The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) is a crucial tool in healthcare for coding diagnoses and procedures. Among the vast array of codes, Z71.3, standing for Dietary counseling and surveillance, plays a significant role in classifying patient encounters related to nutritional guidance. This article delves into the specifics of the Z71.3 diagnosis code, providing a comprehensive understanding for healthcare professionals and anyone seeking clarity on this medical classification.
What is ICD-10-CM Code Z71.3?
ICD-10-CM code Z71.3 is a billable/specific code in the medical classification system. This means it is recognized for reimbursement purposes and pinpoints a specific type of health service. Specifically, Z71.3 is used to indicate a diagnosis for dietary counseling and surveillance. This code is applicable when healthcare providers offer advice and monitoring related to a patient’s diet.

The 2025 edition of ICD-10-CM Z71.3 became effective on October 1, 2024. It’s essential for medical coders and healthcare facilities to use the most current version to ensure accurate billing and record-keeping. While this is the American ICD-10-CM version, it’s worth noting that international versions of ICD-10 Z71.3 may have variations.
Decoding “Use Additional Code” for Z71.3
In ICD-10-CM coding, certain conditions require a dual coding approach to fully represent the patient’s health situation. This is where the “use additional code” and “code first” conventions come into play. For Z71.3, the instructions mention “use additional code” for any associated underlying medical condition.
This instruction highlights a crucial aspect of medical coding: capturing the complete clinical picture. If dietary counseling and surveillance are provided due to an underlying condition, that condition should be coded first, followed by Z71.3. This sequencing provides a more detailed and accurate representation of the patient’s encounter. The “use additional code” note at the etiology code and a “code first” note at the manifestation code ensure correct sequencing. Codes titled “in diseases classified elsewhere” are manifestation codes and should never be the principal diagnosis.
Synonyms and Approximate Terms for Z71.3
To further clarify the scope of Z71.3, it’s helpful to review approximate synonyms and related terms. These terms provide a broader understanding of the scenarios where this code is appropriately used. Some of the synonyms for Z71.3 include:
- Diabetes mellitus diet education done
- Dietary diabetic patient education

This extensive list emphasizes that Z71.3 encompasses a wide range of nutritional counseling and monitoring services, from specific disease-related dietary advice to general weight management and healthy eating guidance.
Present On Admission (POA) and Diagnostic Related Groups (DRG)
Present On Admission (POA) reporting is a crucial aspect of inpatient claims. POA indicates conditions present at the time of inpatient admission. However, Z71.3 is considered exempt from POA reporting. This means POA reporting is not required for this code.
Furthermore, ICD-10-CM Z71.3 is grouped within Diagnostic Related Group(s) (MS-DRG v42.0). DRGs are used to classify hospital cases and are essential for reimbursement and hospital performance analysis.
Code History of Z71.3
Understanding the code history provides context and shows the stability of this code within the ICD-10-CM system. Z71.3 was introduced as a new code in 2016 (effective October 1, 2015), marking the first year of the non-draft ICD-10-CM. Since its introduction, there have been no changes to the Z71.3 code through the 2025 edition. This stability indicates the code’s consistent relevance and application in medical coding.
Conclusion
In summary, the Z71.3 diagnosis code is a vital component of ICD-10-CM, specifically designed for Dietary counseling and surveillance. It is a billable and specific code used for a wide array of nutritional guidance services. Understanding its synonyms, the “use additional code” instruction, POA exemption, DRG grouping, and code history provides a comprehensive view of its application. For accurate medical coding and billing related to dietary and nutritional services, Z71.3 is the designated and appropriate ICD-10-CM code.
