D68.4 — Acquired coagulation factor deficiency
D68.4 is a billable, specific ICD-10-CM code for acquired coagulation factor deficiency. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- vitamin K deficiency of newborn (P53)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Deficiency of coagulation factor due to liver disease
- Deficiency of coagulation factor due to vitamin K deficiency
Excludes1 inherited from the categories above D68.4
These are not written on D68.4, but they bind it: a note on a category applies to every code beneath it. Billing D68.4 with anything listed here is a denial.
Excludes2 inherited from the categories above D68.4
Also inherited, and the opposite of Excludes1: these conditions are not part of D68.4, but a patient can have both, so you may code both.
Other codes that can never be billed with D68.4
These codes carry an Excludes1 note pointing at D68.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D68.4 alone.
Risk adjustment
D68.4 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.
Medicare coverage
D68.4 is named in 5 Medicare coverage policies — 5 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How D68.4 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 D68.4.
