About coding sensory loss
The ICD-10-CM code for sensory loss is R44.9 (Unspecified symptoms and signs involving general sensations and perceptions). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on R44.9.
Within R44, choose R44.9 (Unspecified symptoms and signs involving general sensations and perceptions) only when documentation doesn't support a more specific option: auditory hallucinations (R44.0), visual hallucinations (R44.1), other hallucinations (R44.2), hallucinations, unspecified (R44.3) and other symptoms and signs involving general sensations and perceptions (R44.8).
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.
