What does the 7th character "P" mean in S79.012P?
In S79.012P, the 7th character P means subsequent encounter for fracture with malunion. The 7th character is required for S79.012P to be a valid, complete code.
Same condition, different episode of care — switch the 7th character:

Which MS-DRGs does S79.012P group to?
S79.012P sits in MDC 08 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 521Hip Replacement with Principal Diagnosis of Hip Fracture with MCCsurgical
- 522Hip Replacement with Principal Diagnosis of Hip Fracture without MCCsurgical
As a secondary diagnosis, S79.012P is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
How is S79.012P listed in the Alphabetic Index?

- Fracture, traumatic › femur, femoral › capital epiphyseal (abduction) (adduction) (separation)
- Slipped, slipping › epiphysis › capital femoral › acute
- Fracture, traumatic › femur, femoral › upper end › physeal › Salter-Harris type I (abduction) (adduction) (separation)
Excludes1 — never code together — inherited from S79.0
The conditions below can never be reported together with S79.012P on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes1 — never code together — inherited from S79.01
The conditions below can never be reported together with S79.012P on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- chronic slipped upper femoral epiphysis (nontraumatic) (M93.02-)
Use additional code — inherited from Chapter 19
Report an additional code alongside S79.012P to fully describe the condition. S79.012P 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 S79.012P, but a patient may have both at the same time. When documentation supports it, S79.012P and the excluded code may both be reported.
Excludes2 — not included here — inherited from S70-S79
The conditions below are not part of S79.012P, but a patient may have both at the same time. When documentation supports it, S79.012P and the excluded code may both be reported.
How long has S79.012P existed?
S79.012P 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.
