About coding neuropacemaker fitting
The ICD-10-CM code for neuropacemaker fitting is Z46.2 (Encounter for fitting and adjustment of other devices related to nervous system and special senses). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Z46.2.
Within Z46 (encounter for fitting and adjustment of other devices), Z46.2 is specifically for encounter for fitting and adjustment of other devices related to nervous system and special senses. Related codes cover spectacles and contact lenses (Z46.0), hearing aid (Z46.1), dental prosthetic device (Z46.3), orthodontic device (Z46.4), other gastrointestinal appliance and device (Z46.5), urinary device (Z46.6), other specified devices (Z46.8) and unspecified device (Z46.9).
The conditions in its Excludes2 note aren't part of Z46.2, but may be coded alongside it if the patient has both: encounter for adjustment and management of implanted nervous system device (Z45.4-) and encounter for adjustment and management of implanted visual substitution device (Z45.31).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
