About D14.1

D14.1 is the ICD-10-CM diagnosis code for benign neoplasm of larynx. It belongs to category D14 (benign neoplasm of middle ear and respiratory system), block D10-D36 (benign neoplasms, except benign neuroendocrine tumors) and chapter 2 (neoplasms). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within D14 (benign neoplasm of middle ear and respiratory system), D14.1 is specifically for benign neoplasm of larynx. Related codes cover middle ear, nasal cavity and accessory sinuses (D14.0), trachea (D14.2), bronchus and lung (D14.3) and respiratory system, unspecified (D14.4).

Don't report D14.1 together with the conditions in its Excludes1 note: benign neoplasm of epiglottis, anterior aspect (D10.5) and polyp (nonadenomatous) of vocal cord or larynx (J38.1).

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 011 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC, relative weight 5.6154), DRG 012 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CC, relative weight 4.381), DRG 013 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCC, relative weight 2.7307), DRG 154 (Other Ear, Nose, Mouth and Throat Diagnoses with MCC, relative weight 1.5921), DRG 155 (Other Ear, Nose, Mouth and Throat Diagnoses with CC, relative weight 0.9322) and DRG 156 (Other Ear, Nose, Mouth and Throat Diagnoses without CC/MCC, relative weight 0.6659), in Pre-MDC and MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat), 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 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 212.1 (benign neoplasm of larynx).
