What does the 7th character "K" mean in S22.23XK?
In S22.23XK, the 7th character K means subsequent encounter for fracture with nonunion. The 7th character is required for S22.23XK to be a valid, complete code.
Same condition, different episode of care — switch the 7th character:
Which MS-DRGs does S22.23XK group to?
S22.23XK 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, S22.23XK is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
How is S22.23XK listed in the Alphabetic Index?
The Alphabetic Index lists these routes under S22.23, the nearest indexed parent of S22.23XK. Use them to find the family, then select the specific code.
- Fracture, traumatic › manubrium › dissociation from sternum (abduction) (adduction) (separation)
Excludes1 — never code together — inherited from S22
The conditions below can never be reported together with S22.23XK on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- transection of thorax (S28.1)
Code first — inherited from S22
The underlying condition below must be sequenced before S22.23XK. S22.23XK describes a manifestation and cannot be the principal or first-listed diagnosis.
Use additional code — inherited from Chapter 19
Report an additional code alongside S22.23XK to fully describe the condition. S22.23XK 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 S22.23XK, but a patient may have both at the same time. When documentation supports it, S22.23XK and the excluded code may both be reported.
Excludes2 — not included here — inherited from S20-S29
The conditions below are not part of S22.23XK, but a patient may have both at the same time. When documentation supports it, S22.23XK and the excluded code may both be reported.
- burns and corrosions (T20-T32)
- effects of foreign body in bronchus (T17.5)
- effects of foreign body in esophagus (T18.1)
- effects of foreign body in lung (T17.8)
- effects of foreign body in trachea (T17.4)
- frostbite (T33-T34)
- injuries of axilla
- injuries of clavicle
- injuries of scapular region
- injuries of shoulder
- insect bite or sting, venomous (T63.4)
Excludes2 — not included here — inherited from S22
The conditions below are not part of S22.23XK, but a patient may have both at the same time. When documentation supports it, S22.23XK and the excluded code may both be reported.
Code also — inherited from S22
Two codes may be needed to describe the condition fully. Whether S22.23XK is sequenced first depends on the reason for the encounter.
How long has S22.23XK existed?
S22.23XK 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.
