About coding Stromatosis
The ICD-10-CM code for Stromatosis is D39.0 (Neoplasm of uncertain behavior of uterus).
Within D39 (neoplasm of uncertain behavior of female genital organs), D39.0 is specifically for neoplasm of uncertain behavior of uterus. Related codes cover ovary (D39.1), placenta (D39.2), other specified female genital organs (D39.8) and female genital organ, unspecified (D39.9).
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.
