S49.001G vs S49.002G

S49.001G (Unspecified physeal fracture of upper end of humerus, right arm, subsequent encounter for fracture with delayed healing) compared with S49.002G (Unspecified physeal fracture of upper end of humerus, left arm, subsequent encounter for fracture with delayed healing), from the official CMS tabular data.

Summary

These codes name the same condition on opposite sides of the body, so the documented side decides which one applies.

MedCoder-derived
What is different?

Title wording.The titles differ in one word, “right” (S49.001G) versus “left” (S49.002G): S49.001G is “Unspecified physeal fracture of upper end of humerus, right arm, subsequent encounter for fracture with delayed healing”; S49.002G is “Unspecified physeal fracture of upper end of humerus, left arm, subsequent encounter for fracture with delayed healing”.

Registry fact

Can these codes be reported together?

One side per condition.S49.001G and S49.002G name the same condition on opposite sides of the body. Same category and title, differing only in which side is affected — the documentation decides which one applies, and a bilateral code is reported only where the code set provides one.

MedCoder-derivedGuide: Laterality coding

Is there an Excludes1 relationship?

None.Neither entry carries an Excludes1 note that names the other code.

Official rule

Is there an Excludes2 relationship?

None.Neither entry carries an Excludes2 note that names the other code. S49.001G carries 4 Excludes2 notes and S49.002G carries 4 Excludes2 notes covering other codes; the side-by-side table quotes them.

Official rule

Is one more specific?

No.Both titles are unspecified forms within category S49, and neither is a subdivision of the other.

Registry fact

Is one a parent or header code?

No.Both are billable codes, and neither contains the other.

Registry fact

Are there sequencing instructions?

None.Neither entry carries a Code First or Use Additional Code note that names the other.

Official rule

Are there other coding relationships?

Yes.Same condition, opposite side. S49.001G and S49.002G name the same condition on opposite sides of the body.

MedCoder-derivedGuide: Laterality coding

Official rule: a tabular instructional note or a section of the ICD-10-CM Official Guidelines, quoted as published. Registry fact: the codes’ own published attributes (titles, billable status, position in the hierarchy, code set). MedCoder-derived: a reading MedCoder computes from those facts; it is not itself a rule.

What we found

Same condition, opposite side.S49.001G and S49.002G name the same condition on opposite sides of the body.

Same category and title, differing only in which side is affected — the documentation decides which one applies, and a bilateral code is reported only where the code set provides one.

What to review

Report the side the documentation names. Where the code set provides a bilateral code and both sides are documented, use it instead of the pair.

Why it matters

These codes share a category and title and differ only in the side affected. The documentation decides which applies, and a bilateral code is reported only where the code set provides one.

Notes are the code’s own tabular entry, quoted as published. A note that names the other code is the one the verdict above rests on.
