Patients require extra care from healthcare professionals because their kidney function has declined to the point that the kidneys can no longer function on their own. A patient with end-stage renal failure must receive dialysis or kidney transplantation to survive for more than a few weeks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nephrologists cannot let denials or reduced reimbursements negatively impact the quality of care in these situations. Therefore, they must master nephrology billing and coding, especially the coding of ESRD services represented by codes like CPT code 90961.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Curious about the specifics of this code?

Nephrologists who oversee dialysis patients in outpatient settings typically bill this code.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This code refers to the treatment of patients with ESRD who are 20 years or older. The patient must visit a nephrologist or any other qualified healthcare provider each month for dialysis-related management services. For this particular code, the patient is seen in person by the clinician two or three times a month.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Note that CPT 90961 falls under the monthly capitation payment (MCP) model. Hence, the provider is only paid once per month, regardless of the number of encounters in a month.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Scenarios Where <\/strong><strong>CPT Code 90961<\/strong><strong> is Applicable<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Here are some instances of adult ESRD patients for whom the provider may bill management services using CPT code 90961.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Hemodialysis<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Hemodialysis is a life-sustaining treatment for renal failure. It is used to replace the damaged kidneys by eliminating waste and extra fluid from the blood using a machine and a specific filter known as a dialyzer (artificial kidney).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Hence, let&#8217;s suppose a 22-year-old patient undergoing in-center hemodialysis visits the nephrologist multiple times during the month due to fluctuating blood pressure and dialysis access complications. The physician performs three face-to-face evaluations during the month.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since the patient is over 20 years old and has received at least two monthly visits, CPT code 90961 is appropriately reported.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>ESRD Patient with Multiple Dialysis Complications<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Suppose a 45-year-old ESRD patient has multiple complications, such as high blood pressure, electrolyte imbalance, and fatigue during dialysis treatment. The nephrologist orders him to visit the center twice a month to closely monitor the patient\u2019s condition, adjust treatment, and coordinate care with the dialysis center staff.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here, the physician must bill CPT code 90961 because the ESRD patient visited the kidney care center two times in a month for management services.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Frequent Monitoring After Dialysis Prescription Changes<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Suppose a nephrologist changes a 33-year-old patient\u2019s dialysis regimen due to inadequate toxin clearance and worsening symptoms. He demands that the patient see him thrice a month to assess progress, plan treatment modifications, analyze lab results, and ensure the new dialysis schedule is working.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this case, the CPT code 90961 is applicable because the physician required two to three monthly visits (face-to-face) for ESRD management.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Applicable Modifier for <\/strong><strong>CPT Code 90961<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The following is an applicable modifier for CPT code 90961.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Modifier 59&nbsp;<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">CPT code 90961 cannot be billed with another procedural code without the correct modifier. Apply <a href=\"https:\/\/medibillmd.com\/blog\/modifier-51-vs-59\/\" target=\"_blank\" rel=\"noreferrer noopener\">modifier 59<\/a> or the appropriate X-modifier (<a href=\"https:\/\/medibillmd.com\/blog\/modifier-xe\/\">XE<\/a>, <a href=\"https:\/\/medibillmd.com\/blog\/xs-modifier\/\" target=\"_blank\" rel=\"noreferrer noopener\">XS<\/a>, <a href=\"https:\/\/medibillmd.com\/blog\/modifier-xp\/\" target=\"_blank\" rel=\"noreferrer noopener\">XP<\/a>, <a href=\"https:\/\/medibillmd.com\/blog\/modifier-xu\/\" target=\"_blank\" rel=\"noreferrer noopener\">XU<\/a>) when another distinct service was performed on the same day as the ESRD management service. You must include the clinical justification of both services in your supporting documentation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>CPT Code 90961<\/strong><strong> \u2013 Billing &amp; Reimbursement Guidelines<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Proper billing is not just about applying the right code. Your reimbursement also depends on the documentation and compliance with the payer policies. Here are some billing guidelines you must follow to bill CPT code 90961 accurately.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Ensure Proper Documentation<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The fundamental prerequisite for reimbursement is accurate documentation. The patient&#8217;s demographics and medical condition must be accurately mentioned. Use a precise ICD-10 code that accurately reflects the patient&#8217;s condition and indicates the medical necessity of the management services.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Additionally, physicians are required to include the following information in the documentation of CPT code 90961:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Treatment date and time<\/li>\n\n\n\n<li>Physician evaluation<\/li>\n\n\n\n<li>Dialysis and medication management<\/li>\n\n\n\n<li>Treatment plan adjustments<\/li>\n\n\n\n<li>Coordination of care<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Be Mindful of Billing Frequency&nbsp;<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">As mentioned above, CPT code 90961 is a monthly capitation payment code that can be used to bill each patient once a month. This code is used to indicate the total dialysis care management provided in a month, so you cannot bill 90961 for each visit.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Follow Payer-Specific Policies<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Medicare and other commercial\/private insurance payers may have different ESRD service reimbursement rules and rates. Hence, the professional responsible for billing and filing claims must regularly review payer policies regarding documentation, modifiers, telehealth restrictions, and visit limitations to reduce the risk of claim denials.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Final Words<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In summary, CPT code 90961 is used to bill for outpatient ESRD services two to three times a month. However, for this code to be applicable, the patient\u2019s age must be 20 years or above. Using real-world examples and relevant modifiers, we have clarified the accurate usage of this code. Additionally, our billing and reimbursement guidelines address documentation requirements, billing frequency, and compliance procedures, enabling nephrology billers to accurately bill services.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Opting for third-party <a href=\"https:\/\/medibillmd.com\/specialties\/nephrology-billing-services\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>nephrology billing services<\/strong><\/a> is another option if you want to improve the efficiency of your nephrology practice. Billing professionals at these companies may support high-quality care for patients with renal disease and maximize revenue cycle performance by adhering to ESRD insurance billing guidelines.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>End-stage renal disease (ESRD) is the last and irreversible stage of chronic kidney disease.
