Excludes1 — never code together — inherited from S42
The conditions below can never be reported together with S42.366 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 S42.366 to fully describe the condition. S42.366 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 S42.366, but a patient may have both at the same time. When documentation supports it, S42.366 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S40-S49
The conditions below are not part of S42.366, but a patient may have both at the same time. When documentation supports it, S42.366 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S42
The conditions below are not part of S42.366, but a patient may have both at the same time. When documentation supports it, S42.366 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 S42.366, but a patient may have both at the same time. When documentation supports it, S42.366 and the excluded code may both be reported.
