The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) is a crucial system in healthcare for coding diagnoses and procedures. Within this system, code Z94.4, Liver transplant status, plays a vital role. This article delves into the specifics of the Z94.4 diagnosis code, offering a comprehensive understanding for healthcare professionals and anyone seeking clarity on medical diagnosis codes.
Decoding ICD-10-CM Code Z94.4
ICD-10-CM code Z94.4 is designated as a billable and specific code. This means it is precise enough to be used for reimbursement purposes in medical billing. The code officially came into effect on October 1, 2024, for the 2025 edition of ICD-10-CM. It’s important to note that Z94.4 is the American version, and international versions of ICD-10 Z94.4 might have variations.

Annotations and Cross-References Related to Z94.4
In the ICD-10-CM system, codes are often interconnected through annotations. For Z94.4, these annotation back-references point to codes that include various notes relevant to liver transplant status. These annotations can be categorized as:
- Applicable To: Conditions or situations where Z94.4 is appropriately used.
- Code Also: Codes that should be used in conjunction with Z94.4 to provide a more complete clinical picture.
- Code First: Underlying condition that should be coded before Z94.4.
- Excludes1 & Excludes2: Conditions that are either mutually exclusive with Z94.4 (Excludes1) or not included within Z94.4 but may occur with it (Excludes2).
- Includes: Conditions that are specifically included under the Z94.4 code.
- Note: Additional guidance or clarification regarding the use of Z94.4.
- Use Additional: Instructions to use another code to provide further details.
These annotations ensure accurate and comprehensive coding, reflecting the complexity of medical conditions and patient histories.
Synonyms and Clinical Context of Z94.4
Understanding the synonyms for Z94.4 helps in recognizing the code in different clinical documentations. Common synonyms include:
- H/o: liver recipient: Abbreviation for “history of liver recipient.”
- History of liver transplant: A straightforward description of the patient’s status.
Furthermore, Z94.4 is exempt from Present On Admission (POA) reporting. POA is a crucial concept in inpatient admissions, referring to conditions present at the time of admission order. Exemption for Z94.4 means that liver transplant status is not considered a condition that needs POA reporting, simplifying administrative processes.
Diagnostic Related Groups (DRG) and Code History
ICD-10-CM codes are grouped into Diagnostic Related Groups (MS-DRG) for the purpose of classifying hospital cases and determining reimbursement. Z94.4 falls within specific MS-DRG v42.0 groups, influencing how cases involving liver transplant recipients are categorized for billing and statistical analysis.
The code history of Z94.4 shows its consistent presence in the ICD-10-CM system since its introduction in 2016. From 2016 to 2025, there have been no changes to the code, indicating its stability and established use within medical coding practices.
Z94.4 in Relation to Other Transplant Codes
Within the broader category of “Transplanted organ and tissue status” (Z94), Z94.4 specifically addresses liver transplants. It is part of a series of codes detailing the status of various transplanted organs, including:
- Z94.0: Kidney transplant status
- Z94.1: Heart transplant status
- Z94.2: Lung transplant status
- Z94.3: Heart and lungs transplant status
- Z94.5: Skin transplant status
- Z94.6: Bone transplant status
- Z94.7: Corneal transplant status
- Z94.8: Other transplanted organ and tissue status (with subcategories for bone marrow, intestine, pancreas, stem cells, etc.)
- Z94.9: Transplanted organ and tissue status, unspecified
This categorization allows for precise documentation of different transplant statuses, ensuring accurate medical records and billing.
Conclusion
In summary, diagnosis code Z94.4, Liver transplant status, is a critical component of the ICD-10-CM system. It provides a specific, billable code for documenting patients who have undergone liver transplantation. Understanding its annotations, synonyms, POA exemption, DRG grouping, and code history is essential for accurate medical coding, billing, and healthcare data analysis. For claims with service dates on or after October 1, 2015, the use of ICD-10-CM codes, including Z94.4, is mandatory, highlighting its importance in contemporary healthcare practices.
