ICD 10 Coding for Kidney Transplant Kidney transplant status Z94.0 Patients who have undergone kidney transplant may still have some form of chronic kidney disease because the kidney transplant may not fully restore kidney function. Therefore, the presence of CKD alone does not constitute transplant complication.
Code First any associated: diabetic chronic kidney disease (E08.22, E09.22, E10.22, E11.22, E13.22) hypertensive chronic kidney disease (I12.-, I13.-) Use Additional code to identify kidney transplant status, if applicable, (Z94.0) Chronic kidney disease (CKD)
Patients who have undergone kidney transplant may still have some form of chronic kidney disease because the kidney transplant may not fully restore kidney function. Therefore, the presence of CKD alone does not constitute transplant complication.
Patient presents status post left kidney transplant. There is still documented chronic kidney disease (CKD) due to the patient only having one functioning kidney. This would NOT be coded as a complication of the transplanted kidney unless the physician states that there is a complication of the transplant.
Renal calcineurin inhibitor (CNI) toxicity is a frequent side effect of immunosuppression with CNIs in solid organ transplantation, leading to acute and chronic renal failure.
Brief Summary: Calcineurin inhibitors (CNI), a potent immunosuppressive drug used in kidney transplant recipients to prevent graft rejection, may cause renal impairment.
ICD-10 code Z94. 4 for Liver transplant status is a medical classification as listed by WHO under the range - Factors influencing health status and contact with health services .
Tacrolimus may decrease kidney function, usually if blood levels of tacrolimus are too high. This is why blood work is checked frequently to adjust the dosage of tacrolimus.
The CNIs in current clinical use include CsA and tacrolimus (TAC). While CsA and TAC differ in their molecular structure and intracellular binding characteristics, their immunosuppressive properties result from inhibition of a calcium- and calmodulin-dependent phosphatase protein or calcineurin.
Calcineurin inhibitors, which can be instrumental in preventing organ rejection in transplant patients, also can cause hypertension and kidney problems.
Orthotopic liver transplantation (OLT) involves the substitution of a diseased native liver with a normal liver (or part of one) taken from a deceased or living donor.
Status 1A patients have acute (sudden and severe onset) liver failure and are not likely to live more than a few days without a transplant. Status 1B is reserved for very sick, chronically ill patients younger than 18 years old. Less than one percent of liver transplant candidates are Status 1A and 1B at any one time.
CPT® 47135, Under Liver Transplantation Procedures The Current Procedural Terminology (CPT®) code 47135 as maintained by American Medical Association, is a medical procedural code under the range - Liver Transplantation Procedures.
No treatment recommendations exist for tacrolimus toxicity, as hemodialysis and plasma exchange are ineffective and other modalities such as gastric lavage and activated charcoal are only minimally effective and must be given early after administration [5, 19, 20].
The calcineurin inhibitors cyclosporin A (CsA) and tacrolimus (FK506) are associated with dose- and efficacy-limiting adverse events, including nephrotoxicity, which may diminish their overall benefits for long-term graft survival.
Vasospasm leading to reduced glomerular filtration appears to be a key element in the vascular toxicity tacrolimus and cyclosporine (28). The principal associated morphologic finding is arteriolar myocyte vacuolization, which may reflect a direct toxic effect bf the drug on smooth-muscle cells.
Calcineurin inhibitors are immunosuppressants used to manage autoimmune conditions including but not limited to lupus nephritis, idiopathic inflammatory myositis, interstitial lung disease, atopic dermatitis, and many more. In addition, they are used as mainstays for immunosuppression in solid organ transplants.
Calcineurin is a ubiquitous serine/threonine protein phosphatase. It plays many important physiological roles including T-cell activation, cell cycle control, muscle and heart functions, transcription regulation, learning and memory, and apoptosis.
It is concluded that tacrolimus is metabolized by cytochrome CYP3A enzymes in the small intestine. The rate of the CYP3A enzymatic activities varies about 5 times from patient to patient, and drugs that interfere with the in vitro metabolism of tacrolimus in the liver also inhibit its small intestinal metabolism.
The 2022 edition of ICD-10-CM N18.9 became effective on October 1, 2021.
Impairment of health or a condition of abnormal functioning of the kidney.
A disorder characterized by gradual and usually permanent loss of kidney function resulting in renal failure.
The end-stage of chronic renal insufficiency. It is characterized by the severe irreversible kidney damage (as measured by the level of proteinuria) and the reduction in glomerular filtration rate to less than 15 ml per min (kidney foundation: kidney disease outcome quality initiative, 2002). These patients generally require hemodialysis or kidney transplantation.
This damage may leave kidneys unable to remove wastes. Causes can include genetic problems, injuries, or medicines. You are at greater risk for kidney disease if you have diabetes, high blood pressure, or a close family member with kidney disease. chronic kidney disease damages the nephrons slowly over several years.
A common complication of kidney transplant is rejection of the transplanted organ. The body’s immune system, or defense mechanism, recognizes that something foreign is in the body and tries to destroy it
Diabetes mellitus, hypertension, cystic kidney disease, urologic conditions, and external causes such as trauma and toxins, all may cause kidney failure. When kidneys cease to filter wastes and extra fluid from the bloodstream, renal failure is considered to be permanent and consideration must be given to hemodialysis and/or kidney transplantation.
Consider 996.81 Complications of transplanted kidney versus V42.7. Kidney replaced by transplant. Assign V42.7 only if there is no complication of the kidney transplant. Code V42.7 is never used with 996.81. V codes are status codes used to classify certain conditions that may have an impact on the patient’s health status. It is appropriate to assign 996.81 when the kidney transplant is being rejected by the patient, or if there are any other complications or diseases that affect the function of the transplant.
It is appropriate to assign 996.81 when the kidney transplant is being rejected by the patient, or if there are any other complications or diseases that affect the function of the transplant. You must assign two codes to completely describe the impact on the transplanted kidney.
Kidney transplantation is a treatment option for most patients with End Stage Renal Disease (ESRD). The procedure may be deceased-donor (cadaveric) or living-donor transplantation. Living-donor renal transplants may be genetically related (living-related) or non-related (living-unrelated) transplants.
A kidney transplant may not fully restore function to the kidney, and some residual kidney disease could be present. Without the link provided by the physician, coders should report V42.7 with an additional code for the CKD. Physicians may also document in the medical record of the post-kidney transplant recipient ESRD.
Although transplant-associated renal dysfunction is often multifactorial, calcineurin inhibitor (CNI) nephrotoxicity is thought to be a major contributor. Chronic allograft nephropathy is the most common cause of late renal allograft loss, due in large part to CNI toxicity.
In the non-transplant population, the presence of hyperlipidemia has been shown to independently associate with—and likely induce and potentiate—kidney disease. For example, epidemiologic data from the Physician’s Health Study and the Atherosclerosis Risk in Communities Study ( Kidney Int. 2000;58:293-301) show that aberrations in baseline lipid profiles in apparently healthy men independently predict renal dysfunction after a mean follow-up of 14 and three years, respectively.
In some regard, lung transplant patients tend to be ideal subjects for the study of transplant-related kidney disease because immunologic injury to the lungs, in the absence of multisystem organ failure, does not directly impact renal function. Immunologic injury associated with kidney, cardiac, or liver allografts, however, has a definite effect on kidney function via renal interstitial inflammation, cardiorenal physiology, and hepatorenal physiology mechanisms, respectively.
Similarly, diabetic patients enrolled in the Early Treatment Diabetic Retinopathy Study who had dyslipidemia at time of study entry had a significantly higher risk of progressing to end-stage renal disease after controlling for other known risk factors ( Kidney Int. 2004;66:1173-1179).
Support for this theory is demonstrated by in vitro studies showing that exposure to CNIs caused vasoconstriction of isolated rat renal arteries only in the presence of intact endothelium ( J Auton Pharmacol. 2001; 21:205-210). This alteration in renal hemodynamics can be reversible upon discontinuation of the CNI. With chronic exposure, however, the reduction in renal blood flow, in addition to other direct toxic CNI effects on resident renal cells, ultimately leads to progressive irreversible kidney damage.
Additionally, we also showed that the pace of kidney function decline within the first post-transplant month was faster in hyperlipidemic recipients. Knowing that changes in kidney function early after transplant are more likely reflective of the endothelium-dependent hemodynamic alterations induced by CNIs, we hypothesize that the presence of hyperlipidemia either induces—or is at least a marker of—endothelial dysfunction that exacerbates the renal hypoperfusion caused by CNI therapy.
If a complication resulting from the transplant (e.g., failure or rejection) is clearly documented, it would be appropriate to code the complication of kidney transplant from subcategory T86.1-.
In ICD-10-CM, more than one code is required for patients with diabetic CKD. A combination code indicating the type of diabetes with diabetic CKD, along with a code identifying the stage of CKD.#N#Based on the type of diabetes, a code would be assigned: 1 For category N18, CKD, there is an instructional note to code first any associated diabetic CKD (E08.22, E09.22, E10.22, E11.22, E13.22). Category N18 would be reported after the diabetes code, as secondary, to specify the stage of CKD (N18.1-N18.6, N18.9). 2 It is also advised to use an additional code to identify dialysis status (Z99.2), if applicable. Code N18.6, end-stage renal disease, is to be reported for CKD that requires chronic dialysis. 3 In ICD-10-CM, there is an assumed cause and effect relationship between diabetes and CKD when both conditions are documented in the medical record. However, if documentation specifies that diabetes is not the underlying cause of CKD, it should not be coded as a diabetic complication.
Encounters where both a stage of CKD and ESRD are documented, report N18.6, only.
Diagnosing CKD involves identifying an individual’s glomerular filtration rate (GFR) which is a measure of their kidney function levels. These levels are defined as stages 1 through 5, increasing with severity (stage 5 = kidney failure).
It is also advised to use an additional code to identify dialysis status (Z99.2), if applicable. Code N18.6, end-stage renal disease, is to be reported for CKD that requires chronic dialysis.
Patients with a kidney transplant may still suffer some type of CKD as the transplant may not completely reinstate kidney function. Thus, having CKD alone does not mean that there is a transplant complication.
The ICD-10-CM code book does not have a hypertension table in the index. One reason is the reference to terms malignant and benign hypertension were removed as they were considered outdated. All three previous designations in ICD-9 are now reported with just one ICD-10 code for essential hypertension, code I10.
