About coding Dentures fitting
The ICD-10-CM code for Dentures fitting is Z46.3 (Encounter for fitting and adjustment of dental prosthetic device).
Within Z46 (encounter for fitting and adjustment of other devices), Z46.3 is specifically for encounter for fitting and adjustment of dental prosthetic device. Related codes cover spectacles and contact lenses (Z46.0), hearing aid (Z46.1), related to nervous system and special senses (Z46.2), 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).
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 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
