About R29.700

R29.700 is the ICD-10-CM diagnosis code for NIHSS score 0. 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within R29.70 (NIHSS score 0-9), R29.700 is specifically for NIHSS score 0. Related codes cover 1 (R29.701), 2 (R29.702), 3 (R29.703), 4 (R29.704), 5 (R29.705), 6 (R29.706), 7 (R29.707), 8 (R29.708) and 1 more.

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.

It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.

It was added in FY2017, effective October 1, 2016.
