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

Z94.82 is a billable ICD-10-CM diagnosis code for intestine transplant status. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 951. 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 10 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 intestine. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Organ transplant status.

For Medicare Advantage risk adjustment, Z94.82 maps to CMS-HCC Category 77 (Intestine Transplant Status/Complications) under the V28 model, adding a risk factor of about 1.172 for a community, non-dual, aged beneficiary in payment year 2027.

Medicare Code Editor checks that affect claim validity for Z94.82.

There are selected codes that describe a circumstance which influences an individual's health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.

Notes

General instructions on how these codes are used.

From Chapter 21 (Z00-Z99) Factors influencing health status and contact with health services applies to 1,425 codes
  • 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.

Organ Transplantation

You may need an organ transplant if one of your organs has failed. This can happen because of illness or injury. When you have an organ transplant, doctors remove an organ from another person and place it in your body. The organ may come from a living donor or a donor who has died.

Questions About Z94.82Overview

What is the ICD-10 code for intestine transplant status?

The ICD-10-CM code for intestine transplant status is Z94.82 (sometimes written as Z9482). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is Z94.82 (Other transplanted organ and tissue status) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report intestine transplant status on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does Z94.82 group to?

On inpatient claims, intestine transplant status maps to MS-DRG 951 (other Factors Influencing Health Status), which carries a relative weight of 0.5574. Higher weights mean higher Medicare reimbursement.

Is Z94.82 a CC or MCC?

CMS lists Z94.82 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 10 closely related codes in its exclusion list.

Can Z94.82 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because intestine transplant status describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

What HCC is Z94.82?

Z94.82 (intestine transplant status) maps to CMS-HCC Category 77 (Intestine Transplant Status/Complications), commonly written as HCC 77, 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 Z94.82 risk-adjust for Medicare Advantage payment?

Yes. When documented and reported on a Medicare Advantage encounter, Z94.82 adds a risk adjustment factor of about 1.172 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 1.172 to 6.301 depending on the payment segment). HCC 77 sits at the top of its hierarchy, so no other condition category supersedes it. See the full factor table on the HCC 77 category page.
