Is D35.00 billable?

Yes, but D35.00 is an unspecified code. D35.00 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, D35.00 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting D35.00 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from D35

The conditions below can never be reported together with D35.00 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • benign neoplasm of endocrine pancreas (D13.7)
  • benign neoplasm of ovary (D27.-)
  • benign neoplasm of testis (D29.2.-)
  • benign neoplasm of thymus (D15.0)
