">Summary<\/a><\/ul><\/ul><\/ul><\/ol>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>CPT Code 81003<\/strong><strong> &#8211; Description<\/strong><\/h2>\n\n\n\n<p>So, what does CPT code 81003 actually represent? As we mentioned in the intro, CPT 81003 refers to an automated urinalysis using a dipstick or reagent tablet. Confused about the word automated here? Let us simplify this before moving on to what exactly happens during this procedure.<\/p>\n\n\n\n<p>An automated test specifies the use of a machine for interpretation. Hence, you don\u2019t have to read and analyze the results manually. During this process, a lab technician or pathologist dips a strip or places a tablet into a freshly collected urine sample. He then shakes off the excess urine and inserts the dipstick or tablet into an automated machine, a mechanical reader.&nbsp;<\/p>\n\n\n\n<p>This machine automatically analyzes physical characteristics and chemical composition of the urine, recording elements like:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Specific Gravity<\/li>\n\n\n\n<li>Leukocytes<\/li>\n\n\n\n<li>pH<\/li>\n\n\n\n<li>Protein\u00a0<\/li>\n\n\n\n<li>Glucose<\/li>\n\n\n\n<li>Hemoglobin<\/li>\n\n\n\n<li>Ketones<\/li>\n\n\n\n<li>Nitrites<\/li>\n\n\n\n<li>Bilirubin<\/li>\n\n\n\n<li>Urobilinogen<\/li>\n<\/ul>\n\n\n\n<p>The primary purpose of urinalysis? To diagnose and monitor renal and urinary tract diseases. In short, healthcare providers use CPT code 81003 to report a routine urinalysis performed via dipstick or reagent tablet <strong>without microscopy<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Scenarios Where <\/strong><strong>CPT Code 81003<\/strong><strong> is Applicable<\/strong><\/h2>\n\n\n\n<p>Feeling overwhelmed by our long description? Let us help you understand the correct application of CPT code 81003 with real-life examples. Pay close attention to the following three scenarios:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Automated Urinalysis to Monitor a Diabetic Patient&nbsp;<\/strong><\/h3>\n\n\n\n<p>Diabetes can damage the kidneys. But did you know that only <a href=\"https:\/\/www.kidney.org\/press-room\/only-40-diabetes-patients-get-recommended-kidney-health-testing\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">40% of diabetic patients<\/a> undergo annual kidney health screenings on their doctors\u2019 recommendation? Let\u2019s use this information in our first example!<\/p>\n\n\n\n<p>Suppose a 47-year-old man with type 2 diabetes arrives at a hospital for his annual kidney screening. He is at a higher risk of developing kidney disease due to his inactive lifestyle. The healthcare provider collects the patient\u2019s urine sample and uses an automated dipstick analysis to monitor his condition.&nbsp;<\/p>\n\n\n\n<p>Since he did not use a microscope, he uses CPT code 81003 to report the procedure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Automated Urinalysis to Evaluate New Diabetic Symptoms<\/strong><\/h3>\n\n\n\n<p>Approximately <a href=\"https:\/\/www.niddk.nih.gov\/health-information\/diabetes\/overview\/preventing-problems\/diabetic-kidney-disease\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">1 out of 3 diabetic adults<\/a> in the U.S. has kidney disease. Diabetic nephropathy is one such complication that eventually leads to kidney failure. Unfortunately, it is asymptomatic until it has affected 80 to 90% of your kidneys.<\/p>\n\n\n\n<p>So, for our next example, consider a 21-year-old man with chronic type 1 diabetes. He notices swelling in his hands and feet. After some time, he also starts experiencing other symptoms, like nausea, muscle cramps, and shortness of breath. He finally visits the nearest clinic after trying and failing to manage his condition for a while.&nbsp;<\/p>\n\n\n\n<p>The healthcare provider takes the patient\u2019s detailed history, including the duration of these symptoms. Suspecting diabetic nephropathy, the physician orders an automated urinalysis for quick results. A pathologist collects the patient\u2019s urine and inserts the dipstick into a machine after dipping it in the specimen. He then bills for this automated urinalysis without microscopy with CPT code 81003.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Automated Urinalysis to Diagnose UTI<\/strong><\/h3>\n\n\n\n<p>Urinary Tract Infections (UTIs) are quite common among women, affecting <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC6502976\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">50 to 60% of women<\/a> at least once in their lifetime. Did you know that over <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC10601984\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">10% of women<\/a> are diagnosed annually with a UTI in the U.S.? Healthcare providers commonly use urinalysis to detect and manage this infection.<\/p>\n\n\n\n<p>So, for our final scenario, let\u2019s envision a 28-year-old woman with a UTI. She arrives at an urgent care clinic after experiencing painful and cloudy urination and pressure in her lower pelvis. She also tells the physician that she has been urinating more frequently than usual over the past week.<\/p>\n\n\n\n<p>The healthcare provider notes her symptoms and condition and performs an on-site urinalysis using a dipstick. He uses an automated reader for quick results and bills for the procedure using CPT code 81003.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Applicable Modifiers for <\/strong><strong>CPT Code 81003<\/strong><\/h2>\n\n\n\n<p>Here are the most frequently used modifiers with CPT code 81003:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Modifier QW<\/strong><\/h3>\n\n\n\n<p>Did you perform an automated urinalysis in your clinic under the CLIA certificate of waiver?
