Question 1

What is ICD-10 code H49.883?

Accepted Answer

H49.883 is the ICD-10-CM diagnosis code for other paralytic strabismus, bilateral. A condition where the muscles controlling eye movement are paralyzed or weakened in both eyes, causing both eyes to turn inward or outward involuntarily. H49.883 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of ocular muscles, binocular movement, accommodation and refraction (h49-h52).

H49.883 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.

Use this code only when both eyes are affected; if only one eye is involved, use the unilateral codes.

H49.883 has no payable CMS-HCC V28 mapping in the final FY2026 CMS file.

Question 3

Is H49.883 billable?

Accepted Answer

Yes. H49.883 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. H49.883 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

Question 4

Which HCC does H49.883 map to under V28?

Accepted Answer

H49.883 has no payable CMS-HCC V28 mapping in the final FY2026 CMS file.

Question 5

What RAF reference is published for H49.883?

Accepted Answer

H49.883 has no V28 reference coefficient because the final FY2026 source verifies no payable V28 mapping.

Question 6

What is the V28 vs V24 difference for H49.883?

Accepted Answer

H49.883 has verified no payable V28 mapping in the final FY2026 source. Select a historical effective period before making any V24 comparison.

Question 7

What documentation supports H49.883?

Accepted Answer

Use this code only when both eyes are affected; if only one eye is involved, use the unilateral codes Document whether the condition is symmetric or asymmetric between the two eyes H49.883 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 H49.883 be a primary diagnosis?

Accepted Answer

Yes. H49.883 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 H49.883?

Accepted Answer

No Excludes1 note applies to H49.883 or its category in the FY2026 tabular, so there is no code the classification forbids alongside it. 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 11 more (see the notes on this page); those are separate conditions that may be reported together with H49.883 when both are documented.
