CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

I69.862 is a billable ICD-10-CM diagnosis code for other paralytic syndrome following other cerebrovascular disease affecting left dominant side. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 56 through 57. The code is exempt from POA reporting. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Sequela of cerebral infarction and other cerebrovascular disease.

For Medicare Advantage risk adjustment, I69.862 maps to CMS-HCC Category 254 (Monoplegia, Other Paralytic Syndromes) under the V28 model, adding a risk factor of about 0.321 for a community, non-dual, aged beneficiary in payment year 2027.

Questions About I69.862Overview

Is I69.862 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other paralytic syndrome following other cerebrovascular disease affecting left dominant side on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does I69.862 group to?

When other paralytic syndrome following other cerebrovascular disease affecting left dominant side is the principal diagnosis on an inpatient stay, it groups to MS-DRG 57, 56, with relative weights from 1.2835 to 2.2649 depending on complications. Higher weights mean higher Medicare reimbursement.

Is I69.862 exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for other paralytic syndrome following other cerebrovascular disease affecting left dominant side on inpatient claims. The code appears in the Cerebrovascular diseases (I60-I69) range of the CMS exempt list.

Can I69.862 be reported with a code from I69.85?

Not as a rule. The Excludes1 note at I69.86, which applies to I69.862, lists "hemiplegia/hemiparesis following other cerebrovascular disease (I69.85-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

Does I69.862 need an additional code?

When the condition applies, yes. The Use Additional Code note at I69.86, which applies to I69.862, reads: code to identify type of paralytic syndrome, such as: locked-in state (G83.5); quadriplegia (G82.5-). The additional code is reported after I69.862.

What HCC is I69.862?

I69.862 (other paralytic syndrome following other cerebrovascular disease affecting left dominant side) maps to CMS-HCC Category 254 (Monoplegia, Other Paralytic Syndromes), commonly written as HCC 254, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 104 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. It does not map to any RxHCC in the Part D prescription drug model.

Does I69.862 risk-adjust for Medicare Advantage payment?

Yes. When documented and reported on a Medicare Advantage encounter, I69.862 adds a risk adjustment factor of about 0.321 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.000 to 0.365 depending on the payment segment). A more severe related category (HCC 180, HCC 181, HCC 191, HCC 192, and HCC 253) supersedes it when both are reported. See the full factor table on the HCC 254 category page.
