What is the ICD-10 code for raised antibody titer?
The ICD-10-CM code for raised antibody titer is R76.0 (sometimes written as R760). It is billable on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Is R76.0 (Other abnormal immunological findings in serum) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report raised antibody titer on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does R76.0 group to?
When raised antibody titer is the principal diagnosis on an inpatient stay, it groups to MS-DRG 814, 815, 816, with relative weights from 0.6320 to 2.1267 depending on complications. Higher weights mean higher Medicare reimbursement.
Can R76.0 be a principal diagnosis?
Use it with care. This is a symptom code, so once a definitive diagnosis explaining the raised antibody titer is established, that condition takes the principal position instead.
What is the ICD-9 equivalent of R76.0?
Under the General Equivalence Mappings, raised antibody titer converts to ICD-9-CM 795.79 (oth unspcf nspf imun fnd). The mapping is approximate, so confirm the match fits the documentation.
