2025 ICD-10-CM code D39.2
Neoplasm of uncertain behavior of the placenta. This includes chorioadenoma destruens and invasive hydatidiform mole.
Medical necessity is established by the presence of signs, symptoms, or imaging findings suggestive of a placental abnormality. The inability to definitively characterize the neoplasm as benign or malignant necessitates further workup and potential treatment, justifying the medical necessity of services related to diagnosis and management.
Diagnosis involves patient history, physical examination, laboratory tests (including hCG levels), and imaging studies (ultrasound, CT, MRI, PET).Dilatation and curettage (D&C) may be performed. Microscopic analysis of a biopsy is crucial but may not be definitive, requiring a second opinion from another pathology lab. Treatment may vary based on the final diagnosis and includes expectant management, hysterectomy, radiation, or chemotherapy
- 2 (Neoplasms)
- D37-D48: Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes
In simple words: This code refers to a growth in the placenta during pregnancy that doctors can't tell for sure if it's cancerous or not. Further tests and monitoring are typically needed.
Neoplasm of uncertain behavior of the placenta is a diagnosis describing a tumor in the placenta that cannot be definitively classified as benign or malignant based on available microscopic examination. The placenta is the organ that develops during pregnancy, connecting the developing fetus to the uterine wall to allow nutrient uptake, waste elimination, and gas exchange via the mother's blood supply.
Example 1: A pregnant woman presents with vaginal bleeding and an enlarged uterus. Ultrasound reveals an abnormal placental mass. Biopsy results are inconclusive, leading to the code D39.2 being assigned while awaiting further pathology review., Following a miscarriage, a patient experiences continued bleeding.A D&C is performed, and the pathology report describes a placental lesion of uncertain behavior, necessitating the use of code D39.2., A woman presents with persistent metrorrhagia months after a normal delivery. Imaging reveals a mass at the placental implantation site. Biopsy findings are indeterminate for malignancy, justifying the use of D39.2.
Documentation should include details of the patient's presentation, findings from physical examinations, imaging studies (ultrasound, CT, MRI, PET if performed), laboratory results (hCG levels), and pathology reports from biopsies. It is crucial to document the uncertainty of the diagnosis and plans for further investigation or treatment.
** Excludes1: hydatidiform mole NOS (O01.9).This code should not be assigned if the neoplasm is determined to be benign or malignant after further investigation.
