R29.8Other symptoms and signs involving the nervous and musculoskeletal systems

R29.8 is the ICD-10-CM diagnosis code for other symptoms and signs involving the nervous and musculoskeletal systems. It belongs to category R29 (other symptoms and signs involving the nervous and musculoskeletal systems), block R25-R29 (symptoms and signs involving the nervous and musculoskeletal systems) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within R29, choose R29.8 (Other symptoms and signs involving the nervous and musculoskeletal systems) only when documentation doesn't support a more specific option: tetany (R29.0), Meningismus (R29.1), abnormal reflex (R29.2), abnormal posture (R29.3), Clicking hip (R29.4), transient paralysis (R29.5), repeated falls (R29.6), National Institutes of Health Stroke Scale (NIHSS) score (R29.7) and 1 more.

To report this condition, pick the subcode that matches the documentation: R29.81 (system) and R29.89 (system).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
