Yes. E72.09 is a billable, specific ICD-10-CM code and is valid for submission on a claim.

Where does E72.09 sit in the tabular list?

Endocrine, nutritional and metabolic diseases (E00-E89), in the block Metabolic disorders (E70-E88).

What cannot be coded together with E72.09?

E72.09 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above E72.09 (E72.0, E72) and apply to it just the same.

E72.09

E72.09 — Other disorders of amino-acid transport

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Fanconi (-de Toni) (-Debré) syndrome, unspecified

Excludes1 inherited from the categories above E72.09

These are not written on E72.09, but they bind it: a note on a category applies to every code beneath it. Billing E72.09 with anything listed here is a denial.

Written on E72.0 — Disorders of amino-acid transport

disorders of tryptophan metabolism (E70.5)

Written on E72 — Other disorders of amino-acid metabolism

disorders of:
aromatic amino-acid metabolism (E70.-)
branched-chain amino-acid metabolism (E71.0-E71.2)
fatty-acid metabolism (E71.3)
purine and pyrimidine metabolism (E79.-)
gout (M1A.-, M10.-)

Other codes that can never be billed with E72.09

These codes carry an Excludes1 note pointing at E72.09. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E72.09 alone.

E72.04Cystinosis

Risk adjustment

E72.09 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

How E72.09 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to E72.09.
