D36.1 vs Q85.0
D36.1 (Benign neoplasm of peripheral nerves and autonomic nervous system) compared with Q85.0 (Neurofibromatosis (nonmalignant)), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. D36.1 carries an Excludes1 note covering Q85.0: “neurofibromatosis (Q85.0-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
