    ICD-10-CM Code For Other Neoplasms Of Uncertain Behavior Of Lymphoid Hematopoietic And Related Tissue: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group D47 includes neoplasms of lymphoid, hematopoietic and related tissue that are of uncertain behavior, such as atypical proliferations and premalignant hematologic disorders. These ICD-10-CM diagnosis codes are used to document clinical scenarios that capture disease characterization, extent of hematopoietic or lymphoid involvement, and diagnostic uncertainty affecting management. Accurate coding within the ICD-10-CM D47 group supports proper claim adjudication and complete clinical documentation for appropriate reimbursement.

    ICD-10-CM D47: Other Neoplasms Of Uncertain Behavior Of Lymphoid, Hematopoietic And Related Tissue Overview

    This group includes neoplasms of lymphoid, hematopoietic and related tissues that are classified as of uncertain behavior rather than clearly benign or malignant. It covers conditions that involve abnormal proliferations of blood‑forming or lymphoid cells where clinical behavior is not definitively established. Accurate coding matters for reimbursement because payers and the Centers for Medicare & Medicaid Services rely on specific diagnosis codes to adjudicate claims and to reflect the complexity of care provided.

    When to Use

    Use a code from this group when the medical record documents a neoplasm of lymphoid, hematopoietic or related tissue described as of uncertain behavior, atypical, or of indeterminate malignant potential. Select the most specific code that reflects the documented site, cell type, and any noted atypia or provisional diagnosis when available.
