About Q83.2

Q83.2 is the ICD-10-CM diagnosis code for absent nipple. It belongs to category Q83 (congenital malformations of breast), block Q80-Q89 (other congenital malformations) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Q83 (congenital malformations of breast), Q83.2 is specifically for absent nipple. Related codes cover congenital absence of breast with absent nipple (Q83.0), accessory breast (Q83.1), accessory nipple (Q83.3), other congenital malformations of breast (Q83.8) and congenital malformation of breast, unspecified (Q83.9).

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 600 (Non-Malignant Breast Disorders with CC/MCC, relative weight 0.9975) and DRG 601 (Non-Malignant Breast Disorders without CC/MCC, relative weight 0.6017), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

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 757.6 (specified congenital anomalies of breast).
