N60-N65Disorders of breast

ICD-10-CM codes N60-N65 cover disorders of breast, within diseases of the genitourinary system. The block holds 79 codes across 6 categories, of which 60 are billable and 19 are header codes that cannot be submitted on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • disorders of breast associated with childbirth (O91-O92)

What else to watch in N60-N65

  • 34 codes are laterality-specific. They come in left and right pairs, and the pair is mutually exclusive on a single site: coding both without a bilateral code is a contradiction a scrubber should catch before the payer does.
  • 48 codes are named in Medicare coverage policies. An LCD or NCD lists them as supporting medical necessity, or explicitly as not supporting it. Which applies depends on the MAC for your state.
