What is ICD-10 code D68.8?

D68.8 is the ICD-10-CM diagnosis code for Other specified coagulation defects. Other specific blood clotting disorders that don't fit into the main categories of bleeding or clotting disorders. D68.8 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. D68.8 is part of the FY2026 ICD-10-CM code set published by the CMS National Center for Health Statistics and used on Medicare, Medicaid, and commercial claims in the United States.

Yes. D68.8 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. D68.8 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

What is the V28 vs V24 difference for D68.8?

CMS phased in the V28 risk adjustment model over payment years 2024 (33%), 2025 (67%), and 2026 (100%), replacing V24. V28 consolidates HCC categories, removes some lower-acuity conditions, and recalibrates RAF weights across the entire model. D68.8 was a payment HCC under V24 (Coagulation Defects and Other Specified Hematological Disorders) but the V28 recalibration removed it from the risk adjustment model. Both models can still appear in legacy data and in payer-specific lookback periods.

What should coders know when reporting D68.8?

This is a catch-all code for rare or unusual coagulation defects; provide detailed documentation of the specific defect Ensure more specific codes are not available before using this code Because D68.8 maps to a payment HCC, the documentation must also satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's risk adjustment score.

Buddy Documentation Tip

HCC Buddy guidance

Document the specific coagulation defect identified, relevant laboratory testing (coagulation panels, specialized assays), clinical manifestations (bleeding or thrombotic), and underlying etiology when known.

Record treatment approach and monitoring plan appropriate to the specific defect.

MEAT Support

Audit Caution

HCC Buddy guidance

This code should be a last resort within the D68 category — review all available specific codes before selecting D68.

Query the provider for additional specificity that might allow a more precise code assignment. Document the clinical significance of the coagulation defect to support medical necessity.

Common Mistakes

HCC Buddy guidance

D68.9 (Coagulation defect, unspecified) — less specific and should be avoided when the condition can be characterized

D65 (DIC) — specific consumptive coagulopathy with its own code

D68.4 (Acquired coagulation factor deficiency) — specific to acquired factor deficiencies.

Last updated: FY2026 ICD-10-CM Apr update, Apr 1, 2026 through Sep 30, 2026. CMS-HCC V28 is 100% phased in for payment year 2026.

Is D68.8 an HCC code?

Yes. D68.8 maps to Coagulation Defects and Other Specified Hematological Disorders under the V24 model but is not retained in V28.

Each model's RAF is its CMS base weight for that model's standard population, so weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.

MEAT Criteria for D68.8

For D68.8to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically, it has to be re-documented and supported each calendar year.

MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
EEvaluate: test results, medication response, or physical findings reviewed by the provider
AAssess: explicit mention in the assessment or plan with acknowledgment of status
TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis

Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed D68.8 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

D68.8 is the ICD-10-CM diagnosis code for other specified coagulation defects. Other specific blood clotting disorders that don't fit into the main categories of bleeding or clotting disorders. D68.8 sits in the ICD-10-CM chapter for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (d50-d89), within the section covering coagulation defects, purpura and other hemorrhagic conditions (d65-d69).

Under the older CMS-HCC V24 model, D68.8 maps to Coagulation Defects and Other Specified Hematological Disorders (HCC 48) with a community, non-dual, aged base RAF weight of 0.192. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.

This is a catch-all code for rare or unusual coagulation defects; provide detailed documentation of the specific defect. Because D68.8 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D68.8 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•This is a catch-all code for rare or unusual coagulation defects; provide detailed documentation of the specific defect
•Ensure more specific codes are not available before using this code

Clinical Significance

Other specified coagulation defects captures coagulation abnormalities not classified in more specific D68 categories, including conditions such as fibrinolytic defects, hyperfibrinolysis, and other rare coagulation pathway disorders. This is a residual code that should only be used when no more specific code accurately describes the condition.

Documentation Requirements

✓Document the specific coagulation defect identified, relevant laboratory testing (coagulation panels, specialized assays), clinical manifestations (bleeding or thrombotic), and underlying etiology when known.
✓Record treatment approach and monitoring plan appropriate to the specific defect.
