ICD-10 Code R73.01

Impaired fasting glucose

What is the code R73.01?

The ICD-10-CM code R73.01 stands for "impaired fasting glucose." Code R73.01 is an International Classification of Diseases, 10th revision, Clinical Modification (ICD-10-CM) code that healthcare providers and medical billers use to document and classify cases where patients exhibit abnormal fasting glucose levels that do not meet the criteria for a diabetes diagnosis.

Detailed description of R73.01

R73.01, impaired fasting glucose, is categorized under the ICD-10 chapter for symptoms, signs, and abnormal clinical and laboratory findings, not elsewhere classified (R00–R99). This code is specifically used when a patient's fasting blood glucose levels are higher than normal but not high enough to be classified as diabetes. The fasting glucose level typically ranges between 100 mg/dL and 125 mg/dL. It’s an important marker for identifying patients at risk for diabetes, allowing for early intervention and management to prevent the progression to type 2 diabetes.

Symptoms commonly associated with R73.01

Impaired fasting glucose (R73.01) itself is generally asymptomatic, meaning patients often do not exhibit noticeable symptoms. However, it is important to monitor for potential signs that may indicate a progression toward diabetes or other metabolic disorders. These signs can include:

  • Increased thirst
  • Frequent urination
  • Unexplained weight loss
  • Fatigue
  • Blurred vision

In absence of a definitive diagnosis, code these symptoms in addition to R73.01.

Several ICD-10-CM codes are related to R73.01 and can be used for conditions that often present similarly or are part of the same diagnostic spectrum:

  • E11.9: Type 2 diabetes mellitus without complications
  • R73.02: Impaired glucose tolerance (oral)
  • R73.03: Prediabetes
  • R73.9: Hyperglycemia, unspecified

These codes help in distinguishing between different stages and types of glucose metabolism disorders.

Appropriate usage and guidelines for R73.01

All that needs to be documented to use code R73.01 are details such as "abnormal fasting glucose" and "elevated fasting glucose" by the clinician in the assessment and plan portion of the note.

Common pitfalls in coding with R73.01

Medical coders should be aware of several common pitfalls when using R73.01:

  • Misclassification: Confusing R73.01 (impaired fasting glucose) with codes for diabetes (E11.x, E10.x) or other glucose abnormalities like R73.02 (impaired glucose tolerance) can lead to improper management plans and billing issues.
  • Insufficient documentation: Claims may be denied if fasting glucose results are unclear or missing.
  • Failure to update: If a patient develops diabetes or glucose levels normalize, update the code accordingly to avoid treatment and coverage issues.

Key resources for R73.01 coding

For accurate coding and documentation of R73.01, several resources can be invaluable:

These resources can help ensure accurate and compliant coding practices.

Conclusion

Use ICD-10 code R73.01, impaired fasting glucose, to classify and document cases where patients exhibit abnormal fasting glucose levels. Accurate usage and documentation of this code are important for proper patient management and follow-up. By understanding the detailed description, symptoms, related codes, and guidelines, healthcare providers can effectively monitor and intervene in cases of impaired fasting glucose, ultimately improving patient outcomes. Using key resources and avoiding common pitfalls can further enhance the accuracy and efficacy of coding practices.
