Understanding the intricacies of medical coding is crucial in healthcare, especially when dealing with conditions like follicular lymphoma. The Diagnosis Code For Follicular Lymphoma, specifically C82.90, within the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) system, is a vital tool for medical professionals. This article delves into the details of the C82.90 code, offering a comprehensive overview for healthcare providers and anyone seeking to understand this specific diagnostic classification.
Decoding ICD-10-CM Code C82.90
ICD-10-CM code C82.90 is designated as a billable/specific code, meaning it is precise enough to be used for reimbursement purposes. This code officially came into effect on October 1, 2015, for claims with dates of service on or after this date, replacing ICD-9-CM codes. The current version, 2025 ICD-10-CM C82.90, became effective on October 1, 2024, with no changes from previous years, indicating a stable and consistently used code within the medical coding system. It’s important to note that this is the American ICD-10-CM version, and international versions might have variations.
Synonyms and Clinical Context of C82.90
The diagnosis code C82.90, categorized under “Follicular lymphoma, unspecified, unspecified site,” encompasses several approximate synonyms that are helpful in clinical understanding. These include:
- Follicular lymphoma
- Follicular non-Hodgkin’s lymphoma
- Lymphoma, nodular
- Nodular lymphoma
These terms all refer to the same condition classified under C82.90, which is a subtype of non-Hodgkin’s lymphoma characterized by its follicular growth pattern. The “unspecified site” designation in C82.90 indicates that the location of the lymphoma is not specified within this particular code, requiring further details in patient records for comprehensive diagnosis.
Historical Stability and Related Codes
The code history of C82.90 shows its consistent use since its introduction in 2016, with no modifications through the 2025 edition. This stability underscores its established place in diagnostic coding. Furthermore, C82.90 is positioned within a range of related codes, such as C82.9 and codes from C82.82 to C82.8A and C82.91 to C82.9A. These adjacent codes specify follicular lymphoma at various sites (e.g., lymph nodes of head, face, and neck – C82.91, intrathoracic lymph nodes – C82.92) or with specific statuses like “in remission” (C82.9A). This detailed classification system allows for precise coding based on the specific presentation of follicular lymphoma.
Conclusion
In summary, the diagnosis code C82.90 is a critical identifier for follicular lymphoma, unspecified site within the ICD-10-CM system. Its specificity, billable status, and stable history make it an essential tool for accurate diagnosis, medical billing, and healthcare data management. Understanding C82.90 and its related codes is vital for healthcare professionals involved in oncology and medical coding, ensuring correct classification and treatment planning for patients with follicular lymphoma.
