FY27 ICD-10-CM Updates: What Administrators Need to Know

Each Oct. 1, the annual ICD-10-CM updates take effect, bringing new diagnosis codes, deleted codes, revised coding instructions, and changes to the Alphabetic Index and Tabular List. Although diagnosis coding is often viewed as the responsibility of coding staff or nurse assessment coordinators (NACs), successful implementation also requires organizational leadership. Nursing home administrators (NHAs) play an essential role in ensuring that staff have current coding resources, understand the updates, and apply them consistently.

Annual Updates Require Preparation

ICD-10-CM is updated annually to reflect advances in medicine and improve clinical specificity. As a result, coding practices that were correct one year may no longer be accurate the next.

Although the comprehensive update takes effect each Oct. 1, diagnosis code changes may also be implemented on April 1 when necessary. Because printed ICD-10-CM code books list only the October revisions, facilities should establish a process for reviewing April updates posted by the Centers for Medicare and Medicaid Services (CMS) or the Centers for Disease Control and Prevention (CDC).

NHAs play an important role in ensuring their teams keep pace with annual coding updates. With the fiscal year (FY) 2027 ICD-10-CM updates now in effect, NHAs should verify that coding staff are using current coding resources, have access to the current Official Guidelines for Coding and Reporting and annual addenda, and receive education on the new and revised codes.

Current coding resources are essential. Even when an electronic health record (EHR) is updated, coders should verify diagnosis codes in the current Tabular List to ensure all instructional notes, sequencing requirements, and coding conventions are applied correctly.

FY 2027 Highlights for Long-Term Care

Here are examples of FY 2027 updates relevant to long-term care:

• New site-specific codes for secondary malignancies of the oral cavity, larynx, and pharynx

• Expanded cardiomyopathy codes with greater clinical specificity

• New code for a personal history of Clostridioides difficile infection

• New postprocedural hypoglycemia codes

• New codes distinguishing mild (F1) from moderate (F2) hepatic fibrosis

• New site-specific codes for odontogenic sinusitis and diseases of the pelvis

• Additional anatomical specificity for osteomyelitis

• New body mass index (BMI) codes for adults with a BMI of 18.4 or lower or 18.5 to 19.9

• Revisions to instructional notes, inclusion terms, and Alphabetic Index entries that may change code selection and sequencing

  
  

For the NHA, these updates matter because even small revisions can affect code selection, sequencing, and documentation requirements that may impact facility compliance and reimbursement accuracy.

Education Is an Interdisciplinary Responsibility

Annual ICD-10-CM education should extend beyond coding staff. Nursing, rehabilitation, dietary, social services, and other disciplines provide documentation that helps identify opportunities to clarify diagnoses. However, only provider documentation supports ICD-10-CM code assignment.

Physician Engagement Supports Coding Accuracy

Documentation from other disciplines may identify clinical indicators that support greater diagnostic specificity. In this situation, coding staff can compose a compliant physician query, an objective request asking the provider to clarify the diagnosis based on the clinical evidence already documented. The goal is to improve the accuracy and completeness of the medical record, not to influence reimbursement or lead the provider to a particular diagnosis.

Administrators should work with attending physicians and the medical director to establish expectations for timely responses to compliant queries. Prompt clarification confirms that diagnoses accurately reflect the resident’s condition and supports appropriate coding on the Minimum Data Set (MDS) and claims. Educating providers on the purpose of compliant queries and incorporating them into routine clinical workflow can improve documentation quality as well as reduce coding delays.

Leadership Sets the Standard

Accurate diagnosis coding is an organizational responsibility. Facilities that implement ICD-10-CM updates successfully have processes to obtain current coding resources, educate staff, monitor implementation, and promote collaboration between coding professionals and providers.

The FY 2027 update reminds everyone involved that coding accuracy requires ongoing attention and not just on Oct. 1. By supporting education, maintaining current coding references, and fostering accurate clinical documentation, NHAs can feel confident that their facilities remain compliant while accurately reflecting the complexity of the residents they serve.
