About D39.2

D39.2 is the ICD-10-CM diagnosis code for neoplasm of uncertain behavior of placenta. It belongs to category D39 (neoplasm of uncertain behavior of female genital organs), block D37-D48 (neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes) and chapter 2 (neoplasms). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within D39 (neoplasm of uncertain behavior of female genital organs), D39.2 is specifically for neoplasm of uncertain behavior of placenta. Related codes cover uterus (D39.0), ovary (D39.1), other specified female genital organs (D39.8) and female genital organ, unspecified (D39.9).

Don't report D39.2 together with the conditions in its Excludes1 note: hydatidiform mole NOS (O01.9).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 731 (Uterine and Adnexa Procedures for Malignancy with MCC, relative weight 3.5478), DRG 732 (Uterine and Adnexa Procedures for Malignancy with CC, relative weight 1.9208), DRG 733 (Uterine and Adnexa Procedures for Malignancy without CC/MCC, relative weight 1.4324), DRG 754 (Malignancy, Female Reproductive System with MCC, relative weight 1.8092), DRG 755 (Malignancy, Female Reproductive System with CC, relative weight 1.149) and DRG 756 (Malignancy, Female Reproductive System without CC/MCC, relative weight 0.8645), in MDC 13 (Diseases and Disorders of the Female Reproductive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

The Medicare Code Editor treats this as a maternity diagnosis, expected only for patients age 9 through 64.

It is on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 236.1 (neoplasm of uncertain behavior of placenta).
