- Not a Principal Diagnosis
Z94.83 is a billable ICD-10-CM diagnosis code for pancreas transplant status. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 438 through 440. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 15 closely related codes. The code is not accepted as a principal diagnosis by the Medicare Code Editor and exempt from POA reporting. Coders also document this condition as history of transplantation of pancreas. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Organ transplant status.
For Medicare Advantage risk adjustment, Z94.83 maps to CMS-HCC Category 35 (Pancreas Transplant Status) under the V28 model, adding a risk factor of about 0.949 for a community, non-dual, aged beneficiary in payment year 2027.

Medicare Risk Adjustment (HCC)Billing
Z94.83 maps to a payment category in the CMS-HCC model used to risk-adjust Medicare Advantage payments. Weights are the published community factors for payment year 2027.

Instructions from the official ICD-10-CM Tabular List that apply to Z94.83: its own notes plus those printed at Z94, block Z77-Z99, and Chapter 21. A note printed at a category, block or chapter applies to every code under it.
Includes
Further defines, or gives examples of, the content of the category.
- organ or tissue replaced by heterogenous or homogenous transplant
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
- complications of transplanted organ or tissue - see Alphabetical Index
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

A second code may be needed to fully describe the condition; the note gives no sequencing direction.
Notes
General instructions on how these codes are used.
- Z codes represent reasons for encounters. A corresponding procedure code must accompany a Z code if a procedure is performed. Categories Z00-Z99 are provided for occasions when circumstances other than a disease, injury or external cause classifiable to categories A00-Y89 are recorded as 'diagnoses' or 'problems'. This can arise in two main ways:
- (a) When a person who may or may not be sick encounters the health services for some specific purpose, such as to receive limited care or service for a current condition, to donate an organ or tissue, to receive prophylactic vaccination (immunization), or to discuss a problem which is in itself not a disease or injury.
- (b) When some circumstance or problem is present which influences the person's health status but is not in itself a current illness or injury.

Pancreas Transplantation
The pancreas is a gland behind your stomach and in front of your spine. It produces the juices that help break down food and the hormones that help control blood sugar levels. A pancreas transplant is surgery to place a healthy pancreas from a donor into a person with a diseased pancreas.

Questions About Z94.83Overview
What is the ICD-10 code for pancreas transplant status?
The ICD-10-CM code for pancreas transplant status is Z94.83 (sometimes written as Z9483). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is Z94.83 (Other transplanted organ and tissue status) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report pancreas transplant status on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does Z94.83 group to?
On inpatient claims, pancreas transplant status maps to MS-DRG 440, 438, 439, with relative weights from 0.5966 to 1.5763 depending on complications. Higher weights mean higher Medicare reimbursement.
Is Z94.83 a CC or MCC?
CMS lists Z94.83 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 15 closely related codes in its exclusion list.
Can Z94.83 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because pancreas transplant status describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
What HCC is Z94.83?
Z94.83 (pancreas transplant status) maps to CMS-HCC Category 35 (Pancreas Transplant Status), commonly written as HCC 35, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 186 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. In the Part D prescription drug model it maps to RxHCC 396.
Does Z94.83 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, Z94.83 adds a risk adjustment factor of about 0.949 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.573 to 2.740 depending on the payment segment). HCC 35 sits at the top of its hierarchy, so no other condition category supersedes it. See the full factor table on the HCC 35 category page.
