About M35.08

M35.08 is the ICD-10-CM diagnosis code for Sjogren syndrome with gastrointestinal involvement. It belongs to category M35 (other systemic involvement of connective tissue), block M30-M36 (systemic connective tissue disorders) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within M35.0 (Sjogren syndrome), M35.08 is specifically for Sjogren syndrome with gastrointestinal involvement. Related codes cover unspecified (M35.00), with keratoconjunctivitis (M35.01), with lung involvement (M35.02), with myopathy (M35.03), with tubulo-interstitial nephropathy (M35.04), with inflammatory arthritis (M35.05), with peripheral nervous system involvement (M35.06), with central nervous system involvement (M35.07) and 4 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 545 (Connective Tissue Disorders with MCC, relative weight 2.3892), DRG 546 (Connective Tissue Disorders with CC, relative weight 1.1745) and DRG 547 (Connective Tissue Disorders without CC/MCC, relative weight 0.7526), 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 was added in FY2022, effective October 1, 2021.
