About D10.5
D10.5 is the ICD-10-CM diagnosis code for benign neoplasm of other parts of oropharynx. It belongs to category D10 (benign neoplasm of mouth and pharynx), 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 D10, choose D10.5 (other parts of oropharynx) only when documentation doesn't support a more specific option: lip (D10.0), tongue (D10.1), floor of mouth (D10.2), other and unspecified parts of mouth (D10.3), tonsil (D10.4), nasopharynx (D10.6), hypopharynx (D10.7) and pharynx, unspecified (D10.9).
Don't report D10.5 together with the conditions in its Excludes1 note: benign neoplasm of epiglottis NOS (D14.1) and benign neoplasm of epiglottis, suprahyoid portion (D14.1).
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 210.6 (benign neoplasm of other parts of oropharynx).
