ICD-10/N60.29

N60.29 ICD-10-CM Code: Fibroadenosis of unspecified breast

Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.

Inpatient Payment Groups (MS-DRG)

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43.0, Appendix B.

  • MS-DRG 600 — NON-MALIGNANT BREAST DISORDERS WITH CC/MCC (MDC 09)
  • MS-DRG 601 — NON-MALIGNANT BREAST DISORDERS WITHOUT CC/MCC (MDC 09)

A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.
