About coding lymphoid granulomatosis

The ICD-10-CM code for lymphoid granulomatosis is C83.8 (Other non-follicular lymphoma).

Within C83, choose C83.8 (Other non-follicular lymphoma) only when documentation doesn't support a more specific option: small cell B-cell lymphoma (C83.0), Mantle cell lymphoma (C83.1), diffuse large B-cell lymphoma (C83.3), lymphoblastic (diffuse) lymphoma (C83.5), Burkitt lymphoma (C83.7) and non-follicular (diffuse) lymphoma, unspecified (C83.9).

To report this condition, pick the subcode that matches the documentation: C83.80 (unspecified site), C83.81 (lymph nodes of head, face, and neck), C83.82 (intrathoracic lymph nodes), C83.83 (intra-abdominal lymph nodes), C83.84 (lymph nodes of axilla and upper limb), C83.85 (lymph nodes of inguinal region and lower limb), C83.86 (intrapelvic lymph nodes), C83.87 (spleen) and 3 more.

Don't report C83.8 together with the conditions in its Excludes1 note: mediastinal (thymic) large B-cell lymphoma (C85.2-) and T-cell rich B-cell lymphoma (C83.3-).

Don't confuse with (Excludes1 for C83.8)

  • mediastinal (thymic) large B-cell lymphoma (C85.2-)
  • T-cell rich B-cell lymphoma (C83.3-)
