HCC 37: Diabetes with Chronic Complications

HCC 37, Diabetes with Chronic Complications, is one of the 115 payment categories in the CMS-HCC V28 model. 308 ICD-10-CM codes map to it in the payment year 2027 mapping, and a documented diagnosis in the category adds a relative factor of 0.166 to the risk score of a community, non-dual, aged beneficiary (0.191 disabled, 0.280 institutional). It is overridden when a more severe category in its hierarchy is present (HCC 35, HCC 36) and it in turn overrides HCC 38.

Relative factors by segment

Each segment is a separate regression; the factor is added to the beneficiary's demographic factors and other categories, then normalized and reduced by the coding intensity adjustment before it meets the plan's base rate. A factor of 1.000 equals the expected cost of an average beneficiary.

Hierarchy

Hierarchical condition categories pay only the most severe manifestation of a disease. When HCC 35 (Pancreas Transplant Status) or HCC 36 (Diabetes with Severe Acute Complications) is also documented for the same beneficiary, HCC 37 is dropped from the score. When HCC 37 is present it drops HCC 38 (Diabetes with Glycemic, Unspecified, or No Complications), so documenting the less severe condition alongside it adds nothing to payment but still matters for the clinical record.

ICD-10-CM codes that map to HCC 37

308 codes map to this category in the PY2027 initial mapping, concentrated in the E08 (77), E10 (77), E11 (77), E13 (77) code families. Descriptions are the CMS mapping descriptions for the FY2026 code set; a code that is deleted or split in the October code update stays valid for dates of service before the change.

Where these codes sat in the V22 model

The V28 recalibration renumbered and regrouped categories; this table shows which legacy V22 categories the same ICD-10 codes belonged to, which is the quickest way to reconcile a V22-era HCC gap list with the current model.

Capturing and defending the category

A category counts for a payment year when a mapped diagnosis is documented at least once during the data collection year by an acceptable provider type at a face-to-face or audio-video encounter, and when the note shows the condition was monitored, evaluated, assessed or treated. Chronic conditions do not carry forward: a category that is not re-documented in the year drops out of the score, which is why annual wellness visits and problem-list reconciliation are where most recapture happens. Risk adjustment data validation audits sample enrollees and ask for the medical record behind each submitted category; an unsupported category is removed and, under the extrapolation rules, the error rate is applied across the contract. The QuickIntell risk adjustment product surfaces suspected and unsupported categories from the chart, and the HCC hub lists every V28 category with its factor and code count.

Frequently asked questions

Which ICD-10 codes map to HCC 37?

308 ICD-10-CM codes map to HCC 37 in the CMS PY2027 initial mapping, for example E0821 Diabetes mellitus due to underlying condition with diabetic nephropathy; E0822 Diabetes mellitus due to underlying condition with diabetic chronic kidney disease; E0829 Diabetes mellitus due to underlying condition with other diabetic kidney complication; E08311 Diabetes mellitus due to underlying condition with unspecified diabetic retinopathy with macular edema. The full list is on this page; a code counts only when it is documented at a face-to-face or video encounter in the data collection year and supported by the record.

How much does HCC 37 add to a risk score?

The V28 relative factor for HCC 37 is 0.166 for a community, non-dual, aged beneficiary, 0.186 for full-benefit dual aged, 0.191 for non-dual disabled and 0.280 for long-term institutional members. A factor of 1.000 equals the expected annual cost of an average beneficiary, so the category's share of the payment follows the plan's base rate for that segment.

Does HCC 37 count together with related categories?

No. Within a hierarchy only the most severe category is paid. HCC 37 is dropped when HCC 35 (Pancreas Transplant Status) or HCC 36 (Diabetes with Severe Acute Complications) is also present, and it drops HCC 38 when it is present.

What has to be documented for HCC 37 to be valid?

The diagnosis must be recorded by an acceptable provider type during a face-to-face or audio-video encounter in the service year, with the note showing that the condition was monitored, evaluated, assessed or treated. Risk adjustment data validation audits recover payment for categories the record does not support, so the code on the claim and the assessment in the note must match.
