About coding septum dislocation
The ICD-10-CM code for septum dislocation is J34.2 (Deviated nasal septum).
Within J34 (other and unspecified disorders of nose and nasal sinuses), J34.2 is specifically for Deviated nasal septum. Related codes cover abscess, furuncle and carbuncle of nose (J34.0), cyst and mucocele of nose and nasal sinus (J34.1), 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).
Don't report J34.2 together with the conditions in its Excludes1 note: congenital deviated nasal septum (Q67.4).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
