J34.0Abscess, furuncle and carbuncle of nose

J34.0 is the ICD-10-CM diagnosis code for abscess, furuncle and carbuncle of nose. It belongs to category J34 (other and unspecified disorders of nose and nasal sinuses), block J30-J39 (other diseases of upper respiratory tract) and chapter 10 (diseases of the respiratory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within J34 (other and unspecified disorders of nose and nasal sinuses), J34.0 is specifically for abscess, furuncle and carbuncle of nose. Related codes cover cyst and mucocele of nose and nasal sinus (J34.1), Deviated nasal septum (J34.2), hypertrophy of nasal turbinates (J34.3), other specified disorders of nose and nasal sinuses (J34.8) and unspecified disorder of nose and nasal sinuses (J34.9).

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.

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 478.19 (other disease of nasal cavity and sinuses).
