What does the 7th character "Q" mean in S52.025Q?
In S52.025Q, the 7th character Q means subsequent encounter for open fracture type I or II with malunion. The 7th character is required for S52.025Q to be a valid, complete code.

Which MS-DRGs does S52.025Q group to?
S52.025Q 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, S52.025Q is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
How is S52.025Q listed in the Alphabetic Index?
The Alphabetic Index lists these routes under S52.02, the nearest indexed parent of S52.025Q. Use them to find the family, then select the specific code.

- Fracture, traumatic › ulna › upper end › olecranon process › nondisplaced (abduction) (adduction) (separation)
Excludes1 — never code together — inherited from S52
The conditions below can never be reported together with S52.025Q 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 forearm (S58.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside S52.025Q to fully describe the condition. S52.025Q 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 S52.025Q, but a patient may have both at the same time. When documentation supports it, S52.025Q and the excluded code may both be reported.
Excludes2 — not included here — inherited from S50-S59
The conditions below are not part of S52.025Q, but a patient may have both at the same time. When documentation supports it, S52.025Q and the excluded code may both be reported.
Excludes2 — not included here — inherited from S52
The conditions below are not part of S52.025Q, but a patient may have both at the same time. When documentation supports it, S52.025Q and the excluded code may both be reported.
Excludes2 — not included here — inherited from S52.0
The conditions below are not part of S52.025Q, but a patient may have both at the same time. When documentation supports it, S52.025Q and the excluded code may both be reported.
How long has S52.025Q existed?
S52.025Q 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.
