J95.850 is a billable ICD-10-CM diagnosis code for mechanical complication of respirator. 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 3 closely related codes. Coders also document this condition as artificial ventilation finding. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Postprocedural or postoperative respiratory system complication.
For Medicare Advantage risk adjustment, J95.850 maps to CMS-HCC Category 211 (Respirator Dependence/Tracheostomy Status/Complications) under the V28 model, adding a risk factor of about 0.879 for a community, non-dual, aged beneficiary in payment year 2027.

Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to J95.850: its own notes plus those printed at J95 and Chapter 10. A note printed at a category, block or chapter applies to every code under it.
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
- encounter for respirator [ventilator] dependence during power failure (Z99.12)
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.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- smoke inhalation (T59.81-)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
Notes
General instructions on how these codes are used.
- When a respiratory condition is described as occurring in more than one site and is not specifically indexed, it should be classified to the lower anatomic site (e.g. tracheobronchitis to bronchitis in J40).

Questions About J95.850Overview
What is the ICD-10 code for mechanical complication of respirator?
The ICD-10-CM code for mechanical complication of respirator is J95.850 (sometimes written as J95850). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is J95.850 (Complication of respirator [ventilator]) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report mechanical complication of respirator on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does J95.850 group to?
When mechanical complication of respirator is the principal diagnosis on an inpatient stay, it groups to MS-DRG 951 (other Factors Influencing Health Status), which carries a relative weight of 0.5574. Higher weights mean higher Medicare reimbursement.
Is J95.850 a CC or MCC?
CMS lists J95.850 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 3 closely related codes in its exclusion list.
Can J95.850 be reported with Z99.12?
Not as a rule. The Excludes1 note on J95.850 lists "encounter for respirator [ventilator] dependence during power failure (Z99.12)". 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).
What HCC is J95.850?
J95.850 (mechanical complication of respirator) maps to CMS-HCC Category 211 (Respirator Dependence/Tracheostomy Status/Complications), commonly written as HCC 211, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 82 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 J95.850 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, J95.850 adds a risk adjustment factor of about 0.879 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.590 to 1.981 depending on the payment segment). HCC 211 sits at the top of its hierarchy, so no other condition category supersedes it. See the full factor table on the HCC 211 category page.
