Which MS-DRGs does J15.212 group to?
J15.212 sits in MDC 04 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 177Respiratory Infections and Inflammations with MCCmedical
- 178Respiratory Infections and Inflammations with CCmedical
- 179Respiratory Infections and Inflammations without CC/MCCmedical
As a secondary diagnosis, J15.212 is a major complication or comorbidity (MCC), which can move a stay into a higher-paying DRG.
How is J15.212 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to J15.212. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Pneumonia › MRSA (acute) (double) (migratory) (purulent) (septic) (unresolved)
- Pneumonia › staphylococcal › aureus › methicillin resistant (acute) (double) (migratory) (purulent) (septic) (unresolved)
- Pneumonia › in › Staphylococcus › aureus › methicillin resistant (acute) (double) (migratory) (purulent) (septic) (unresolved)
Excludes1 — never code together — inherited from J15
The conditions below can never be reported together with J15.212 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Code first — inherited from J15
The underlying condition below must be sequenced before J15.212. J15.212 describes a manifestation and cannot be the principal or first-listed diagnosis.
Use additional code — inherited from Chapter 10
Report an additional code alongside J15.212 to fully describe the condition. J15.212 is sequenced first.
Use additional code — inherited from J09-J18
Report an additional code alongside J15.212 to fully describe the condition. J15.212 is sequenced first.
- code, if applicable, to identify resistance to antimicrobial drugs (Z16.-)
Excludes2 — not included here — inherited from Chapter 10
The conditions below are not part of J15.212, but a patient may have both at the same time. When documentation supports it, J15.212 and the excluded code may both 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)
Excludes2 — not included here — inherited from J09-J18
The conditions below are not part of J15.212, but a patient may have both at the same time. When documentation supports it, J15.212 and the excluded code may both be reported.
Code also — inherited from J15
Two codes may be needed to describe the condition fully. Whether J15.212 is sequenced first depends on the reason for the encounter.
How long has J15.212 existed?
J15.212 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
