About R29.891
R29.891 is the ICD-10-CM diagnosis code for ocular torticollis. 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 R29.89 (other symptoms and signs involving the musculoskeletal system), R29.891 is specifically for ocular torticollis. Related codes cover loss of height (R29.890) and other symptoms and signs involving the musculoskeletal system (R29.898).
Don't report R29.891 together with the conditions in its Excludes1 note: congenital (sternomastoid) torticollis Q68.0, psychogenic torticollis (F45.8), spasmodic torticollis (G24.3), torticollis due to birth injury (P15.8) 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 551 (Medical Back Problems with MCC, relative weight 1.6358) and DRG 552 (Medical Back Problems without MCC, relative weight 0.9584), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), 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 has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 781.93 (ocular torticollis).
