About D76

D76 is the ICD-10-CM diagnosis code for other specified diseases with participation of lymphoreticular and reticulohistiocytic tissue. It belongs to block D70-D77 (other disorders of blood and blood-forming organs) and chapter 3 (diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: D76.1 (lymphohistiocytosis), D76.2 (infection-associated) and D76.3 (syndromes).

Don't report D76 together with the conditions in its Excludes1 note: (Abt-) Letterer-Siwe disease (C96.0), eosinophilic granuloma (C96.6), Hand-Schüller-Christian disease (C96.5), histiocytic medullary reticulosis (C96.9) and 11 more.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
