ICD-10 code for mutilans rhinopharyngitis

The ICD-10-CM code for mutilans rhinopharyngitis is A66.5 (Gangosa).

Within A66 (yaws), A66.5 is specifically for Gangosa. Related codes cover initial lesions of yaws (A66.0), multiple papillomata and wet crab yaws (A66.1), other early skin lesions of yaws (A66.2), Hyperkeratosis of yaws (A66.3), Gummata and ulcers of yaws (A66.4), bone and joint lesions of yaws (A66.6), other manifestations of yaws (A66.7), latent yaws (A66.8) and 1 more.

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.
