2016 2017 2018 2019 Billable/Specific Code. N18.3 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2018/2019 edition of ICD-10-CM N18.3 became effective on October 1, 2018. This is the American ICD-10-CM version of N18.3 - other international versions of ICD-10 N18.3 may differ.
Chronic kidney disease (CKD) N18 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail. The 2020 edition of ICD-10-CM N18 became effective on October 1, 2019. This is the American ICD-10-CM version of N18 - other international versions of ICD-10 N18 may differ.
N18 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail. The 2022 edition of ICD-10-CM N18 became effective on October 1, 2021.
N18.32 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM N18.32 became effective on October 1, 2021.
N18. 32 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM N18. 32 became effective on October 1, 2021.
The new codes are as follows: N18. 31 CKD, Stage 3a (GFR = 45-59)
Chronic kidney disease (CKD) means your kidneys are damaged and can't filter blood the way they should. The disease is called “chronic” because the damage to your kidneys happens slowly over a long period of time. This damage can cause wastes to build up in your body. CKD can also cause other health problems.
In Stage 1 CKD, the damage to your kidneys is mild. Your kidneys are still working well, but you may have signs of kidney damage or physical damage to your kidneys. Stage 1 CKD means you have a normal estimated glomerular filtration rate (eGFR) of 90 or greater, but there is protein in your urine (i.e., your pee).
N18. 31- Chronic Kidney Disease- stage 3a. N18. 32- Chronic Kidney Disease- stage 3b.
N18. 31 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM N18. 31 became effective on October 1, 2021.
Five stages of chronic kidney diseaseStage 1 with normal or high GFR (GFR > 90 mL/min)Stage 2 Mild CKD (GFR = 60-89 mL/min)Stage 3A Moderate CKD (GFR = 45-59 mL/min)Stage 3B Moderate CKD (GFR = 30-44 mL/min)Stage 4 Severe CKD (GFR = 15-29 mL/min)Stage 5 End Stage CKD (GFR <15 mL/min)
Stage 1: Kidney damage with normal or increased GFR (>90 mL/min/1.73 m 2) Stage 2: Mild reduction in GFR (60-89 mL/min/1.73 m 2) Stage 3a: Moderate reduction in GFR (45-59 mL/min/1.73 m 2) Stage 3b: Moderate reduction in GFR (30-44 mL/min/1.73 m 2)
ICD-10 code: N18. 9 Chronic kidney disease, unspecified.
Stage 1 chronic kidney disease (CKD)Stage 2 chronic kidney disease (CKD)Stage 3 chronic kidney disease (CKD)Stage 4 chronic kidney disease (CKD)Stage 5 chronic kidney disease (CKD)
However, we know that GFR physiologically decreases with age, and in adults older than 70 years, values below 60 mL/min/1.73 m2 could be considered normal.
For a 60-year-old man, stage 1 kidney disease life expectancy will be approximately 15 years. That figure falls to 13 years, 8 years, and 6 years in the second, third, and fourth stages of kidney disease respectively. For a 60-year old woman, stage 1 life expectancy is 18 years, while stage 2 is only one year less.

A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. A GFR of 15 or lower may mean kidney failure.
However, we know that GFR physiologically decreases with age, and in adults older than 70 years, values below 60 mL/min/1.73 m2 could be considered normal.
As kidney failure advances and the estimated glomerular filtration rate (eGFR) falls below 30 milliliters per minute per 1.73 meters squared, then more symptoms may manifest such as nausea, vomiting, weight loss, poor appetite, itching, fluid weight gain, shortness of breath, lassitude and fatigue.
N18.32 is a valid billable ICD-10 diagnosis code for Chronic kidney disease, stage 3b . It is found in the 2021 version of the ICD-10 Clinical Modification (CM) and can be used in all HIPAA-covered transactions from Oct 01, 2020 - Sep 30, 2021 .
DO NOT include the decimal point when electronically filing claims as it may be rejected. Some clearinghouses may remove it for you but to avoid having a rejected claim due to an invalid ICD-10 code, do not include the decimal point when submitting claims electronically.
