J96.12 is a billable ICD-10-CM diagnosis code for chronic respiratory failure with hypercapnia. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 189. 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 22 closely related codes. Coders also document this condition as chronic hypercapnia. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Respiratory failure; insufficiency; arrest.
For Medicare Advantage risk adjustment, J96.12 maps to CMS-HCC Category 213 (Cardio-Respiratory Failure and Shock) under the V28 model, adding a risk factor of about 0.370 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 J96.12: its own notes plus those printed at J96 and Chapter 10. A note printed at a category, block or chapter applies to every code under it.
Applicable To
Conditions this code is used for: synonyms of the title or, for "other specified" codes, the conditions assigned to it. The list is not exhaustive.
- Chronic respiratory acidosis
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
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).

Clinical ClassificationClinical
AHRQ’s CCSR groups this code into broader clinical categories.
Clinical InformationClinical
Respiratory Failure
the significant impairment of gas exchange within the lungs resulting in hypoxia, hypercarbia, or both, to the extent that organ tissue perfusion is severely compromised. causes include chronic obstructive pulmonary disease, asthma, emphysema, acute respiratory distress syndrome, pneumonia, pulmonary edema, pneumothorax, and congestive heart failure. treatment requires intubation and mechanical ventilation until the time the lungs recover sufficient function.
Patient EducationClinical
Respiratory Failure
Respiratory failure is a condition in which your blood doesn't have enough oxygen or has too much carbon dioxide. Sometimes you can have both problems.

Questions About J96.12Overview
What is the ICD-10 code for chronic respiratory failure with hypercapnia?
The ICD-10-CM code for chronic respiratory failure with hypercapnia is J96.12 (sometimes written as J9612). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is J96.12 (Chronic respiratory failure) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report chronic respiratory failure with hypercapnia on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does J96.12 group to?
When chronic respiratory failure with hypercapnia is the principal diagnosis on an inpatient stay, it groups to MS-DRG 189 (pulmonary Edema and Respiratory Failure), which carries a relative weight of 1.2107. Higher weights mean higher Medicare reimbursement.
Is J96.12 a CC or MCC?
CMS lists J96.12 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 22 closely related codes in its exclusion list.
Can J96.12 be reported with J80?
Not as a rule. The Excludes1 note at J96, which applies to J96.12, lists "acute respiratory distress syndrome (J80)". 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 J96.12?
J96.12 (chronic respiratory failure with hypercapnia) maps to CMS-HCC Category 213 (Cardio-Respiratory Failure and Shock), commonly written as HCC 213, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 84 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 J96.12 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, J96.12 adds a risk adjustment factor of about 0.370 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.258 to 0.662 depending on the payment segment). A more severe related category (HCC 211 and HCC 212) supersedes it when both are reported. See the full factor table on the HCC 213 category page.
