D37.05 vs D38.0
D37.05 (Neoplasm of uncertain behavior of pharynx) compared with D38.0 (Neoplasm of uncertain behavior of larynx), 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. D37.05 carries an Excludes1 note covering D38.0: “neoplasm of uncertain behavior of aryepiglottic fold or interarytenoid fold, laryngeal aspect (D38.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
No — do not report together. D37.05 carries an Excludes1 note covering D38.0: “neoplasm of uncertain behavior of epiglottis NOS (D38.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
No — do not report together. D37.05 carries an Excludes1 note covering D38.0: “neoplasm of uncertain behavior of suprahyoid portion of epiglottis (D38.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
No — do not report together. D38.0 carries an Excludes1 note covering D37.05: “neoplasm of uncertain behavior of aryepiglottic fold or interarytenoid fold NOS (D37.05)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
No — do not report together. D38.0 carries an Excludes1 note covering D37.05: “neoplasm of uncertain behavior of hypopharyngeal aspect of aryepiglottic fold (D37.05)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
No — do not report together. D38.0 carries an Excludes1 note covering D37.05: “neoplasm of uncertain behavior of marginal zone of aryepiglottic fold (D37.05)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
