Accepted Answer

H47.641 is the ICD-10-CM diagnosis code for disorders of visual cortex in (due to) vascular disorders, right side of brain. Problems with the visual cortex on the right side of the brain caused by blood vessel disorders such as stroke or vascular disease. H47.641 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of optic nerve and visual pathways (h46-h47).

H47.641 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.

Code the underlying vascular disorder (stroke, aneurysm, etc.) as the primary condition.

Question 7

What documentation supports H47.641?

Accepted Answer

Code the underlying vascular disorder (stroke, aneurysm, etc.) as the primary condition Verify right-sided involvement is documented in neuroimaging or clinical assessment H47.641 is not a CMS-HCC V28 payment code in the verified current source, so MEAT is not the payment hook. Documentation still has to support the diagnosis if you report it.

Question 8

Can H47.641 be a primary diagnosis?

Accepted Answer

Yes. H47.641 carries no code-first instruction in the FY2026 tabular, so it can be the first-listed diagnosis when it is the condition chiefly responsible for the encounter and the note supports it, and it can also be reported as a secondary diagnosis. For risk adjustment the order does not matter; the V28 category is the same either way.

Question 9

Which codes cannot be reported with H47.641?

Accepted Answer

The Excludes1 note that applies to H47.641 lists injury to visual cortex S04.04-. An Excludes1 condition is not reported together with H47.641; report one or the other, unless the two conditions are unrelated, which the ICD-10-CM Official Guidelines (Section I.A.12.a) allow. The Excludes2 note lists certain conditions originating in the perinatal period (P04-P96); certain infectious and parasitic diseases (A00-B99); complications of pregnancy, childbirth and the puerperium (O00-O9A); congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99); and 7 more (see the notes on this page); those are separate conditions that may be reported together with H47.641 when both are documented.
