Questions About Z85.72Overview
Is Z85.72 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report personal history of non-Hodgkin lymphomas on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does Z85.72 group to?
On inpatient claims, personal history of non-Hodgkin lymphomas maps to MS-DRG 826, 827, 828, 829, 830, 843, 844, 845, with relative weights from 0.8516 to 4.6778 depending on complications. Higher weights mean higher Medicare reimbursement.
Can Z85.72 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because personal history of non-Hodgkin lymphomas describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
