What does the 7th character "P" mean in S42.322P?
In S42.322P, the 7th character P means subsequent encounter for fracture with malunion. The 7th character is required for S42.322P to be a valid, complete code.
Same condition, different episode of care — switch the 7th character:

Which MS-DRGs does S42.322P group to?
S42.322P sits in MDC 08 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.
- 564Other Musculoskeletal System and Connective Tissue Diagnoses with MCCmedical
- 565Other Musculoskeletal System and Connective Tissue Diagnoses with CCmedical
- 566Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCCmedical
As a secondary diagnosis, S42.322P is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from S42
The conditions below can never be reported together with S42.322P on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- traumatic amputation of shoulder and upper arm (S48.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside S42.322P to fully describe the condition. S42.322P is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of S42.322P, but a patient may have both at the same time. When documentation supports it, S42.322P and the excluded code may both be reported.
Excludes2 — not included here — inherited from S40-S49
The conditions below are not part of S42.322P, but a patient may have both at the same time. When documentation supports it, S42.322P and the excluded code may both be reported.
Excludes2 — not included here — inherited from S42
The conditions below are not part of S42.322P, but a patient may have both at the same time. When documentation supports it, S42.322P and the excluded code may both be reported.
- periprosthetic fracture around internal prosthetic shoulder joint (M97.3)
Excludes2 — not included here — inherited from S42.3
The conditions below are not part of S42.322P, but a patient may have both at the same time. When documentation supports it, S42.322P and the excluded code may both be reported.
How long has S42.322P existed?
S42.322P 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.
