What ICD-10 Codes Are Used for Elevated Creatinine?

R94.4: This code pertains to Abnormal Results of Kidney Function. It refers to conditions where the creatinine level, a significant kidney function indicator, is higher than the normal range, suggesting impaired kidney function.
N18.9: Chronic Kidney Disease, Unspecified. This code applies to cases where chronic kidney disease is present (which can cause elevated creatinine levels), but its stage is not specified.
N19: Unspecified Kidney Failure. This code refers to situations where kidney failure is evident (possibly causing elevated creatinine), but the type of failure is not indicated.
N25.9: Disorder of Kidney and Ureter, Unspecified. This code is used when there are disorders of the kidney and ureter (which may cause creatinine levels to rise), but the specific condition is not indicated.

Which Elevated Creatinine ICD Codes Are Billable?

R94.4: Yes, it's billable as it represents a specific medical condition (Abnormal Results of Kidney Function Studies) diagnosed by a healthcare provider.
N18.9: Yes, Chronic Kidney Disease, Unspecified is a billable code as it suggests a concrete medical condition.
N19: Yes, Unspecified Kidney Failure is billable as it reflects a precise diagnosis.
N25.9: Yes, this code is billable as it points to a specific disorder of the kidney and ureter.

Clinical Information

Elevated creatinine levels are often an indication of impaired kidney function. This can occur due to various conditions, including chronic kidney disease, kidney failure, or disorders of the kidney and ureter.
Creatinine is a waste product produced by muscles and excreted by the kidneys. Elevated levels may indicate that the kidneys aren't functioning correctly or effectively removing creatinine from the body.
The primary symptoms of elevated creatinine levels include fatigue, shortness of breath, confusion, and reduced urine output. However, symptoms may only appear once the condition is quite advanced.
Elevated creatinine is usually diagnosed through blood tests. In some cases, additional tests may be necessary to determine the underlying cause of the kidney dysfunction.
Treatment for elevated creatinine primarily involves managing the underlying condition causing kidney dysfunction. This might include lifestyle changes, medication, or in severe cases, dialysis or kidney transplant.

Synonyms Include:

Abnormal Kidney Function Studies
High Creatinine Levels
Impaired Kidney Function
Kidney Dysfunction
Raised Creatinine
