B74Filariasis

Non-billable headerICD-10-CM

B74 is a non-billable header ICD-10-CM code for filariasis. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • onchocerciasis (B73)
  • tropical (pulmonary) eosinophilia NOS (J82.89)

Other codes that can never be billed with B74

These codes carry an Excludes1 note pointing at B74. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading B74 alone.

  • R82.0Chyluria
  • I89Other noninfective disorders of lymphatic vessels and lymph nodes

Risk adjustment

B74 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead B74

7 child codes. Green means billable.
