About 099K7ZX
099K7ZX is the ICD-10-PCS code for a drainage procedure on the nasal mucosa and soft tissue using a via natural or artificial opening approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to biopsy of nose, the ICD-9-CM procedure title it maps to (21.22).
For a different body part, codes include 09937ZX (right external auditory canal), 09947ZX (left external auditory canal), 09957ZX (right middle ear), 09967ZX (left middle ear), 09977ZX (right tympanic membrane), 09987ZX (left tympanic membrane) and 20 more.
The same procedure with a different approach is coded 099K0ZX (open), 099K3ZX (percutaneous), 099K4ZX (percutaneous endoscopic), 099K8ZX (via natural or artificial opening endoscopic) and 099KXZX (external).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It was added in FY2018, effective October 1, 2017.
