Summary

No tabular note links these codes. Both belong to category M1A, and nothing in the tabular list prevents reporting each when it is documented.

Registry fact
What is different?

Title wording.The titles differ in one word, “without” (M1A.39X0) versus “with” (M1A.39X1): M1A.39X0 is “Chronic gout due to renal impairment, multiple sites, without tophus (tophi)”; M1A.39X1 is “Chronic gout due to renal impairment, multiple sites, with tophus (tophi)”.

Registry fact

Can these codes be reported together?

No instruction prevents it.No note in either entry names the other. Both belong to category M1A; each may be reported when its own documentation is present.

Registry fact

Is there an Excludes1 relationship?

None.Neither entry carries an Excludes1 note that names the other code. M1A.39X0 carries 1 Excludes1 note and M1A.39X1 carries 1 Excludes1 note covering other codes; the side-by-side table quotes them.

Official rule

Is there an Excludes2 relationship?

None.Neither entry carries an Excludes2 note that names the other code. M1A.39X0 carries 1 Excludes2 note and M1A.39X1 carries 1 Excludes2 note covering other codes; the side-by-side table quotes them.

Official rule

Is one more specific?

No.Neither is a subdivision of the other, and neither title is the unspecified form; they describe different conditions within category M1A.

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?

None found.No laterality, encounter-phase, Table of Neoplasms, Table of Drugs and Chemicals, or history-versus-active-disease relationship links these codes.

MedCoder-derived

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. How to read the labels

Can these codes be reported together?

Yes, when each is documented. M1A.39X0 and M1A.39X1 both belong to category M1A.

No Excludes1/Excludes2 relationship exists between these codes in the official tabular list. The code titles state what each one covers, and the documentation decides which applies.

Side by side

Similar descriptions do not make codes interchangeable. The documentation and the official instructions decide which code applies.

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. In a row that differs, notes every code shares are dimmed.
