Oncology News Central (ONC)Updated ICD-10-CM Oncology Codes Announced: Important Changes to Know

Are You Prepared for the New ICD-10-CM Oncology Codes?


Oncology practices are set to experience changes with the recent updates to the ICD-10-CM codes. The CDC has made significant modifications to the code set, which will come into effect on October 1, 2023. These changes aim to provide more precise diagnostic information, especially in the realm of oncology.

Key Points:

  • The CDC has made more than 400 changes to the ICD-10-CM code set, effective from October 1, 2023.
  • New family history codes have been introduced, such as:
    • Z83.71 (Family history of colon polyps)
    • Z83.711 (Family history of hyperplastic colon polyps)
    • Z83.718 (Other family history of colon polyps)
    • Z83.719 (Family history of colon polyps, unspecified)
  • These family history codes can support medical necessity for specific screening tests.
  • Updates have been made to the Neoplasms section, including a new code for familial adenomatous polyposis (FAP) – D13.91.
  • Desmoid tumors now have distinct ICD-10-CM codes, such as D48.110 (Desmoid tumor of head and neck) and D48.119 (Desmoid tumor of unspecified site).

Additional Points:

  • Betty A. Hovey emphasizes the importance of Z codes in providing context and justifying specific screenings or preventive measures.
  • Dreama Sloan-Kelly, MD, highlights the significance of documenting factors like family history to demonstrate additional risk factors.
  • The ICD-10-CM Coordination and Maintenance Committee notes that the new FAP code will aid in research and screening protocols.
  • Updated ICD-10-CM Official Guidelines have been released, including new rules for reporting follow-up encounters post-cancer treatment.

Conclusion:

  • Although the recent updates introduce several new codes relevant to oncology, it’s crucial for practices to familiarize themselves with all the new, deleted, and revised ICD-10-CM codes before their implementation in October.

“Family history Z codes can be used to support medical necessity for certain screening tests, if the code is relevant to the patient’s current health care encounter. While Z codes may not always be required as tertiary diagnoses, they can provide valuable context, especially when they help to justify the need for specific screening tests or additional preventive measures.”
