ICD-10 code for nasal hypertrophy

The ICD-10-CM code for nasal hypertrophy is J34.89 (Other specified disorders of nose and nasal sinuses). The official index lists 6 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J34.89.

Within J34.8, choose J34.89 (Other specified disorders of nose and nasal sinuses) only when documentation doesn't support a more specific option: nasal mucositis (ulcerative) (J34.81), nasal valve collapse (J34.82) and odontogenic sinusitis (J34.83).

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 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), DRG 156 (Other Ear, Nose, Mouth and Throat Diagnoses without CC/MCC, relative weight 0.6659) and DRG 795 (Normal Newborn, relative weight 0.2022), in MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
