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

T83.010A is a billable ICD-10-CM diagnosis code for breakdown (mechanical) of cystostomy catheter, initial encounter. The 7th character A marks it as an initial encounter code, used while the patient is receiving active treatment. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 698 through 700. 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 117 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Complication of genitourinary device, implant or graft, initial encounter.

T83.010A no longer risk-adjusts for Medicare Advantage: it mapped to HCC 176 under the retired CMS-HCC V24 model through payment year 2025 but maps to no category in the live V28 model. It still risk-adjusts in the PACE (CMS-HCC V22) category 176, ESRD (V21) category 176, and ESRD (V24) category 176 for payment year 2027.

Coding GuidelinesGuidance

The appropriate 7th character is to be added to each code from block Complications of genitourinary prosthetic devices, implants and grafts (T83). Use the following options for the applicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Notes

General instructions on how these codes are used.

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
  • The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.

7th Character

Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.

From T83 Complications of genitourinary prosthetic devices, implants and grafts applies to 246 codes
  • The appropriate 7th character is to be added to each code from category T83

Patient EducationClinical

Ostomy

An ostomy is surgery to create an opening (stoma) from an area inside the body to the outside. It treats certain diseases of the digestive or urinary systems. It can be permanent, when an organ must be removed. It can be temporary, when the organ needs time to heal. The organ could be the small intestine, colon, rectum, or bladder.

Questions About T83.010AOverview

What is the ICD-10 code for breakdown (mechanical) of cystostomy catheter, initial encounter?

The ICD-10-CM code for breakdown (mechanical) of cystostomy catheter, initial encounter is T83.010A (sometimes written as T83010A). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is T83.010A (Breakdown (mechanical) of cystostomy catheter) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report breakdown (mechanical) of cystostomy catheter, initial encounter on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character A in T83.010A mean?

The final character A marks the initial encounter: use it while the patient is receiving active treatment for breakdown (mechanical) of cystostomy catheter, such as an emergency visit or first evaluation.

What MS-DRG does T83.010A group to?

When breakdown (mechanical) of cystostomy catheter, initial encounter is the principal diagnosis on an inpatient stay, it groups to MS-DRG 699, 698, 700, with relative weights from 0.6740 to 1.6400 depending on complications. Higher weights mean higher Medicare reimbursement.

Is T83.010A a CC or MCC?

CMS lists T83.010A 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 117 closely related codes in its exclusion list.

Does T83.010A risk-adjust for Medicare Advantage payment?

Not for Medicare Advantage. T83.010A mapped to HCC 176 in the retired CMS-HCC V24 model, which last determined payment in 2025, but it maps to no category in the live V28 model; see all codes that no longer risk-adjust. It still risk-adjusts in the PACE (CMS-HCC V22) category 176 (Complications of Specified Implanted Device or Graft), ESRD (V21) category 176 (Complications of Specified Implanted Device or Graft), and ESRD (V24) category 176 (Complications of Specified Implanted Device or Graft).
