What is the icd 10 code for chronic kidney disease

  • N18
  • N18.4

Your kidneys are damaged. Therefore, your kidneys have been working much too little for some time.

This is also referred to as renal insufficiency.

There are normally 2 kidneys in the body. They filter blood and create urine. They thus help to detoxify the body. Furthermore, the kidneys regulate the blood pressure and salt content in the blood, among other things.

If the kidneys are no longer working properly, they can no longer perform their tasks properly. One result of this may be that your blood pressure is too high. If the kidneys stop producing enough urine, you excrete little urine. Too much fluid then remains in the body. This fluid can then collect in the legs, for example.

The kidneys also produce messenger substances. If the kidneys no longer work properly, not enough messenger substances are produced. This can impact on the body in many ways. For example, the bones may become less solid. Not enough of the red blood pigment may be produced. The salt content and acid content in your blood may also change. Deposits may also form more rapidly in the blood vessels.

If the kidneys no longer work properly, substances can also collect in the body. These substances are normally excreted in the urine. The body can be damaged by these substances.

Additional indicator

On medical documents, the ICD code is often appended by letters that indicate the diagnostic certainty or the affected side of the body.

  • G: Confirmed diagnosis
  • V: Tentative diagnosis
  • Z: Condition after
  • A: Excluded diagnosis

  • L: Left
  • R: Right
  • B: Both sides

Further information

Note

This information is not intended for self-diagnosis and does not replace professional medical advice from a doctor. If you find an ICD code on a personal medical document, please also note the diagnostic confidence indicator.
Your doctor will assist you with any health-related questions and explain the ICD code to you in a direct consultation if necessary.

The ICD-10-CM code for Chronic Kidney Disease (CKD) Stage 3 (N18.3) has been revised for Fiscal Year 2021. The most recent update to the CMS-HCC Risk Adjustment Model has CKD Stage 3 making an impact on Risk Adjustment Factor scores. On the other hand, CKD Stage 3 is not recognized as a complication or comorbidity (CC) in the DRG world of coding.

Not only do the new codes for CKD Stage 3 give more specificity and capture more detail, but they also help to define more precisely the edge within Stage 3 at which mortality becomes the main concern.

The new codes are as follows:

  • N18.30  CKD, Stage 3 unspecified
  • N18.31  CKD, Stage 3a (GFR = 45-59)
  • N18.32  CKD, Stage 3b (GFR= 30-44)

Kidney disease is often asymptomatic and occurs just before kidney failure. About one-third of the population of older adults have CKD Stage 3. When someone is experiencing Stage 3, it means their kidneys are filtering about half of what they should be, allowing for some fluids, electrolytes, and waste to build up in the body.

CKD often starts to develop without notice. However, symptoms may appear in Stage 3. For those that do experience symptoms, these may include fatigue, swelling around the ankles or eyes, unusually light-colored urine, urinating more frequently, and loss of appetite.

Once an individual has Stage 3 CKD, it’s generally considered to be irreversible. Fortunately, the majority of Stage 3 patients do not progress to the more severe stages. Still, it is important to work with a doctor to manage the condition and gain a clear picture in regard to the GFR and kidneys. This helps to identify the need for kidney replacement therapy sooner and essentially helps to keep the patient healthier longer.

How do you code Chronic kidney disease?

CKD: Document the stage of CKD. The diagnosis of CKD cannot be coded from a GFR value alone, since it cannot imply the stage. If both a stage of CKD and ESRD are documented, assign code N18. 6 only (for ESRD).

What is the difference between ICD

N18. 31- Chronic Kidney Disease- stage 3a. N18. 32- Chronic Kidney Disease- stage 3b.

What is the ICD

ICD-10 code: N18. 4 Chronic kidney disease, stage 4.

What is ICD

N19: Unspecified kidney failure.
